摘　　要：端到端并行多连接和多路径技术的应用能够提高数据传输的吞吐量,增强数据传输的可靠性,因此成为互联网研究的一个重要内容。一个应用所使用的路径可能会因为网络中存在的攻击而断掉,在失效路径可恢复的情形下,研究了并行多路径传输的可靠性,给出了相应的可靠性模型,得到了此时该应用仍能够成功完成的概率。最后给出了数值仿真,说明了并行多路径数据传输的高可靠性。Technologies of end-to-end multiconnection and multipath transmission can improve throughput and reliability in data transmission,which has become an important research point in Internet.Some of the concurrent paths that an application uses may be broken down by,perhaps,attacks in the network.Reliability of concurrent multipath transfer was analyzed when the failure paths could be repaired after some delay time,and reliability model was proposed accordingly.The probability that an application could be successfully completed was obtained even when there were some failure paths in the network.Finally,numerical examples verify the high reliability of successful data transmission over multiple paths.
