Table Of Contents Congestion Management Overview Congestion
management features allow you to control congestion by
determining the order in which packets are sent out an interface
based on priorities assigned to those packets. Congestion
management entails the creation of queues, assignment of packets
to those queues based on the classification of the packet, and
scheduling of the packets in a queue for transmission. The
congestion management QoS feature offers four types of queueing
protocols, each of which allows you to specify creation of a
different number of queues, affording greater or lesser degrees
of differentiation of traffic, and to specify the order in which
that traffic is sent. During periods with light traffic, that
is, when no congestion exists, packets are sent out the
interface as soon as they arrive. During periods of transmit
congestion at the outgoing interface, packets arrive faster than
the interface can send them. If you use congestion management
features, packets accumulating at an in
