Frame Relay Virtual Circuits (VCs): PVCs, SVCs, and DLCIs Explained
We’ve already covered the fundamentals of Frame Relay as a WAN encapsulation protocol. This guide goes deeper into the mechanism that makes Frame Relay work: the virtual circuit. Frame Relay provides connection-oriented data link layer communication specifically through virtual circuits, and understanding exactly how those circuits get established, identified, and torn down is what separates...
