This document discusses Frame Relay, a packet switching protocol used in wide-area networks. It compares Frame Relay to traditional T-line networks and X.25, describing how Frame Relay supports variable bit rate data transmission using permanent and switched virtual circuits (PVCs and SVCs), congestion control methods like BECN, FECN and leaky bucket algorithms, and address formats like FRAD that allow multiple destinations per interface.
