UDP协议与TCP协议的对比分析与可靠性改进

鉴于互联网快速发展,计算机网络正逐渐应用到通信网络,以太网在移动通信网络建设中起到越来越重要的作用。目前,实现可靠数据传递的方法主要采用传输控制TCP协议或者SCTP简单流传输协议。传输层的TCP协议和UDP协议各有特点和优势,在与以太网的结合过程中,通过详细的对比分析,UDP更加符合以太网的传输环境,不过由于UDP是非可靠通信协议,直接将其使用在对可靠性要求非常严格的电信领域还需要对其进行改造。结合TCP和UDP的优点,提出了RUDP协议,并做了简单介绍。

Contrast Analysis of UDP and TCP and Improvement of UDP in Reliability

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.
