| 摘 要： | 队列管理机制是实现网络拥塞控制的一项重要技术,以往采用的大多都是被动的队列管理机制,而主动队列的管理是根据网络结点的队列长度的变化进行提前丢包,对网络的拥塞进行预先通知,从而减少和避免网络拥塞,提高服务质量.为了对主动队列管理机制进行研究,对IEFT推荐的RED算法作介绍,与传统的被动管理机制Droptail作比较,并且通过网络仿真器NS2对算法进行模拟与分析,指出算法的优缺点,为进一步研究AQM算法提供依据.

| Abstract: | Queue management plays an important role in network congestion control.Active queue management(AQM) is an algorithm that drops packets ahead according to the variation of queue length of network nodes and notifies network congestion in advance to reduce and avoid congestion,improves quality of service(QoS) of network.In order to study AQM mechanism,this article introduces RED algorithm which was recommended by IEFT.Droptail which is a traditional passive queue management algorithm was compared with it,also ... |
