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

While Dave Letterman may never read this list on his show, we've created a Top 10 list of California T1 Internet Providers. In our review of service providers we considered realiabiltiy, customer support, provisioning and financial stability. In our opinion a top provider of services will have a high rating in each of the catagories. Unfortunately some of the providers we found were regional providers and may not be near you but two of them are so good you may just want to move closer to be on their network!

The top company in our survey was Telepacific. The only downside to this company is the fact that they only offer service in California and Las Vegas. Telepacific received top marks in all four or our categories and is what we recommend most to customers in California. The second carrier in our list was USLEC. Like our fist pick USLEC is a regional player offering services in the south and on the eastern seaboard. USLEC was founded and is run by engineers. These people have a passion for getting it right and keeping their customers happy. Number three on our list is New Edge Networks. New Edge is a national player found predominantly in metro areas. New Edge is large enough to be a strong player but still small enough to treat customers like a small company.

Our number four position goes to Netifice, formerly Epoch. Again, a small Tier 1 player but excellent service nationwide. Number five position goesto ACC Business. Available everywhere in the continental US, ACC used the ATT network exclusively and provides a high level of service. Positions six through ten when in the following order: Telarus, Sprint, Xspedius, PNG, and Megapath. When looking for a reliable provider you should be comfortable with any of these. Make sure you speak to your broker about the strengths and weaknesses of each carrier. While our rankings were based evenly on the four criteria mentioned at the beginning of the article you may decide that some criteria are more important to you than others. Good luck in your search.
