  • 摘要:

    电力广域保护系统从点到点通信逐步走向网络化通信, 如何在拥塞状态下保障业务的实时性和可靠性, 成为亟待解决的问题. 针对传输控制协议(Transmission control protocol, TCP)不能保障实时性以及用户数据报协议(User datagram protocol, UDP)不能保障可靠性的问题, 本文提出一种联合应用层纠错、检错和重发机制的UDP传输方案, 在提供低时延传输服务的同时也能保障报文的可靠性. 考虑到算法的复杂性, 选择本原BCH (Bose-Chaudhuri-Hocquenghem)码作为纠错编码算法, 设计了编码分组方法, 并通过实验验证了分组方法的正确性; 对增加纠错机制后的报文实时性进行了理论分析和仿真验证; 为了解决突发误码和丢包情况下的可靠性问题, 进一步设计了应用层检错和重发机制, 并分析了时延. 分析表明, 在应用层增加本文所设计的纠错、检错和重发机制后增加的时延几乎可以忽略不计. 最后给出了所提方法的联合应用算法, 并进行了可靠性分析, 结果表明本文方案的可靠性高于其他UDP传输方案.
