Abstract
A partitioned packet scheduler comprising a queue manager, an optionally connected rate shaper, and an optionally connected virtual port scheduler is provided. The packet scheduler is for use in a packet switch and has a very simple interface with the remainder of the switch consisting a channel for communicating buffer addresses and internal connection numbers. Very simple interfaces also exist between the queue manager and the rate shaper/virtual port scheduler thereby allowing independent design and update of these components to be performed.
