As the VPN market approaches maturity at a brisk pace, vendors have been forced to rethink the tradition identity of their IP Security-based technology for letting users securely access enterprise resources via the Internet. Most large companies in need of linking their offices together have done so on frame relay networks. Although frame is still a useful product many users have found that the reduced cost of VPN gives them an attractive alternative.

'During the last 18 months, vendors have pushed VPN technology into different devices, have lessened the distinction between VPN and firewall products, and have demonstrated a strong willingness to deviate from standardized technology to meet corporate remote access requirements. VPN services now come bundled with many dedicated services and several service providers are using VPN products as a loss leader so they can sell circuits. When investigating the use of VPN products make sure you speak with a professional who can guide you through the strengths as well as the weaknesses of the product. While it is a cost reduced alternative to frame it is a different product and should be thoroughly researched.

One of the advantages of a VPN is that internet access is not based only on the hub and spoke layout. The users away from the hub are able to access the internet through their own connection rather than going through the hub and creating a bottleneck. Users will only need to connect through the hub if they need to access information from the central database. When researching alternatives such as VPN, like always, we recommend you consult with a professional and not just a salesman for a VPN company. Make sure the individual you speak with is unbiased and will give you the strengths and weaknesses of each product. We recommend one of the brokers at T1 price for unbiased recommendations of multiple carriers.

A t3 connection is a point-to-point dedicated line that provides 672 64-Kbps voice or data channels or in other words 28 T1 lines. A T3 is used to transmit digital signals at 44.736 megabits per second and has enough bandwidth to transmit full-motion real-time video, and very large databases over a busy network. A T3 line would be installed as a major networking channel for a large corporation or university with high volume network traffic.

When you need more capacity, you often have to buy it in the next available increment, which may end up costing more than you want or can afford to spend. Worse yet, with current, "bursty" application requirements, the need for additional bandwidth can often be as temporary as it is critical. By providing flexible capacity, or "bandwidth on demand," service providers can help customers deal with variations in traffic, and with avoiding a high fixed monthly payment. True bandwidth-on-demand services should allow for a wide range in capacity.

Although anybody can purchase a burstable T3, this type of connection can be costly, even as costly as a full 45Mbps connections. Burstable lines can be found at their lowest cost at a colocation facility. At a colocation facility, or "colo", many users share a large OC3 or OC12 pipe. As a customer you will not have to pay for a the fixed cost of such a large pipe, but will have the benefit of being able to burst up to very high speeds if necessary. If you need the reliability of a large pipe fur busty traffic but don't have the capital consider a colo. If you have a steady volume and are consistent, you may consider keeping services in house and going with a T3 connection. Whether you're considering a colocations facility or a T3 to the door, make sure you use a broker to help guide you through the providers and plans available.
