4 . a formula for calculating receiving buffer length was proposed , based on the analysis and research on network parameters , such as jitter , average speed and packet loss fraction 4 .在分析研究延时抖动、平均速率和丢包率等网络参数的基础上,给出客户端接收缓冲区长度估算公式。
Because of the limit of network resource ( link capacity , buffer length of network node ) and the uncertain of traffic in networks , it should not be avoided that network congestion occurs , and congestion control becomes one of the key technologies in atm networks 由于网络各类资源(信道容量、节点中缓存器容量等)的有限性和网络中各种数据流的不可确定性,不可避免地导致了网络拥塞的产生,使得拥塞控制成为atm网络亟待解决的关键技术之一。
In the proposed method , the controller takes the buffer length as congestion indication , takes sources quality and bandwidth utility as object function so as to learn on line . as the controller outputs , the coding rate for input traffic sources and the corresponding user percentage are used to adjust the cells " arrival rate to the multiplexer buffer . compared with the previous method where cells " arrival rate is tuned only by the encoding rate and the encoding rates for all input traffic sources are regulated in a body , the proposed method guarantee that the quality of cells are optimal while cell loss rate is minimized , which means quality of service is guaranteed 在该方法中,拥塞控制器以缓冲区大小信元作为拥塞指示,以信源质量和带宽利用率作为目标函数进行在线学习,控制器输出包括信源编码率及其对应的用户数在全部用户中所占的百分比,即根据信源编码率及对应的用户百分数调整信源输入流,从而克服了以往拥塞控制方法中仅仅调整编码率带来的对所有信源进行整体调整的缺陷,使控制系统在信元损失率最小情况下确保信源输入流质量最高,从而有效地利用了网络带宽。
