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).
Technical description
Private line design
Frame relay network
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.

Advantages of Frame relay.
• Cost Effectiveness
• Frame Relay provides greater bandwidth,
reliability, and resiliency than private or leased lines.
• Flexibility
Disadvantages of Frame relay
• Slowdowns due to network congestions.
• Difficulties on ensuring the Quality of Service (QoS).
