Abstract

The embodiment of the invention discloses a method and a device for scheduling a queue, relates to the technical field of data transmission, and solves the problem of high delay jittering of the queue in the prior art. The method comprises the following steps of: after scheduling at each time, acquiring a target queue from a queue to be scheduled; if a granularity consumption parameter which corresponds to the target queue is greater than a first threshold value which is pre-set, and the number of waiting queues is zero, setting the target queue as the waiting queue; if the granularity consumption parameter which corresponds to the target queue is greater than the first threshold value and smaller than the granularity consumption parameter which corresponds to the waiting queue, setting the target queue as the waiting queue, setting the original waiting queue as the queue to be scheduled, and scheduling the queue to be scheduled. The invention is applicable to the technical field of deficit round robin scheduling.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a queue scheduling method and device. Background technique [0002] Quality of Service (QoS for short) is a security mechanism of the network and a technology used to solve problems such as network delay and congestion, among which queue scheduling technology is the key technology in QoS. There are many types of queue scheduling technologies. Currently, the commonly used queue scheduling technology for routers is the deficit round robin (DRR) technology based on deficit. [0003] In the DRR technology, the router forms a cumulative share (Deficit) according to the quota granularity (Quantum) and the weight (Weight). For the remaining share of the scheduled queue, the router schedules in turn according to the preset queue order and the accumulated share. The change in the time interval at which adjacent packets in the same queue are scheduled is called delay jit...
