Abstract
A method of fairly and efficiently scheduling transmission of a packet from a plurality of sessions onto a network is presented. The method includes providing an input having a plurality of sessions, grouping the sessions into a plurality of classes, scheduling the classes with first level schedulers associated with one of the classes, scheduling the outputs of some of the first level schedulers with a second level scheduler, and prioritizing among the output of the remaining first level scheduler(s) and the output of the second level scheduler to provide an hierarchical scheduler output. The scheduler accepts traffic types at its input, and provides an output suitable for scheduling cell based traffic such as Asynchronous Transfer Mode (ATM) network traffic.
