Its network ranges from 5 to 50 km. In Frame Relay terminology virtual connection lines are known as Virtual Circuits (VCs). information frame, supervisory frame or unnumbered frame. A transport layer can offer applications connectionless service or connection-oriented service between two processes. By using our site, you In X.25, in telephone network modems and in wireless communication systems, reliable node-to-node communication is implemented at lower protocol layers. First of all, it helps in reducing the cost of internetworking, as there is considerable reduction in the number of circuits required and the associated bandwidths. Second, it helps in increasing the performance due to reduced network complexity. It supports all standard physical layer protocols. There are two types of VCs; PVCs and SVCs. 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. TEI ; SAPI ; CR ; none of the above ; 2. Difference between of Frame Relay and X.25 : Attention reader! Frame relay is a packet-switching telecommunication service designed for cost-efficient data transmission for intermittent traffic between local area networks ( LANs ) and between endpoints in wide area networks ( WANs ). Frame Relay does not support Hop-to-Hop error and flow control. Please write to us at [email protected] to report any issue with the above content.
