Like most telecommunications services DS3 prices (commonly known at T3) have been falling for the last few years. This is due to several factors. Competition has been heating up since deregulation in 1996. The number of companies offering service has exploded. With more competition in the marketplace service providers have to reduce their prices to attract customer and keep them from going to competitors. Service providers are desperate to keep margins but even more desperate to keep adding customers. This competetive arena has created a buyers market for DS3 lines and pricing is as favorable as it has ever been!
The soft economy and crash of the stock market has also contributed to the reduction in ds3 price. Since the peak of the market in 1999 many companies have gone out of business and no longer require service. This means there's a smaller pie available and there are plenty of telecom providers trying to get their share. Once again, the buyer is in control and can shop until he or she finds the price that is right for them.
A final reason for the reduction in DS3 pricing is the fact that equipement costs and the cost of supplying the bandwidth have decreased. This means that companies can supply the bandwidth at a lower cost. As bandwidth usage continues to increase as a result of bandwidth hungry applications like video on demand and graphic heavy applications the price of bandwidth will coninue to drop. The only factor that seems tlikely to inhibit prices from falling much further is the "last mile" or the connection from the users premise to the service providers' POP (Point of Presence), but we'll save this issue for another article. Until then, enjoy those affordable DS3's and good luck finding a price that's right for you!

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
