Embodiment Construction

[0045]Aiming at the problems of high parallel overhead and limited performance in the existing multi-core CPU-based HQoS implementation method, the embodiment of the present invention provides a multi-core CPU-based HQoS implementation method. The process of the method is as follows: figure 2 shown, including:

[0046] S20: After each CPU classifies the received messages in parallel according to the first scheduler corresponding to the highest-level queue to which they belong, and distributes various types of messages to the queues of the corresponding first scheduler, where A scheduler's queue is locked before dispatching messages and unlocked after completion.

[0047] When classifying packets, each CPU can process them in parallel.

[0048] When each CPU distributes messages to the queues of each first scheduler, multiple CPUs may distribute messages to a first scheduler queue at the same time, so it needs to be locked before the message is distributed and unlocked after ...

Abstract

The invention discloses a method, device and network equipment for implementing HQoS based on a multi-core CPU. The method includes: after each CPU parallelly classifies the received packets according to the first scheduler corresponding to the highest-level queue to which they belong, The class messages are distributed to the queues of the corresponding first schedulers, wherein the messages are locked before distributing the messages to the queues of each first scheduler, and unlocked after the end; Set a rule to schedule the packets in the queue of the corresponding first scheduler step by step, and distribute the scheduled packets to the queue of the corresponding second scheduler according to the destination port. Locking before distributing the message in the middle, and unlocking after the end; according to the port setting rules included in the corresponding second scheduler, the messages in the queue of the corresponding second scheduler are scheduled and sent step by step. This scheme reduces parallel overhead 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...
