Bandwidth fine-grained management method based on multi-channel hierarchical flow shaping

Abstract

The invention discloses a bandwidth fine-grained management method based on multi-channel hierarchical flow shaping. The method comprises the steps of calculating a first quantity threshold value of uploaded data packets sent by a base station in each operation period and a second quantity threshold value of downloaded response data packets sent by the base station in each operation period; performing domain division on the interface according to a physical networking structure, and performing interface pipeline division on the interface; making a domain bandwidth strategy for each domain; andperforming bandwidth control, finishing flow shaping by adopting a buffer area and a token bucket, and dividing a data sending channel into a main channel, a sub-channel and a micro-channel. According to the invention, a triple nested channel management mechanism and a hierarchical borrowing mechanism of the main channel, the sub-channel and the micro-channel are used; hierarchical flow shaping is realized; the fine-grained bandwidth management requirement of a user is met; the data transmission characteristic of the base station is fully considered; the shaping and rate increase of data flowduring concurrent service are solved; the stability of data transmission is ensured; the algorithm is simplified; and the use effect is excellent.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a bandwidth fine-grained management method based on multi-channel hierarchical traffic shaping. Background technique [0002] With the development of fiber-to-the-home technology, EPON technology, which combines the simplicity and high penetration rate of Ethernet with the economy of passive optical network structure, has become the mainstream technology of access network; with the rapid development of network multimedia technology, IP Services tend to be diversified, such as IP telephony, e-commerce, video conferencing, video-on-demand, distance education and other multimedia real-time services, and in QoS performance, bandwidth performance indicators are the core indicators; with the development of broadband network technology, how to effectively manage and It has always been a difficult problem to control bandwidth to control the increasingly serious abuse and mi...

AI Technical Summary

Problems solved by technology

[0003] Because in the network of operators or enterprise users, network bandwidth resources are very precious, and the bandwidth management methods currently used are relatively simple, it is difficult to effectively control bandwidth at multiple levels and fine-grained, the network bandwidth resources cannot be rationally utilized, and data transmission is not enough Stable, the speed is difficult to improve, needs to be improved
