Frame Relay was developed to solve communication problems that other protocols could not: the increased need for higher speeds, an increased need for large bandwidth efficiency, particularly for clumping ("bursty" traffic), an increase in intelligent network devices that lower protocol processing, and the need to connect LANs and WANs. Like X.25, Frame Relay is a packet-switched protocol. But the Frame-Relay process is streamlined. There are significant differences that make Frame Relay a faster, more efficient form of networking. A Frame-Relay network doesn't perform error detection, which results in a considerably smaller amount of overhead and faster processing than X.25. Frame Relay is also protocol independent-it accepts data from many different protocols. This data is encapsulated by the Frame-Relay equipment, not the network.

'Today's LANs and computing equipment have the potential to run at much higher speeds and transfer very large quantities of data. With the diversity and complexity of today's networks, management can be a mammoth task if you don't have the proper tools. Each environment is a unique combination of equipment from different vendors. Frame Relay uses a packet-switching technology, similar to X.25, but is more efficient. As a result, it can make your networking quicker, simpler, and less costly.

Frame Relay sends information in packets called frames through a shared Frame-Relay network. Each frame contains all the information necessary to route it to the correct destination. So in effect, each endpoint can communicate with many destinations over one access link to the network. And instead of being allocated a fixed amount of bandwidth, Frame-Relay services offer a CIR (committed information rate) at which data is transmitted. But if traffic and your service agreement allow, data can burst above your committed rate. Since Frame Relay has a low overhead, it's a perfect fit for today's complex networks. You get several clear benefits: First, multiple logical connections can be sent over a single physical connection, reducing your internetworking costs. By reducing the amount of processing required, you get improved performance and response time. And because Frame Relay uses a simple link layer protocol, your equipment usually requires only software changes or simple hardware modifications, so you don't

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.
