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 some people may enjoy a trip to the local shopping mall, shopping for telecommunication services like a T1 line has never been fun. If you happen to be looking for a dedicated voice line you may call the local phone company. Chances are you'll be passed around to three or four different people who can't handle your request for a T1 line. When you finally speak with someone who can answer your questions you'll go through a litany of questions that don't get to the point of your call which is, "How much do I have to pay".
A step up from a call to the local phone company is the use of a broker or agent. An independent agent can help reduce the number of phone calls by asking you the questions once and searching through multiple providers to get the service that is right for you. The agent helps steer clear of the bias you will receive when speaking with one vendor as the agent will be paid no matter which service you choose. If you happen to be searching for a dedicated voice T1, the agent will give you quotes for dedicated voice T1's for multiple service providers. Still, the agent has a shortcoming in that there is typically a delay between the time you have your conversation and the time you get your information. This can take a day or two.
Why not have the best of both worlds? An agent who carried no bias for one particular carrier AND immediate feedback! While this was not possible a few months ago, we have found a T1 line provider than can offer real-time quotes through its agents. A real time quote give you information NOW. There is no waiting to find pricing. Simply enter your information and compare pricing immediately. Real time pricing will do for telecommunications shopping what Expedia and Travelocity did for travel. So why wait? If you're searching for a T1 line make sure you use a broker that can help you with your search in real time.
