In telecommunications, a frame relay network is a service used to transfer data traffic between Local Area Networks (LANs) and between end-points in a Wide Area Network (WAN). Frame relay networks utilizes variable-size units or “frames” and leaves error correction data up to the network end-points. This process allows frame relay networks to operate efficiently. With a frame relay network, the network provides a Permanent Virtual Circuit (PVC). Frame relay networks are considered a fast packet technology which means that when an error is detected the error frame is dropped. It is the responsibility of the end point within a frame relay network to detect and retransmit any dropped packets.

Although an outdated technology, frame relay networks are still used to connect LANs to WANs and major backbones. Frame relay networks are not an ideal for voice or video transmissions. However, frame relay networks provide a useful infrastructure for data transmissions. Frame relay networks can incorporate packets from different protocols including Ethernet. Frame relay can have up to a 45 Mbps local loop to a 44.21 Mbps port. Frame relay network service is available from a wide range of telecommunications carriers.
