Reliable Transmission Design Based on UDP Timeout Retransmission and Fast Verifications
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 se-quence 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 pro-posed in this paper can accurately realize the transmission of UDP network data,improve the correctness and reliabili-ty of UDP network data transmission,and realize real-time and Reliable UDP data transmission.
