Introduction to Frame Relay

Frame relay is a high-speed, packet-switching WAN protocol that connects

geographically dispersed LANs. Frame relay is usually offered by a public

network provider; however, private organizations can acquire and manage their

own frame relay networks as well.

Frame relay is a connection-oriented protocol, which means that it relies on

end-to-end paths between devices connected across the network. It implements

these connections using permanent virtual circuits or switched virtual circuits.
