public class WFQScheduler

extends DiffServPacketScheduler

In weighted scheduling, weight for each queue is allocated, and the relative portion of the bandwidth is allocated to the queue according to its weight. DiffServPacketScheduler also configures the DataLinkMapping of the dispatched DiffServ packet from queue. Currently, MPLS LSP or usual IP packet forwarding can be configured as DataLink for DiffServ packet flow.
