With the quick development of Internet,the computer network is gradually applying to the communication network,while the Ethernet is becoming more and more important in the construction of mobile communication network.By far,TCP and SCTP are still the main methods of reliable data transmission.As transmission layer protocols of ISO,TCP and UDP have different performance and advantages.In contrast with TCP,UDP adapts to the Ethernet better.But UDP is not a reliable transmission protocol,so it is necessary to amend in order to apply to the communication network which is very rigid in reliability.Combining with TCP and UDP,RUDP(reliable UDP) is brought forward and is introduced simply.
