Networks may have different topologies and different protocols and to connect them we need to set up a conversion or translation service between them: connecting networks. 2 similar networks (same protocol) are connected by means of a bridge whose job is to connect 2 or more segments and control packet flow between them. 2 dissimilar networks (have different protocols) are connected by means of gateway device, which provide assistance to make sure the message flows uniformly in both networks. Network switch links segments of the network to bridges or gateways. A switch that does process data is called a multilevel switch because it will be working at a level 3 processing. Consider the following scenario of 9 packets going from a to b.
