Note: frame relay is no longer a topic in ccnav3 200-125 exam let’s start this article with the question: why do we need frame relay let’s take a simple example suppose you are working in a big company and your company has just expanded to two new loc. Frame relay, an overview frame relay is a synchronous hdlc protocol based network data is sent in hdlc packets, referred to as frames the diagram below of an hdlc frame may be familiar, since without adding specific definitions of how the address, control and crc is used, the diagram is applicable to ibm's sdlc, to x25, to hdlc, to frame relay, as well as other protocols. Overview frame format virtual circuits data integrity flow control and information rates status polling uses of frame relay reliability overview frame relay is a simplified form of packet switching, similar in principle to x25, in which synchronous frames of data are routed to different destinations depending on header information.
Frame relay is a packet-switched technology which uses routers, bridges or frame relay access devices (frads) these devices are used to convert data into frame-relay packets at 56kbps, ft1, and t1 speeds.
