HQoS implementation method, device and network equipment based on multi-core CPUs

Abstract

The invention discloses an HQoS implementation method, device and network equipment based on multi-core CPUs. The method comprises the steps that the CPUs arranged in parallel classify received messages according to first schedulers corresponding to the superlative degree queues where the messages belong to, then distribute the classified messages to the queue corresponding to the first schedulers, wherein before the messages are distributed to the queue of each first scheduler, locking is conducted, and after the messages are distributed to the queue of each first scheduler, , unlocking is conducted; according to the setting rules of each degree queue included in the corresponding first scheduler, the messages in the queues of the corresponding first schedulers are scheduled step by step, then the scheduled messages are distributed to the queues of corresponding second schedulers according to a destination port, wherein before the messages are distributed to the queue of each second scheduler, locking is conducted, and after the messages are distributed to the queue of each second scheduler, unlocking is conducted; according to the port setting rules of ports included in the corresponding second schedulers, the messages in the queues of the corresponding second schedulers are scheduled and sent step by step. The HQoS implementation method, device and network equipment based on the multi-core CPUs reduce the parallel cost and optimizes performance.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a multi-core central processing unit (Central Processing Unit, CPU)-based hierarchical quality of service (Hierarchical Quality of Service, HQoS) implementation method, device and network equipment. Background technique [0002] In order to implement finer QoS control for users, user groups, and user groups, network operators put forward HQoS proposals. The implementation process of HQoS can be divided into two stages: the first stage is classification, which classifies the received packets. After classification, the user queue, user group queue, destination port queue, priority and other information to which the packets belong can be clarified; The second stage is scheduling. The classified packets are scheduled into, discarded, and out of the queue, and finally achieve the expected QoS effect. In the scheduling phase, commonly used is as figure 1 The four-level...
