基于双网的高可靠UDP通信方法

High reliable UDP communication method based on dual network

为满足通信系统对可靠数据通信的需求,针对一种基于双网的高可靠UDP通信方法进行研究。在分析双网拓扑结构的基础上,介绍双网可靠UDP通信的实现方法。采用请求/应答机制建立和释放传输任务,通过接收端的反馈信息对传输网络状态进行实时的监控;网络故障时,根据最短路径原则选择最优传输网络重新建立传输任务,实现网络切换的实时性和无缝性;采用编号差值法,对接收数据进行排序、重传和过滤,保障数据的有效性、可靠性和唯一性。该方法具有低延时、高可靠、实施方便、部署简单等特点。

To improve the reliability of data communication,a reliable UDP communication method based on dual network was researched.On the basis of dual network topology analysis,a dual network reliable UDP was described in detail.A request/response mechanism was used to establish or release a transfer task,and feedback information received from transmission side was applied to monitor the network status.When a network failure occurred,a shortest path principle was used to select the optimal transmission network and re-establish the transfer tasks,achieving real-time and seamless network switching.According to the number difference method,received data were resorted,retransmitted or filtered to ensure data validity,reliability and uniqueness.The results show that this method is characterized by low latency,high reliability,convenient implementation and simple deployment.
