What are the features of frame relay?

Frame Relay (FR): Frame Relay (FR) is a packet oriented WAN technology use for connecting remote offices over the internet or WAN. Frame relay provides the dedicated connection called the PVC which is used to form logical end to end links mapped over a physical network.

The features of frame relay are as follow:

(i) Frame relay provides connection oriented virtual circuit service.

(ii) Frame relay can detect transmission errors.

(iii) Frame relay connections are often given a committed information rate (CIR), which provide guarantees that the connection will always support the committed rate or bandwidth.

(iv) Frame length is variable the maximum frame length allowed in the 1600B above.

(v) Frame Relay is a broad band packet switching and has the transfer rate up to 44.6 Mbps.

(vi) Error rate is very low with frame relay using optical fiber as the transmission medium reducing the error check for the overhead and improves the network throughput.

(vii) Frame relay uses variable length frame based asynchronous multiplexing technology therefore it is used for data transmission and not best suitable for voice and video transmission.
