Abstract
A network device receives traffic associated with a network of intermediate network devices and user devices, classifies the received traffic, and allocates the classified traffic to traffic queues. The network device also schedules particular queued traffic, provided in the traffic queues and bound for particular intermediate network devices, using a hybrid weighted round robin (WRR) scheduler where the hybrid WRR scheduler schedules the particular queued traffic according to one of a 1-level WRR schedule, a 1.5 level WRR schedule, or a 2-level WRR schedule. The network device further provides the particular queued traffic to the particular intermediate network devices based on the scheduling of the hybrid WRR scheduler.
