摘要
研究了具有用户数据报协议(user datagram protocol, UDP)数据流干扰和不确定项的TCP/AQM网络拥塞控制问题.首先考虑由丢包率范围而导致的输入饱和的问题,从而对丢包率进行限制.其次,利用模糊逼近的方法处理系统中的干扰和不确定项.为节约网络资源,引入事件触发机制,结合输入饱和、模糊逼近以及Backstepping技术,提出了一种主动队列管理算法,不仅可以使队列长度跟踪到期望队列长度,而且减少了触发次数,节约了网络资源.最后,仿真验证和分析表明了所提方法的有效性和优越性.
The TCP/AQM network congestion control problem with user datagram protocol(UDP) data flow interference and uncertain terms is dealt with. Firstly, the problem of input saturation due to the range of packet loss rate is considered to limit the packet loss rate. Secondly, the fuzzy approximation method is used to deal with the interference and uncertain items in the system. In order to save network resources, an event trigger mechanism is introduced. Combining the input saturation, the fuzzy approximation and Backstepping technology, an active queue management algorithm is proposed, which can not only track the queue length to the expected queue length, but also reduce the numbers of triggers and save network resources. Finally, simulation verification and analysis show the effectiveness and superiority of the proposed method.
