Bandwidth allocation method and device

Abstract

The invention discloses a bandwidth allocation method and a bandwidth allocation device. The bandwidth allocation method comprises the steps that: access equipment obtains bandwidth allocation command information for a user from a server according to an access request of the user, and determines whether the bandwidth allocation command information is to allocate a fixed bandwidth value to the user; the access equipment determines access information of the user when the bandwidth allocation command information is not to allocate the fixed bandwidth value to the user; and the access equipment determines a bandwidth value after increase on the basis of the fixed bandwidth value preset for the user currently requesting access according to the access information of the user and the bandwidth allocation command information when current residual bandwidth resources satisfy a preset condition, and allocates bandwidth to the user currently requesting access according to the increased bandwidth value. By adopting the bandwidth allocation method and the bandwidth allocation device, the utilization rate of bandwidth resources can be increased, and the actual available bandwidth can be increased for users.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a bandwidth allocation method and device. Background technique [0002] The broadband remote access server (Broadband Remote Access Server, BRAS) system is used to realize the access management of the broadband metropolitan area network. The BRAS system generally includes an authentication client, an access device, and an AAA server. Among them, the authentication client is a client terminal that accesses the BRAS access device through a LAN or a WAN; the function of the access device is to cooperate with the AAA server to control the access of the authentication client to network resources, and prevent the authentication client from accessing network resources before the authentication is passed. During the authentication process, it interacts with the AAA server to complete the identity authentication, authorization and accounting functions of the authentication...

Problems solved by technology

[0005] At present, in the networking based on user package period billing, the amount of bandwidth that can be allocated to each user is a preset fixed value. Specifically, the access device and the AAA server interact with each other for bandwidth allocation of users. The AAA server transmits the user's fixed bandwidth value to the access device. After the access device obtains the fixed bandwidth value, it sends the fixed bandwidth value to the port of the access device used to access the user, thereby determining the bandwidth of the user. limit

[0006] It can be seen that the method of allocating bandwidth to users according to the fixed bandwidth value in the current networking based on user package period billing is relatively simple, but it also brings waste of resources. Users are all online, and most of the time only some users are online, resulting in the bandwidth reserved for offline users not being effectively utilized
