frame relay protocol architecture

Destination 2. Frame Relay is an industry-standard, switched data link layer protocol that handles multiple virtual circuits using High-Level Data Link Control (HDLC) encapsulation between connected devices. for the access link and backhaul link, type-1 relay can be further distinguished into inband relay and outband relay. Frame relay is actually a cross between ISDN (128 kbit / s) and asynchronous transfer mode (ATM), operating on approximately the same principles as frame relay, only at speeds from 155.520 Mbit/s to 622.080 Mbit/s.
