用户数据报协议(UDP)(中文3000字,英文2000字)
UDP是位于IP上层的两个主要协议之一.它服务于用户的网络应用程序.诸如网络文件系统(NFS)和简单网络管理协议(SNMP)都是使用UDP的网络应用程序.这些服务只不过是与IP的一个接口.UDP是一种无连接的数据报传输服务,不保证传输的可靠性.UDP不与远端的UDP模块保持端对端的连接;它仅仅是把数据报发向网络,并从网络接收传来的数据报.数据报在传给IP之前被UDP加上了两个值.一个是基于端口的应用程序间的多路信息,另一个是校验和以保证数据的完整性.

外文原文
UDP is one of the two main protocols to reside on top of IP. It offers service to the user''s network applications.
Network applications that use UDP are: Network File System (NFS) and Simple etwork Management Protocol (SNMP). The service is little more than an interface to IP.
UDP is a connectionless datagram delivery service that does not guarantee delivery. UDP does not maintain an end-to-end connection with the remote UDP module; it merely pushes the datagram out on the net and accepts incoming datagrams off the net.
UDP adds two values to what is provided by IP. One is the multiplexing of information between applications based on port number. The other is a checksum to check the integrity of the data.
