Abstract

See full text

A scheduling system for IP routers is provided. A programmable scheduler for IP routers can support single stage and multistage scheduling. This allows flexible combinations of scheduling and widens dramatically the available QoS solutions to operators. With this kind of scheduling the router can be configured to support almost any known scheduling method or combination. Priority Queuing (PQ) and Deficit Round Robin (DRR) scheduling is scheduling is used according to one embodiment of the invention.
