The Control Plane

The control plane maintains the routing table using three techniques: static routing, distance vector routing, and link state routing. As you explore each one in detail, note their advantages and disadvantages. How does each method deal with link and router failures?

One of the objectives of the control plane in the network layer is to maintain the routing tables that are used on all routers. As indicated earlier, a routing table is a data structure that contains, for each destination address (or block of addresses) known by the router, the outgoing interface over which the router must forward a packet destined to this address. The routing table may also contain additional information such as the address of the next router on the path toward the destination or an estimation of the cost of this path.

In this section, we discuss the three main techniques that can be used to maintain the routing tables in a network.
