A kind of qos traffic rate limiting system and method

Abstract

The invention provides a QoS traffic rate limiting system and method. The policy management unit receives external configuration requests including request types and speed limit requirements for QoS traffic; when the request type is new, the diversion flow table management unit sends the corresponding traffic diversion flow table on the br-int bridge of the corresponding data plane node, Execute the flow table management unit on the br-qos bridge of the corresponding data plane node and issue the corresponding traffic execution flow table including the speed limit requirement; each data plane node establishes a corresponding Rate limit queue; forward the QoS traffic targeted by each traffic diversion flow table to the br‑qos bridge through the br‑int bridge; put each QoS traffic into the corresponding rate limit queue through the br‑qos bridge for rate limit processing. This solution can support different granularities of QoS flow rate limit, and the rate limit flexibility is high.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a QoS traffic rate limiting system and method. Background technique [0002] The service quality of the virtualized network directly affects the service quality of users in the cloud computing environment, and the QoS (Quality of Service) guarantee capability of the virtualized network has become an important basic service capability in the cloud computing system. In actual use, QoS guarantee generally refers to the guarantee of bandwidth. [0003] As a mainstream product of open source Iaas cloud computing, Openstack has received widespread attention and popularity from the industry, but there is still room for improvement in terms of specific implementation technologies, such as the implementation of QoS bandwidth guarantee of openstack needs to be improved. [0004] Currently, the implementation of QoS bandwidth guarantee in openstack can be a global speed limit for virtual...

AI Technical Summary

Problems solved by technology

For example, limit the overall bandwidth of a virtual machine port directly through libvirt

[0005] However, directly limiting the speed of the virtual machine port will result in too large a granularity of the speed limit, so the speed limit lacks sufficient flexibility.
