Abstract
A system maintains sub-queues used for storing packets. A respective packet is enqueued into a sub-queue and dequeued by a scheduler. A virtual time associated with the respective packet is based on a current sub-queue virtual time corresponding to a previously enqueued packet in the sub-queue. The scheduler tracks a global virtual time based on dequeuing packets from the sub-queues and by advancing the global virtual time in response to completing a scheduling round. The system inserts a packet into a sub-queue which is previously empty. In response to a virtual time associated with the sub-queue being earlier than or equal to the current global virtual time, the system schedules the sub-queue before the non-empty sub-queues. In response to the virtual time associated with the sub-queue being later than the current global virtual time, the system schedules the sub-queue for forwarding packets after the non-empty sub-queues.
