The VPN or the Virtual Private Network is a service is an option that has gained immense popularity all over the world. The Windows VPN service provider offer an alternative to a dedicated personal network connection for the different corporate offices across the globe. Actually, VPN is a private network built upon the Internet network having public access. It uses the different security means and the encryption followed by the public network. This in turn helps in maintenance of the organizational secrecy and keeps the information private. This is one of the reasons why VPN is also referred as Internet VPN.

VPN has even facilitated the different companies to get connected to the office servers from places other than office. Now, you must be curious to know about how to VPN? It is the Point-to-Point Tunneling Protocol (PPTP) in the VPN servers enables the users of Windows or Mac to log on to the Power Elf Servers, no matter, which part of the world they belong to. This is done by creating a secured connection of 128-bit encryption through the PPPT from the local computer to the VPN servers. You can well consider the connection to be absolutely secured as the data and both the addresses of the source network and the destination are in encrypted form.

It is the Internet through which the virtual connections of VPN work and get connected with the remote networks and sites. Thus, no interruption is caused to the users during the time of accessing the network. Therefore, the VPN is slowly emerging as a great means to get connected to the network of the office or to the LAN.

The features that strongly make way to the security attributes of VPN and the major elements include the firewall protection, the encryption, and the passwords. They provide a set of security methods to the entire system. The commonest form of VPN happens to be a remote access VPN. This provides assistance in creation of a secured tunnel joining the office server to your system.

The Virtual Private Network also has great utility in the countries, which practice Internet censorship. Let’s take the instance of China, which has more Internet users than the entire US population. They frequently access the YouTube, the Facebook and even the Wikipedia but the worst part is that there are limitations set by the communist government and people are not allowed to access the website of their choice. It is the Great China Firewall; they need to cross in order to do so. Hence VPN comes to their help. With the help of it they have full access to the net but minus he risk of getting tracked. So, it can be considered as an answer to your query about how to unblock websites?

Alonweb offers a free VPN service and offers an open VPN tunneling service constituting a Secure Socket Layer. It has several servers to choose from and it comes completely free. It will surly make the users feel save over the net. The free VPN service is generally offer connection to the users via two servers and though they have some limitations but still it is quite beneficial to all the users.

To make collocation centers work efficiently, there are basic features or special characteristics that should be considered. This is very important so that clients are assured of the performance of said center, as far as protecting their client’s interests.

Fire protection – A collocation center should be backed up by reliable fire protection systems to prevent accidental fires. The systems include active and passive design elements and the implementation of a program for fire prevention. Clients should consider this basic feature before signing any contract for collocation services. Remember that you are entrusting your data and other business applications to a privately-owned servers. Therefore cautions should be in the priority, whether the company can deliver client expectations.

Usually, a smoke detector is being installed to easily give warning if a fire is developing to prevent the development of flame. There is also a fire sprinkler system which can help control accidental fires from developing further damage. The system also includes the installation of fire walls and clean agent fire suppression gaseous systems which can suppress a fire earlier than using the fire sprinkler systems.

19-inch racks – This is also another feature you should consider. A collocation center must provide at least 23-inch rack for telecommunications equipment, cabinets and other cages for the tenants’ physical access, cable racks or tray for power cables and fibreguide.

Air conditioning – To control the humidity and temperature of the place, air conditioning must be excellently working. There are recommended humidity and temperature range for the so-called optimal electronic equipment conditions. This is also a very important feature we should see in collocation centers. If they don’t have this system operating efficiently, then their services may have some problems. Therefore, you should also check this as part of the most basic and safety features we can get from these centers.

However, there are also agencies in the country auditing and checking the conditions of collocation centers, whether these centers live up to certain standards, reliability. The most common here is the tier system used by the Uptime Institute and also SAS 70.

Most collocation centers have generators running on diesel fuel so that in cases of power curtailment, they can easily back the servers. These generators have battery back up systems so that the centers can operate 24/7 to secure the client’s data and other business applications.

This is the main reason why clients should carefully understand the basic features and characteristics of collocation centers before they hire their services. It is only a matter of practicing caution since there are now lots of collocation centers in the country.

It seems that whenever you talk about an upgrade or new installation of a company’s voice/data network these days you hear the buzz word “ethernet” sometime in the conversation. With all the buzz… should you seriously consider ethernet in the mix for your network solution?

Now think about that for a moment. Are you just “jumping on the bandwagon”… or is there some truth to all this hullabaloo?

To answer that let’s get serious for a moment… no gushing idol worship. Just facts.

First …. it’s very clear that today Ethernet has gone from a nice to have option to the preferred choice for WAN (Wide Area Networks) access links. Many companies also use it in their backbone for IP connectivity. So the question often is “why not Ethernet” ….. rather than “should you use it.”

For example it is increasing commonplace that in a campus network just about all high bandwidth communications is Ethernet based. Also many things that used to be separate such as voice, CCTV, security/card locks can be migrated. Although you might need something to drive the migration. Can someone say cost savings??? Don’t forget scalability with future technologies and increased performance efficiency too. All three will go over very well with your Big Boss …. and your shareholders.

If you need a few bullet points to drive home this message to that audience …. try using these:

- You really don’t need a router. It is simply an Ethernet Handoff to your network.

- As you increase in bandwidth …. the per meg price goes down much quicker than with DS3 or OC3 bandwidth.

- For off-net/on-net sites Ethernet can be much cheaper than standard DS3 or OC3 bandwidth …. because you do not have to deal with loop costs.

However, I don’t think Ethernet is really the common denominator, but IP (which tends to use Ethernet in most places). Since that means you don’t need Ethernet everywhere and you can integrate useful technologies you might need – MPLS, VSAT, ADSL, and DS3 for example.

Be aware though that some parts of networks are likely to not be Ethernet compatible for a long time. The issue with “everything must be xx” is not whether you can get xx (sic Ethernet) in most places, but how to cope with the last few “hold outs”.

A definite pro is that ethernet remains a layer 2 service. Which if you buy from a carrier means that you are in control of the routing. Whereas if you take an IP VPN service this will impact your internal routing configuration. Layer 2, Ethernet based connectivity between sites gives a lot of flexibility and often improved latency/jitter performance.

So if you’re using IP today on SDH services then a migration to Ethernet should be a lot simpler. But again this depends on the scenario. Most carriers now use Ethernet as the last mile and also for backbone connectivity. This has provided higher speeds without the capital outlay …. and has the requisite reliability you should expect.

I also wouldn’t use Spanning Tree and so would rely on the Network Layer to take the path decisions …. as this is a lot more deterministic and saves having multiple different protocols performing on the fly updates. Any IP application including voice and video should run just the same as over SDH …. but Ethernet would give you the options of putting Voice into it’s own VLAN. Controlling bandwidth in this manner …. incorporating Ethernet …. should be so much cheaper. You could over engineer the backbone and keep things simple.

There are no real drawbacks using Ethernet in my mind …. and I personally believe that this would give you more flexibility than either a traditional SDH structure or an IP VPN based network.

The only Cons I can think of relate to the maintenance and troubleshooting of the network. Depending on your architecture and design, it may be a nightmare to maintain the network. For example, point-to-point is simple, but rings and mesh is challenging and will require clever and flawless design.

You really need to design and test the network carefully. You need to be aware of the type of services you will be running. Such as constant traffic, bursty traffic, low-latency traffic etc… as all of that will impact on your network and will require careful configurations. You need to have your QoS (Quality of Service) planned accurately if working with VLAN’s or different types/classes of traffic.

Designed correctly, Ethernet models work well, but poorly implemented ones often have challenges. Its important for you to understand that Ethernet based WAN is not simply “plug-n-play”. It requires additional planning and setup.
Overall I think there are many more pros than cons for choosing ethernet for your voice/data network . We are seeing lots of improvements to Ethernet these days via various industry working groups ….. as well as evolving packet transport technologies such as MPLS-TP and PBB-TE. So the future of etherent looks even brighter.

To get right to the point ….. I would not hesitate to recommend Ethernet as a viable solution. It is a cheap and scalable solution.

Indian weddings are becoming grander and elaborate. All aspects of wedding be it the decorations, catering, video and photography have become stylized and extravagant. Can music be far behind? With event managers and wedding planners getting into the picture the whole rigmarole has become streamlined and organized.

Wedding entertainment has undergone a total transformation and they are planned in an attractive manner with even celebrities making an appearance!

You can risk a DJ, if you want the bride to elope with the disc jockey. Those who have seen the Rahul Bose, Mallika Sherawat starred – Pyar ka side effects will know what I mean! Just joking!

On a more serious note, having live music belting out chart busters seems to be the order of the day.

The advantage of having a DJ as an entertainer is that he knows the pulse of the audience. It is his job – to keep the listeners entertained and he does it with élan.

However, it is important to choose a right DJ for the occasion. Most of them have gift of the gab! But, the DJ’s profile should match the tastes of your guests. It is not discrimination rather a common sense approach. It is like choosing a comedian, whether you want a slap stick or a witty guy for the show! It depends on the audience.

Similarly, you want a DJ who can broadcast good music and at the same time keep the audience entertained with his wise cracks and presence of mind.

The biggest advantage of a DJ is his ability to interact effectively with the audience. However, it is also his weak point because unless the DJ is able to read the pulse of the audience, his repertoire would prove futile.

One sure fire way to choose a DJ would be experiencing it first hand. By which, either you would have seen him perform at a wedding or it could be a recommendation from someone whose taste you trust implicitly.

Another important aspect in fixing a DJ is putting things in writing. Everything should be clear in the contract:

Duration of performance

Most DJs have a time fee. So you need to make it clear to them about the duration of performance and what extra costs for extensions.

Choice of songs

If there are many older guests, then blaring out loud numbers can be odious. Also, you might have a list of favorites that you want played at your reception. Besides, check if the DJ is open to listener’s request and if he can keep stock of ‘most wanted’ songs as a back up.

Fees

While you would like to hire the best talent, it is important to know how much you are prepared to shell out for an evening’s entertainment. It is a personal preference and you might want to put that in your agreement to avoid hidden costs.

Acoustics

This is an often ignored aspect. It will be an advantage if the DJ knows the venue. The acoustics can be arranged accordingly. Very often the music is so garishly loud that one leaves with a headache. Music is at its best when soothing to the ear. It needs to be emphasized to the DJ.

Though the nadaswaram and shennai have always been central to the wedding ceremony most couples prefer an interactive entertainment and opt for the kind of music that would keep the younger generation on a high note. Hence, increasingly there are couples who decide on having a DJ entertaining them.

So make the most of it and have fun while doing so!

Along with the current struggling economy, crime has steadily increased over the last few years. This is for obvious reasons, since more and more people are caught up in a financial struggle some of them will inevitably resort to committing crimes. The most common in tough times as burglaries. Although security personnel are on hand to guard businesses and commercial areas, homes have a far less visual barrier between them and criminals looking to steal people’s belongings.

One of the best ways to deter home theft is through the use of a security camera system. These systems come with a very wide range of options, technologies, and prices. Probably the most flexible among these camera systems are the wireless variety since they do not require cabling, drilling, etc. They can be hidden, although a better option would to make it obvious your home is protected. That way if a criminal is scouting out your home as a target, they will notice the security system and be much less likely to invade.

Internet-based systems allow you to monitor the cameras from remote locations. The signal is then transferred through a local area network (LAN) adapter and then to an IP address. As a result, you can monitor your home from anywhere in the world with an Internet connection. Some systems even offer e-mail alert’s if movement is detected outside of your home.

Most home security cameras are outfitted with a 9 V battery which offers 5 to 10 hours of uptime. Any slight movement will alert one of these cameras, and then it will instantly begin recording the area. However, for best recording and playback ability, we suggest getting a camera with the highest resolution you can afford. Many cameras have low resolution and offer little more than a fuzzy, unusable recording.

Another great option for recording movement is the digital video camera, which is smaller than non-digital cameras. They also don’t require a tape to record. The data is then stored in the memory for transfer later on.

Security camera systems have been available for many years, although with advancing technology and decreasing prices they are now available to the average person simply wants to protect their greatest investment and themselves. They provide peace of mind when you’re away from your home and allow you to sleep better at night knowing that your family and valuable possessions are well protected.

When it comes to the way we pay, today the economy is funded on electronic dollars more than ever before. With many options to choose from that involve no actual cash transaction, consumers are enjoying the ease of credit card and debit cards to make their day to day purchases. While in the past the act of paying with a credit card was a complicated process, involving making an impression of the card on carbon paper, all by hand, today it is as easy as waving a small key-tag card in front of the cashier. There isn’t even anything to sign for many transactions, and customers have an accurate record of all of their spending. When travelling internationally, paying by credit or debit card allows customers to get up-to-the-minute exchange rates, and not worry about finding local currency. Many cards allow consumers to save up points towards valuable rewards like airfare, cash, electronics and travel bonuses. With all the perks of using electronic money, plus the ease of keeping track of our bank statements online, it’s hard to deny it is the most efficient form of money management invented yet by man. For internet users still stuck with dial-up, however, the ease of internet money management may not be so convenient.

With security better than ever on bank websites, in order to access our accounts many people must enter several passwords, and pass through several slow-loading, heavily encrypted security pages. When buzzing around the net on a DSL or other LAN internet provider’s network, online bankers can easily get to their valuable money info. Once online users can check their savings, checking and money market account balances, review spending, and transfer money between accounts. Many users even choose to get real-time status updates sent to their email or blackberries, to keep track of kids, spouses, or employees with access to personal or business credit or debit cards. Sounds great to the average internet user, but to a dial-up user this process can be a nightmare. For that very reason, many people living in rural or remote areas, who are still relying on dial-up internet, are making the long overdue switch to satellite internet.

With satellite internet broadband speeds, users are able to access all of the heavy pages that once tied up the internet, phone lines, and computers for hours, in just seconds. With the ability to upload and download large amounts of info without worrying about missing important calls, tying up the phone line, or experiencing connectivity issues, the average satellite internet user is enjoying the use of internet applications he or she could never access before. For those attempting to not only bank from home, but work or study from home, the speed of satellite broadband is allowing them to succeed in a way never possible before.

Living in a rural or remote area can already make everyday tasks like banking a challenge. Every time a bank customer must make a deposit, check an account, or withdraw cash, the customer must get in the car and drive, sometimes for hours, to the nearest commercial center. Banking at home would save these customers valuable time and money. Saving time and money is what the convenience of satellite internet is all about, as users are able to accomplish more right from the comfort of their own homes than they ever believed possible.

With satellite internet it’s easier to run errands from the comfort of your home office than ever before. Go online to check out wildblue satellite internet today!

Buying a computer or hardware may not be easy for a certain individual. After you buy a laptop you may require hardware. If you would like high performance, you’ll be able to think about new ones; however, a desktop is nice for saving money. I have simple tips that you should know before buying computer or hardware.

Here are tips and tricks in the purchase of computers or hardware:

1. If limited funds to purchase computers, use the following ways:
Purchase main board contained on-board hardware is another therein. Like the i810 + AGP main board’s on-board share 2Mb + on-board 3D sound (Yamaha XG chipset) + on-board LAN + on-board V90 fax modem 56k, the market can be purchased for U.S. $ 80. This will save compared to buying the hardware in the unit, with almost same quality. Even the quality of on-board AGP is nearly equal to 8MB AGP card, although only requires 2Mb of RAM your computer, but it’s there in the memory buffer main board. Note: in order to share the AGP memory not interfere with computer operation, it is better if done adding RAM.

2. If your budget is really limited, you can use hardware that the condition is still good. Please, buy used processors, because the damage is rare in the processor, and you can buy other hardware with the new price. Make sure you did not buy the second hard disk, CD-ROM, and RAM, because of the damage from the hardware is very high.

3. If you try to over clock, make sure not to change the voltage because it would reduce the age of the hardware. We have the AMD processor over clock since the beginning of the assembly and it still works well because it does not change the voltage.

4. Overall, after you make sure you buy a computer
get WARRANTY from the seller, and you can examine it carefully. For example:
a. Main board ASUS has a 3-year warranty from manufacturer.
b. Visipro brand RAM has a lifetime warranty.
c. RAM NeoPower brands have a lifetime warranty.

For the information of everybody, a collocation center is also used as a web hosting service, by which a lot of companies patronize this service to run their servers. This particular service of collocation centers is also managed by IT professionals. The IT staffs that operates collocation servers guarantees their customers continuous access to their data and applications enabling them to modify and edit work related tasks. The servers are highly secured and have back-up power systems that automatically activates in case of power interruptions and blackouts.

There are a lot advantages when choosing collocation servers.Choosing a collocation center still gives customers a lot of advantages. Eliminating your task of hosting your own web server is one of the very basic advantage it offers. Second, the collocation server you are connected to will be the one to ensure your data and application’s security and that it is always up on the Internet. Among of the many advantages that you will be having is the fast uploading of files for your server as collocation centers have very fast Internet connection speeds. Eliminating any connection delay and lag to your server.

The servers of a collocation center in a facility are featured with fire prevention systems and cooling systems. It is guarded by security guards seven days a week and 24 hours a day. A company’s and organizations private data are well ensured by the collocation company.

There are still some companies that are thinking twice about going with collocation centers. Some companies prefer to have their own dedicated servers than to connect to collocation servers. What some companies and organizations do not know is that collocation servers and private servers are just the same and both these servers operate exactly the same as the other. The difference is that when having private servers, you will have to hire IT people to manage your servers and that will add up to your expenses. While a collocated server on the other hand is already ready to provide service and security for your servers with other benefits.

For certain people and individuals who have their own websites or blogs, going with a collocation server is the best thing to do as collocation centers have professional staffs that manages their servers ensuring stable accessibility 24/7.

There a lot of collocation services out there today, most of them are offered by web hosting companies that provides network solution services. Of course before choosing any collocation services, you must consider many factors like if it can really bring you the benefits that your business needs and if they are really a very dedicated server to their customers. Also, be sure enough to distinguish that the service providers you are choosing have professional and skillful staffs that you can trust your business needs with. Search for well known web hosting enterprises on the Internet to see a list of top notch collocation companies.

We all are so reliant on technology that at times we take it for granted. We take for granted that it will always work when we need it, and that it is designed for resiliency and reliability. In many cases, it is not the design that gets in the way but rather outside factors that exacerbate the issue. One of the main ones, key to the operation of any advanced technology, is rooted in science over 100 years old and relatively unchanged since.

While most of us think that our old friend Ben Franklin discovered electricity with his famous kite flying, the real father of electrical power is English scientist William Gilbert. He extrapolated the writings of Thales of Miletus from around 600 BC of rubbing amber to produce a charge. Nearly 2200 years later, Gibson discussed the ability to take and conduct charges in many different substances and coined the term “electricity” from the Greek word for amber. Around the world, several different machines were built to create these charges leading to devices we still see today such as the Van De Graff generator which is used as a particle accelerator.

Electricity remained a curiosity until the Leyden jar was built in 1745 by Pieter van Musschenbroek which stored static electricity for a single, total discharge. I guess you could say it was the first battery! Many others sped the process of making power available and usable including Luigi Galvani and Alessandro Volta who created the forerunner of the modern battery, the voltaic pile and Michael Faraday who worked with magnets to produce a stable power generating field. Then we marveled at Thomas Edison with his DC generator and Joseph Swan who created the first incandescent light bulb. They were followed by Nikola Tesla who invented the first motor to create AC or alternating current which George Westinghouse saw immediately as the future of electric generation and bought the technology. Lastly, we cannot forget James Watt, Andre Ampere, and George Ohm whose contributions were so paramount that units of electric power were named after them!

Now that we’ve established where electricity came from, we bow to the knowledge that without it our modern 21st century world would stop dead in its tracks. With increased reliance on network computing, businesses large and small would be severely impacted if those systems were not available, so proper planning for power to those server rooms and data centers is beyond critical. Ironically, in many small to mid-sized organizations guaranteeing good clean power flow is almost never addressed.

To that end, proper planning and evaluation of the power consumption of IT equipment is as important as the setup and deployment of the gear itself. The first step is providing constant power in a clean, consistent wave. Without getting into the tenets of electrical engineering, keep in mind electrical power comes in “watts” which describes the flow of electricity. Electric power, also called current, travels along the wires in a wave.

This is important to the proper care of all devices that are fed by electricity. The continued shape of that wave is crucial to keeping devices running and also to their longer availability and lifecycle. What many people don’t take into account is the fact that the power that comes to your door from the electric company is rarely this consistent. We are acutely aware of and worry about power outages due to the immediate nature of the threat. Power goes out, equipment shuts off. It’s that simple. But it’s significantly more than that.

The jarring effect of sudden power loss can and does wreak havoc with sensitive electronic gear especially complex systems like PCs, servers, and other processor-based equipment. Over time, this will lower the life expectancy of these systems. The problem is there is no way to measure just how much time you are losing. It’s like avoiding your doctor’s advice to stop eating fatty foods or smoking. Maybe you will continue on for years without a problem, or maybe you’ll drop dead tomorrow from a heart attack.

Sudden power loss, or blackout, is not the only threat to your critical infrastructure. As I mentioned before, the flow of power is rarely consistent, and events such as brownouts and spikes are equally dangerous to equipment.Brownouts are defined as temporary reductions in power often due to over demand. When power is reduced during a brownout, lights may dim but servers and PC’s cannot slow down so they strain to keep running at their previous levels. Spikes are simply a sudden event that sends a jolt of extra current through the power grid. Most often this occurs during a thunderstorm when a bolt of lightning hits a power line, but lightening doesn’t have to be present for a spike to occur. Compare the sudden surge of power to a dam; if your local reservoir gets a sudden burst of water flow, it could break without the proper protections in place. The same is true for your sensitive network equipment.

We have seen what can be wrought as a result of inattention to power, so what do we do about it? Most commonly seen in the SMB marketplace are devices that mitigate the flow of electrical power called uninterrupted power supplies, or UPS. A UPS has a dual purpose, the most commonly considered is to keep power going to attached devices when a power outage hits. Yet a good UPS performs a significantly more important function, assuring a good clean power flow. When describing how events like spikes and blackouts can have serious impact on the performance and life of equipment, the consideration was there was no intermediate device between the power feed and the equipment. But a UPS, in addition to having battery back-up capability to keep power flowing, acts as a kind of filter to smooth out those fluctuations in the electric power wave. It’s akin to having a flow restriction device in your shower. Regardless of the flow of water from the main, the flow of water to the shower head is delivered at a nice, constant rate.

There are also optional features in these UPS devices that can be extremely beneficial. One would be a monitoring module that can be added to the UPS structure. For example, modules can generate alerts when power is compromised, or the temperature in the room fluctuates out of the acceptable range. Alerts can be sent to email addresses and/or mobile devices, and can be recorded and logged on the network for later analysis. For small and mid-sized business that don’t employ a dedicated IT person, some level of this capability is beneficial and allows alerts to be directly dealt with by the IT service provider.

UPS units are the minimal consideration in protection for a modern business network. In the small to mid-sized business with a simple server room that often also houses the company’s phone system, assuring consistent and uninterrupted power is nearly all they will need. But neglecting another environmental factor could also be disastrous.

I have seen many of these “equipment rooms” as cramped closets or repurposed office spaces, and in some cases with little or no HVAC venting. Proper cooling of the space must be considered or disruption and failure will occur to these sensitive systems.

There are guidelines for the proper amount of air conditioning to keep these spaces in the recommended temperature range of between 68 and 77 degrees Fahrenheit. Suffice it to say if this is not adequately planned for, you may be investing in new gear much sooner. Heat can literally fry system boards and wiring or cause cooling fans to overextend and fail. Because there are so many factors to weigh, getting a consultation from a professional is highly recommended. Even if you think you are safe because you only have one server and a little firewall, if they are crammed in an old broom closet (don’t laugh, I have seen this!), you are looking at the potential for a major failure.

As you ascend the ladder in server room size and the amount of equipment in it, there are more comprehensive solutions from a bevy of manufacturers such as American Power Conversion (APC), Liebert, Eaton and more. These range from rack-based solutions where the UPS and cooling are combined in a self-contained and enclosed unit, to huge blade server racks with rack-sized air handling. For the SMB space, APC has been the leader for years in solutions that fit both size and budget.

APC has several very thorough white papers including one titled “Cooling Strategies for IT Wiring Closets and Small Rooms,” by Neil Rasmussen and Brian Standley that has a wealth of information. The decision on what is best for your unique needs often hinges on price and how many features can be obtained for a reasonable investment.

In my experience, it is rare to see a small or mid-sized organization that needed to go to the lengths of an enterprise organization in regard to a server room. Features like raised floors to hide all the cabling, hot and cold row design, and multiple sources of power and connectivity are generally not necessary or affordable for the SMB. That said some SMBs have opted for a cloud-based infrastructure which essentially rents out space in large datacenters. Of course this nearly renders the discussion of power and cooling moot. I say nearly because you still will have some gear on-site, like the phone system or a firewall, and it will have to be protected too.

This white paper is a simple overview of the power and cooling needs of small and mid-sized business today. As this is written, Pennsylvania is preparing to deal with the uncertainty of power costs when previously enacted rate “caps” are lifted on January 1, 2011. While shopping for the best deal is going to be a huge part of that, making sure the power is protected and stable must be considered too.

Proper planning and consultation can help mitigate the potential for crippling budget increases and equally crippling failures. Find a trusted partner that can help your overall IT strategy and allow them to manage your network so the network won’t manage you! Whatever you do, leave the kite experiments to the experts. You’ll find ways to make the power you need more affordable like virtualizing servers, replacing PCs with thin client workstations, or telecommuting.

It seems that whenever you talk about an upgrade or new installation of a company’s voice/data network these days you hear the buzz word “ethernet” sometime in the conversation. With all the buzz… should you seriously consider ethernet in the mix for your network solution?

Now think about that for a moment. Are you just “jumping on the bandwagon”… or is there some truth to all this hullabaloo?

To answer that let’s get serious for a moment… no gushing idol worship. Just facts.

First …. it’s very clear that today Ethernet has gone from a nice to have option to the preferred choice for WAN (Wide Area Networks) access links. Many companies also use it in their backbone for IP connectivity. So the question often is “why not Ethernet” ….. rather than “should you use it.”

For example it is increasing commonplace that in a campus network just about all high bandwidth communications is Ethernet based. Also many things that used to be separate such as voice, CCTV, security/card locks can be migrated. Although you might need something to drive the migration. Can someone say cost savings??? Don’t forget scalability with future technologies and increased performance efficiency too. All three will go over very well with your Big Boss …. and your shareholders.

If you need a few bullet points to drive home this message to that audience …. try using these:

- You really don’t need a router. It is simply an Ethernet Handoff to your network.

- As you increase in bandwidth …. the per meg price goes down much quicker than with DS3 or OC3 bandwidth.

- For off-net/on-net sites Ethernet can be much cheaper than standard DS3 or OC3 bandwidth …. because you do not have to deal with loop costs.

However, I don’t think Ethernet is really the common denominator, but IP (which tends to use Ethernet in most places). Since that means you don’t need Ethernet everywhere and you can integrate useful technologies you might need – MPLS, VSAT, ADSL, and DS3 for example.

Be aware though that some parts of networks are likely to not be Ethernet compatible for a long time. The issue with “everything must be xx” is not whether you can get xx (sic Ethernet) in most places, but how to cope with the last few “hold outs”.

A definite pro is that ethernet remains a layer 2 service. Which if you buy from a carrier means that you are in control of the routing. Whereas if you take an IP VPN service this will impact your internal routing configuration. Layer 2, Ethernet based connectivity between sites gives a lot of flexibility and often improved latency/jitter performance.

So if you’re using IP today on SDH services then a migration to Ethernet should be a lot simpler. But again this depends on the scenario. Most carriers now use Ethernet as the last mile and also for backbone connectivity. This has provided higher speeds without the capital outlay …. and has the requisite reliability you should expect.

I also wouldn’t use Spanning Tree and so would rely on the Network Layer to take the path decisions …. as this is a lot more deterministic and saves having multiple different protocols performing on the fly updates. Any IP application including voice and video should run just the same as over SDH …. but Ethernet would give you the options of putting Voice into it’s own VLAN. Controlling bandwidth in this manner …. incorporating Ethernet …. should be so much cheaper. You could over engineer the backbone and keep things simple.

There are no real drawbacks using Ethernet in my mind …. and I personally believe that this would give you more flexibility than either a traditional SDH structure or an IP VPN based network.

The only Cons I can think of relate to the maintenance and troubleshooting of the network. Depending on your architecture and design, it may be a nightmare to maintain the network. For example, point-to-point is simple, but rings and mesh is challenging and will require clever and flawless design.

You really need to design and test the network carefully. You need to be aware of the type of services you will be running. Such as constant traffic, bursty traffic, low-latency traffic etc… as all of that will impact on your network and will require careful configurations. You need to have your QoS (Quality of Service) planned accurately if working with VLAN’s or different types/classes of traffic.

Designed correctly, Ethernet models work well, but poorly implemented ones often have challenges. Its important for you to understand that Ethernet based WAN is not simply “plug-n-play”. It requires additional planning and setup.
Overall I think there are many more pros than cons for choosing ethernet for your voice/data network . We are seeing lots of improvements to Ethernet these days via various industry working groups ….. as well as evolving packet transport technologies such as MPLS-TP and PBB-TE. So the future of etherent looks even brighter.

To get right to the point ….. I would not hesitate to recommend Ethernet as a viable solution. It is a cheap and scalable solution.

Online privacy and computer security has always been a common issue among all Internet users who have their own personal computers, be it a desktop or a laptop. There are a lot of things to be done in order to ensure that you have total protection. To avoid confusion here is a checklist that can serve as your guide:

Block Viruses and Hackers

Without a firewall and antivirus software, your computer will become vulnerable to threats such as viruses and hackers. It will be like leaving your house with the door unlocked.

Every Computer Needs a Firewall

Having a software firewall installed will regularly ask you to confirm if a computer program’s communication on a given port should be allowed or not. A hardware firewall may be able to block or allow all packets that pass in and out the port but it has no way of knowing which application started the communication on your computer system.

Use a Two-Way Firewall

The built-in Windows firewall is good but it would be better to use a firewall that has the ability to monitor and manage both incoming and outgoing network traffic. Any real-life backdoor program initiated on your computer will be blocked by a bidirectional firewall.

Update Your Internet Protection Regularly

Downloading and installing regular updates provided by vendors can help prevent email viruses from taking advantage of the flaws in your hardware and programs.

Set the Controls for Security

After updating the latest bug fixes and patches in your software, verify the security settings of the applications. Most commonly used programs offer minimal features in blocking viruses, stamping out cookies, and keeping spies off your computer and network.

Use Browser Privacy Settings to Block Unwanted Sites

You can use the settings on your browser to control the web content that you would allow. By doing so, websites can be prevented from doing nasty things on your computer.

Disrupt Email Threats

If your email program is prevented from carrying out attachments and scripts in the received messages and the program is updated to fix security flaws which have been recently discovered, you will have a better chance of keeping Trojan horse programs and viruses from invading your computer. Outlook and Outlook Express’ most recent versions have the wonderful ability of blocking dangerous attachments and all scripts through default settings. It will automatically place any incoming mail with HTML in the controlled security zone.

For those recipients who want to take a quick look into emails with attachments, Outlook Express allows them to see the files or scripts contained without even opening the email. By doing a right-click on the message, then Properties, Details Tab and Message Source in order, the exact text of the message can be seen.

Your Wireless LAN Should Use MAC Filtering

For maximum Internet protection, you should use multiple Internet security elements. If you have a wireless network, Media Access Control or MAC address filtering is a good security feature that your access point or wireless router can enable as an extra layer of protection to keep network hackers from gaining access to your system.

In today’s ever-busy world where we have tons of information to take care of and thousands of people to share it with, remote PC access software could be your best ally. Since it is impossible to remember everything and also to carry data with us wherever we go, the ability to access this data from any location on the globe is what makes remote access software your best business partner.

Remote access software gives businesses wings by facilitating meetings, training and presentations. Online collaboration among colleagues is improved by their ability to share information instantly. With this software, a team leader could, for example, offer training and instructions to multiple participants at the same time. Where staff is in different locations and you need to them to work together, arranging a conference is easy. Most software also allows for instant messaging.

Perhaps the leading reason for the installation of remote software for many people is the savings in both time and money that it makes possible. When you are a busy consultant who has to make physical visits to your clients’ offices, this software takes your work to a new level since you are now able to attend to your clients from your office, home or any location in our global village. Since the software enables you access to your clients’ computers, you are able to attend to their problems from remote locations thereby saving you money and travel time. Moreover, it allows you to offer instantaneous solutions making you a more effective worker.

For telecommuters, this software works like magic. When you are out there in the field and need to obtain critical data or company information that could help seal a deal, you will no longer have to wait to go back to the office to get this information. Time is of essence in telecommuting and a deal could be made or lost depending on how efficiently you are able to serve clients.

While there are both free and paid-up versions of remote PC access software, most businesses prefer the latter as they considered more reliable than the free versions. The amounts required to install the software are rather modest when the saving in time is considered. Whatever a company pays for this software is recovered quickly through increased efficiency levels.

Remote PC access software also enables systems administrators to exercise greater control over employees. Since the administrator is able to control any computer in the LAN, he or she is able to decide what information to provide to certain employees and what information to withhold. This improves accountability – should some information end up in the wrong hands, such as the competition, it is easy to know who could have leaked such information.
