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

Why shouldn't shopping for a dedicated internet service be as simple as shopping for a plane trip to Hawaii? In the past the process of getting pricing for dedicated internet service has been anything but simple but that has just changed. Today getting a t1 line price is as simple as entering your information and hitting "enter". With Geoquote software brokers are now offering real-time T1 prices just like you had hoped you could get when you started your search.
Geoquote is a software recently released that allows brokers to give real-time pricing to those seeking service. The software is doing for the telecom industry what Sabre did for the travel industry. In the 60's AMR, the parent company of American Airlines created a software and then began licensing it to the public. This software backed by massive databases was spun off in the form of "Sabre" which owns Travelocity and licenses this software to travel brokers and websites.
If the creators of Geoquote follow the same path as Sabre, this software will be the industry standard and brokers will have to use this software to enable their customer to get quotes in real time. While some brokers are able to run a profitable business without giving out real-time informaion these brokers will soon see their profitability reduce as they spend more time gathering information than actually dealing with customers. If you're currently searching for service, make sure you find a broker that uses Geoquote software.
