Frame Relay and Packet-Switching Networks

Principle purpose of this lecture is to describe on Frame Relay and Packet-Switching Networks. Packet-Switching Networks includes: Switching Technique, Routing and X.25. Frame Relay Networks includes:  Architecture, User Data Transfer and Call Control. Packet-Switching Networks are one of the few effective technologies for long distance data communications. Frame Relay Networks are designed to eliminate much of the overhead in X.25.
