2. DEFINITION Frame Relay is a popular high performance WAN protocol. Frame Relay type of WAN connection - One site to many remote site Very simple network to configure. Lower overhead than x.25 because has fewer capabilities. It uses permanent virtual circuits (PVCs).

3. Technical description

4. Private line design

5. Frame relay network

6. Frame Relay Layers Physical Layer – Frame Relay uses whatever protocol is available. It supports any of the protocol supported by American National Standards Institute (ANSI). Data Link Layer – In this layer the Frame Relay employs a simplified version of High Level Data Link Control (HDLC). HDLC provides extensive error and flow control fields that are not needed in Frame Relay.

7. Structure of a relay frame packet

8. Advantages of Frame relay. Cost Effectiveness Frame Relay provides greater bandwidth, reliability, and resiliency than private or leased lines. Flexibility

9. Disadvantages of Frame relay Slowdowns due to network congestions. Difficulties on ensuring the Quality of Service (QoS).
