OS10 includes congestion management tools to raise the priority of a flow by queuing and servicing queues in different ways. The queue management mechanism used for congestion avoidance raises the priority by dropping traffic from lower-priority flows before traffic from higher-priority flows. Policing and shaping provides priority to a flow by limiting the throughput of other flows. You can configure a guaranteed bandwidth percentage by examining for the egress out flows on the queue. For example, if you have identified three different flows which are egressing out of an interface, you can configure the bandwidth ratio for the flows as 3:2:1 which means: • 1st flow-50 • 2nd flow-33.3 • 3rd flow-16.66 The configuration is then: • Bandwidth percent 50 = bandwidth percent 3 • Bandwidth percent 33 = bandwidth percent 2 • Bandwidth percent 17 = bandwidth percent 1 Bandwidth allocation You can allocate relative bandwidth to limit large flows and prioritize smaller flows. Allocate the relative amount of bandwidth to nonpriority queues when priorities queues are consuming maximum link bandwidth. 448 Quality of service
