摘要
提出了一种根据流类型进行不同优先级处理的主动队列管理机制。该机制通过利用流类型特征以及已经被丢弃的分组信息来加强对各种类型流的识别,进行相应的惩罚或保护。仿真结果表明,在不保持流的状态下,该机制对非TCP友好流有较强的区别和控制能力,对脆弱流也有一定的保护作用,因此实现了较为公平的带宽分配。
This paper proposes a new active queue management mechanism which gives different priority to each flow based on the type of flow. The information about the type and character of the flow and the packets that have been dropped are collected, and then being used to identify the priority of the flow, decide whether to punish the flow or protect it. The simulation results show that without holding the state of each flow, the method given in this paper can punish the non-adaptive flow, while at the same time protect the fragile flow, so in the end reach the goal of bandwidth fairness.
