Problems solved by technology

Generally, unicast queues and multicast queues are managed with different registers. However, the drawbacks of doing so are: since the sum of the speed limits of unicast queues and multicast queues cannot exceed the speed limit of their common parent node, therefore, In the case of unstable unicast and multicast traffic, if the rate limit for unicast queues and multicast queues is limited separately, the bandwidth of one queue may be insufficient, while the bandwidth of the other queue may be redundant. Greatly degrades user experience

Embodiment Construction

[0028] At present, when the user application performs speed limit and Memory Management Unit (MMU, Memory Management Unit) memory allocation, it only considers that the sum of the speed limits of the unicast queue UC and the multicast queue MC cannot exceed the speed limit of their common parent node, for example: It is required that the speed limit of the scheduler with a priority of 7 does not exceed 100M, and the scheduler with a priority of 7 corresponds to a branch node; then, the speed limit allocation is performed on the unicast queue and the multicast queue corresponding to the leaf node under the branch node When setting fixed speed limits for unicast queues and multicast queues respectively, and the sum of the two speed limits does not exceed 100M, for example: limit the maximum speed of unicast queues to 40M and the maximum speed of multicast queues to 60M; There will be such a problem: when the actual service flow is transmitted, if the service flow of the unicast q...

Abstract

The embodiment of the invention provides a hierarchical quality of service queue speed-limiting method. The method includes: initializing a scheduling structure of a cascade port and establishing a multistage scheduling structure; and performing speed-limiting setting of a father node of a sibling node in need of speed limitation according to the multistage scheduling structure. The embodiment of the invention also provides a hierarchical quality of service queue speed-limiting apparatus.

Description

technical field [0001] The present invention relates to the technical field of network equipment, in particular to a method and device for rate limiting of hierarchical QoS queues. Background technique [0002] With the rapid development of computer networks, more and more important data such as bandwidth, delay, and jitter-sensitive voice and images are transmitted on the Internet. In order to provide different promises and guarantees for data transmission performance, currently Quality of Service (QoS, Quality of Service) technology is widely used to ensure the quality of network transmission. [0003] With the expansion of the user scale and the increase of service types, Ethernet equipment is required not only to further refine and distinguish service flows, but also to perform hierarchical scheduling for the transmission of multiple users, services, and flows. Obviously, these applications are difficult to implement for traditional QoS technologies. [0004] In order ...
