Gateways

Brouters

Routers

Routers connect two or more networks and forward data packets between them. When data arrives from one of the segments, the router decides to which segment to forward the data.

Even though each of the routers’ connections is to one physical network, that one network could connect to other networks through the use of other routers. Routers can be static and dynamic.

A brouter combines the best of both a bridge and a router. A brouter can act like a router for one protocol and bridge for all the others. Brouters can route selected routable protocols, bridge nonroutable protocols, deliver more cost-effective and more manageable internetworking than separate bridges and routers.

Gateways make communications possible between different architectures and environments. They repackage and convert data going from one environment to another so that each can understand the other environment's data.

A gateway takes the data from one environment, puts off its old protocol stack, and repackages it in the protocol stack from the destination network.
