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

At the most fundamental level, a t1 internet connection is the link from your companies data infrastructure to the rest of the world. A T1 connection is sometimes referred to as a "dedicated service" as the service is delivered to and from the customer premise from the CO (Central Office) without combining it with other traffic. A T1 connections is established by providing a "loop" or wire from the users premesis to the CO where the service provider has equipment. Part of the cost of a T1 is the "loop charge" or the monthly rental fee for the wire that is rented from the local phone company. Once the connection reaches the CO it can access the carriers network and reach any destination.
While understanding the service may be somewhat straightforward, getting the service implemented is not always so easy. Like any business decision, a switch in T1 providers should be properly researched. You probably don't have time to listen to all carriers sales pitches that you should in order to get the best service, however. Consider shopping in real time by using a broker at T1 Price Quote. While a broker is always a time saver in telecom shopping, the creators of Shop4T1.com have made it even easier to shop for T1 service by introducing the first real-time bandwidth and loop calculator.
With real-time information you'll be able to quickly analyze service plans in your area and determine what is right for you. The people at ShopForT1.com have created a system that equalizes the carriers and makes them easier to compare by laying them out side by side and showing the features of each service. Need more help? They also have agents that will assist you free of charge. These agents make their money when you sign with one of the many service providers so you don't have to worry about them pushing you into a contract that you don't want with a carrier that you don't want. Get your price, ask your questions and be certain when you make your choice.
