INTRODUCTION
A communication network consists of a collection of devices (or nodes) that wish to communicate and interconnect together. The primary objective in any communication network is simply moving information from one source to one or more destination nodes. Based on the techniques used to transfer data, communication networks can be categorized into broadcast and switched networks. In broadcast networks, data transmitted by one node is received by many, sometimes all, of the other nodes. In switched-communication networks, however, the data transferred from source to destination is routed through the switch nodes. The way in which the nodes switch data from one link to another as it is transmitted from source to destination node is referred to as a switching technique. Three common switching techniques are circuit switching, packet switching, and message switching.
