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

If a full T1 isn't in your budget, you need to consider a fractional t1 line. Why not get all the advantages of T1 even if your not in a market for a full T1? For many people the biggest factor in their decision is reliability and if reliability is critical to the applications you run over your connection you should seriously consider replacing your DSL connection with a fractional T1. DSL is a quick and cost effective method of acquiring high speed bandwidth however it is not intended to support commercial applications or large numbers of users as are T1 connections.

One drawback to fractional T1 service is the price. Even though you won't have a full T1 you will be paying quite a bit more than you did for your DSL connection. This is due to the structure of T1 pricing. 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. This loop is paid in full whether you use a fraction of the available bandwidth or the full 1.5Mbps and therefore your price for a 768Kbps fractional T1 connection will never be half the price of a 1.5mbps full T1 connection.

Although the price reduction is not what you might expect it to be, this may put a T1 in your budget and be a great way to get dedicated service into your building. Once you have fractional service upgrading to full service is easy. Fractional service typically comes in 256Kbps increments from 256Kbps all the way to a full T1 at 1.5Mbps. Find the service that's right for you, but if you are supporting critical services think reliability. Reliability becomes critical when customers or employees depend on your connection for immediate responses. If your customers use your connection to access your databases or your server or the internet then reliability of your connection is critical. If your employees depend on your connections because you host the e-mail server in house or host web servers or ASP type products, your connections is considered critical. A critical connection can be viewed much like a lifeline, without which your business would be negatively impacted.
