In computer networking a routing table, or routing information base (RIB), is a data table stored in a router or a network host that lists the routes to particular network destinations, and in some cases, metrics (distances) associated with those routes.
The information in the Routing Table is used for the host to verify when it helps to transfer a packet to the destination of the packet. While receiving a packet, the host verifies the identifier of the destination host. When a record in the routing table has the same destination, the host gets the identifier of next host and the delay constraint in the Next field and dc field of the routing path, respectively. Thus the host knows the receiver of this packet and the constraint of delay transferring. To guarantee the delay constraint of a packet, the delay time of each transmission should be limited in a certificated duration, namely, delay constraint of the transmission.
Routing protocols are classified in three categories:
•
Proactive: current routing tables for the network are maintained continuously.
•
Reactive: routes are established on-demand when there are data to transfer.
•
Hybrid: combine features of proactive and reactive protocols.
