Frame Relay |
Packet-Switched FRAD, bridges, Routers, - 56kbps, FT1, T1 FRAIDs
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 process is streamlined. There are significant differences that make it a faster, more efficient form of networking. The 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.
The intelligent network devices connected to the network are responsible for the error correction and frame formatting. Processing time is minimized, so the transmission of data is much faster and more efficient.
In addition, Frame Relay is entirely digital, which reduces the chance of error and offers excellent transmission rates. FRADs typically operates at 56 kbps to 1.544 mbps.
