Distributed link access bandwidth control system

Abstract

The invention discloses a distributed link access bandwidth control system, comprising a network link access kernel calculation module, a distributed node system load balancing scheduling module and a link bandwidth allocation module, wherein the network link access kernel calculation module is used for unpacking and packaging a user data packet of a client received by an access server and providing interface services for an upper layer application of the network link access kernel calculation module; the distributed node system load balancing scheduling module is used for deploying a plurality of access servers in a network environment by adopting the architecture of a plurality of distributed computing nodes; and the link bandwidth allocation module is used for creating a token buffer pool for each user link in the internal memory of the system and allocating a token, and a data packet carrying the token has the authority of arriving at an outlet link. The distributed link access bandwidth control system disclosed by the invention supports the super-large scale network link access, can effectively reduce the system load and increase the overall bandwidth utilization rate of the system and the energy efficiency of the system, and the method is applicable to network environments with super-large scale users and high loads.

Description

technical field [0001] The invention relates to a distributed link access bandwidth control system, which belongs to the technical field of distributed computing and computer network control. Background technique [0002] Modern broadband networks not only require users to provide sufficient broadband link access, but also to support different services such as video, voice, and data at the same time, and to provide personalized services according to different application requirements of users. Judging from the development history and trend of computer technology and network technology, the increasing number of users and network bandwidth requirements make the data calculation and control of the server become the bottleneck of the entire system. Measures such as load scheduling of nodes and bandwidth control of user links can effectively reduce the load of access nodes and improve the utilization rate of network egress bandwidth. [0003] Currently, network link access devic...

Problems solved by technology

In our country, network construction often only focuses on hardware, and usually ignores the operation optimization scheme of the entire system. Therefore, there are still many practical operation problems after the hardware is deployed. The campus network and commercial districts of various universities generally have service nodes. Low computing power, some users abuse network resources, and maliciously consume network bandwidth, resulting in abnormal growth of network traffic, which seriously affects the normal operation and security of the network and the normal network use of other Internet users

[0004] More and more network users access the broadband network, and the links generated by the increased users will inevitably lead to an increase in the computing load of the access server

Although client communication optimization can reduce the computing load of the server to a certain extent, the main source of server load is the data exchange between users and server processing nodes. The effect of server load is not particularly obvious; in addition, the computing power of a single access node can be increased by continuously increasing the bandwidth of the network egress, upgrading the server hardware configuration, or adopting a centralized load balancing scheduling method. However, the above methods Insufficient operability and scalability, still unable to meet the growing demand for load computing capacity of the entire environment
