MBLUE(ModifiedBLUE)是一种面向数据流的活动队列管理算法 .它不是使用平均队列长度指示缓冲区拥塞状态 ,而是使用数据报丢弃的频率和队列空闲程度来管理网络拥塞 .探测瓶颈连接早期的拥塞信息 ,通过数据报的丢弃和标记避免拥塞 .它只维护一个先进先出队列 ,以较少的数据流状态信息 ,在不同流之间公平的分配网络带宽 .能够适应瞬时的猝发流 ,能合理控制非TCP数据流 ,又能够保持较短的平均队列长度 ,从而控制、减轻网络拥塞 .通过TCP/IP网络的模拟 ,证实算法在公平的分配网络带宽和降低数据报的丢失率上具有较好的鲁棒性
Instead of using the average queue length to indicate buffer congestion, MBLUE (ModifiedBLUE) is a data flow-oriented activity queue management algorithm that uses the frequency of dropped datagrams and the degree of queue idleness to manage network congestion. Congestion information, through datagram discarding and marking to avoid congestion.It only maintains a first-in-first-out queue, with less data flow status information, in the fair distribution of network bandwidth between different streams.Able to adapt to the instantaneous burst flow, can It can control and reduce the network congestion by controlling the non-TCP data flow and keeping the average queue length shorter.Through the simulation of TCP / IP network, it is proved that the algorithm has more fair distribution network bandwidth and lower loss rate of datagram Good robustness
