摘　　要：基于UDP以太网传输协议实现的应用程序是一种无连接、传输不可靠的通信应用,UDP网络传输过程中经常会出现丢包、错包、乱序等一系列的问题,为提高网络UDP通信中数据传输的正确性和可靠性,提出了基于UDP超时重传与快速校验的可靠传输设计。设计方法对UDP应用层数据增加了传输控制协议内容,主要有信源、信宿、类型、重传次数和数据校验位等数据项,实现对UDP传输的数据包内容进行正确性校验,保证传输过程数据包的顺序性、正确性和可靠性。经实验数据验证,提出的设计方法能够准确无误的实现UDP网络数据的传输,提高UDP网络数据传输的正确性和可靠性,实现实时、可靠UDP数据传输。The application program based on UDP Ethernet transmission protocol is a communication application with no connection and unreliable transmission.A series of problems such as packet loss,wrong packet and out of sequence often occur in the process of UDP network transmission.In order to improve the correctness and reliability of data transmission in network UDP communication,this paper proposes a reliable transmission design based on UDP timeout retransmission and fast verification.This design method adds the content of transmission control protocol to UDP application layer data,mainly including data items such as source,sink,type,retransmission times and data check bit,so as to verify the correctness of UDP transmitted data packet content and ensure the sequence,correctness and reliability of data packets in the transmission process.The experimental data shows that the design method proposed in this paper can accurately realize the transmission of UDP network data,improve the correctness and reliability of UDP network data transmission,and realize real-time and Reliable UDP data transmission.
