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).
