Chapter 7: Class of Service

To set up scheduling, you need to specify the maximum number of

packets a port should transmit from a queue before moving to the next

queue. This is referred to as specifying the weight of a queue. In all

likelihood, you will want to give greater weight to the packets in the higher

priority queues over the lower queues. Table 2 provides a scheduling

example.

In this example, the port transmits a maximum of 25 packets from Q3,

then 15 packets from Q2, and so forth.
