Packet-switched networks are built on mesh topologies in which multiple paths to a destination exist. The links in the mesh are point-to-point links joined by routers. A path to a destination may go through any number of routers, and the path may change at any time due to traffic problems or failed links. In this environment, there are two possible packet-routing methods:
Setting up paths implies that the network will keep state information, something that was frowned on in the past due to its potential to reduce performance. But with the need for QoS and bandwidth management rising, explicit routing is now important and can be done much more efficiently due to higher-performance devices.
