【摘要】 在基于域结构的P2P计算网络环境下,针对RED(Random Early Detection)队列管理机制不能完全保证各流量公平共享瓶颈带宽进行改进,运用窗口滑动技术,根据网络流量状态,动态地设置阈值参数mint,maxt和maxp,使队列变化随网络流量变化动态调整,实现了一种Optimized-RED队列管理机制.仿真分析表明:Optimized_RED队列管理机制能有效地保证各连接流量公平共享网络瓶颈带宽,平滑网络瓶颈的阵发流.更多还原

【Abstract】 We proposed a new mechanism called Optimized_RED to improve the performance of queue management of P2P network.Under the RED(Random Early Detection) mechanism for queue management,bandwidth can not be allocated fairly for each flow.The Optimized_-RED mechanism applied sliding window,and sets thresholds dynamically,such as min_t,max_t,max_p,according to the network traffics,and adapted queues to network traffics.Numerical simulation shows that the Optimized_RED mechanism for queue management can allocate fairly the bottleneck bandwidth of network for each connection and can smooth the burst flow of bottleneck network.更多还原
