Data
Routing
Routing refers to the process
of selecting the shortest and the most reliable path intelligently over which
to send data to its ultimate destination. IP routing protocol makes
the distinction between hosts and gateways. A host is the end system to which
data is ultimately deliverable. An IP gateway, on the other hand, is the router
that accomplishes the act of routing data between two networks. A router can be
a specialized device supporting multiple interfaces connected to a different
network or a computer multiple interfaces (commonly called a
multihomed host) with routing services running in that computer.
