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

T1 speed connections aren't just for large corporations any more. As pricing declines many people are opting for the more reliable and flexible service over a DSL connection. Also, the growing number of bandwidth hungry applications like ASP service, VOIP, streaming video and graphic heavy files are pushing the demand for more reliable connections. So, what does it take to get one of these connections?
Getting a connection isn't as complicated as it was just two years ago. Products have been streamlines and bundled for small businesses to be able to take advantage. While a standard connection was between $1,000 and $2,000 just a few years ago a small business can now find integrated service including both voice and data on a single line for as little as $500! For most companies this is comparable the the price they already pay for DSL service and their phone service. So why not switch?
Switching to a more reliable connection is not only less expensive than a few years ago, the implementation has been streamlined. Companies quote a minimum of 30 days to perform an installation but some can perform the implementation in as few as 20 days! While this is possible with some companies not all companies are capable of this speed yet. Much of the imlementation process is handled by the LEC (Local Exchange Carrier) and is out of the hand of your service provider. With the reduced price and streamlined implementation available you may want to reconsider your current connections and get a large company service at a small company price.
