4.8 Frame Relay Protocol
Frame relay protocol is provides multiplexing logical data conversations over a single physical
transmission link by assigning connection identify to each DTE devices.
Frame relay also supports PVC and SVC for data transfer between DTE devices. The different between
X.25 and frame relay is frame relay doesn’t have the windowing and retransmission strategies. Also
frame relay is only layer 2 protocol.
DLCI (data-link connection identifier) identifies the logical virtual circuit between DTE and frame
relay switch.
Frame Relay signaling
LMI (local management interface) is responsible for managing the connection and maintaining
status between the CPE devices and the FR switch.
