| 摘 要： | 针对无线网络高误码率、时延抖动大等特点,提出了一种新的SCTP检测算法一FRTO(快速重发超时),该算法使用了TCP中的基本思想,其主要改进是:①当收到第一个确认信息后,只发送一个新的数据报;②改进了SCTP的慢启动和拥塞避免算法。对算法进行了仿真研究,仿真结论证明了带有FRTO的SCTP在性能上优于现有的Eifel检测机制和复制的最高传输序列号(DHPTSN)检测机制。

| Abstract: | Big delay spikes and higher bit error rates in wireless network, leading to ST, performance of SCTP in wireless network is badly depressed and been extravagant plenty of network resource. Detection algorithm for SCTP are Eifel detection algorithm and DUPTSN algorithm. Their flaws are that Eifel algorithm need 12 bytes at least timestamp to expends data grams of SCTP and DUPTSN algorithm absences functions when ACK losing. The paper advances a new detection algorithm for SCTP, FRTO (fast retransmission timeouts), and processes simulation study simulation conclusion proves that FRTO has higher performance than two in existence. |
