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.
