摘要
针对目前宽带网接入中对用户流量管理和划分带宽等级难的问题,提出了一种基于宽带接入用户角色的流量管理体系结构。研究了Linux下TC模块实现流量控制和带宽分配的原理,设计了一种基于分类队列的规定,通过把特定的网络用户划分到不同的角色,然后再给不同的角色配置不同的流量控制策略和带宽等级的方法,通过在大型校园网上实际测试证明,该方法能根据需要对不同的用户进行有效地流量管理,规范了网络使用行为,使整个宽带网流量趋于平缓并改善了时间响应特性。
Considering the difficult problem of traffic management and bandwidth division in broadband network access, a new architecture of role-based traffic management is proposed, the theory of traffic control and bandwidth allocation base on Linux TC model is also researched. The method which gives special user different role and the tactics of traffic control and bandwidth division according to different role base on classified queue is designed. Experiments in large-scale campus network show that this method has the control ability of traffic management according to different user, it also specify the criterion of network use. The network flow tend to become gently and the character of time response is improved.
