FLAGS: Delimits the beginning and end of the frame. 33-45. Frame Relay is. Since Frame Relay is protocol independent, it can process traffic from different networking protocols like IP, IPX, and SNA. In many cases, Frame Relay is more efficient than X.25, the protocol for which it is generally considered a replacement. Typically, these applications include data transfer, CAD/CAM, and client-server applications. The need for network addressing using Layer 3 is reduced because many of the link architectures are based on point-to-point circuits or private networking techniques. Note that the SVC service is not currently implemented. Network Layer : At this channel, B-channel has different options in connecting to circuit either circuit-switched, packet-switched, frame relay, or ATM networks.
