Routers do more than routing Routing Table Access List Queuing Prioity Accounting Data Cache Packet Switching Tasks Security Tasks Queuing Tasks Accounting Tasks Figure 19: Basic steps in Routing Earlier we have looked at the routing step, but today much of the excitement is in the details of the other functions. For example, in order to support various QoS features you might want to use more sophisticated queue management: Weighted Round Robin, Fair Queuing, Weighted Fair Queuing, Random Early Detection (RED), Weighted RED, … .
