摘要
研究AIS网络的容量与拥塞控制,对于维护AIS网络的稳定、设计完善的AIS通信终端有重要的意义;分析了AIS(AutomaticalIdentification System)网络的链路容量,推算了AIS网络信道中通信终端的最大容量,以及该极限容量的变化规律;论述了当AIS网络处于数据链负荷程度危及安全信息发射时的拥塞解决方法,给出了拥塞控制规则的流程图,有效地解决了AIS网络在拥塞时的冲突问题;该算法已用于笔者设计的AIS通信设备,实验表明,该算法能有效维护AIS网络在拥塞状态下的顺利运行,可用于各种AIS设备中。
It＇s important for maintenancing the AIS network and designing a perfect AIS communication terminal that researching the AIS network capacitance and the congestion resolution, The purpose of this paper is resolve the dataljnk congestion of AIS （Automatic Identification System） network, The data link capacitance of AIS is analyzed at first, and then calculates the limit capacitance of AIS network, giving a change rule of the AIS ＇s limit capacitance. After that, the paper discusses the data link congestion resolution when the AIS data link is loaded to such a level that the transmission of safety information is jeopardized, and give a program flow chart of the resolution. The congestion resolution has been used for actual AIS fermi nal which is designed by writers. And it is useful for the AIS netware operation in our experiments.
