User Datagram Protocol
Introduction
------------
This User Datagram Protocol (UDP) is defined to make available a
datagram mode of packet-switched computer communication in the
environment of an interconnected set of computer networks. This
protocol assumes that the Internet Protocol (IP) [1] is used as the
underlying protocol.
This protocol provides a procedure for application programs to send
messages to other programs with a minimum of protocol mechanism. The
protocol is transaction oriented, and delivery and duplicate protection
are not guaranteed. Applications requiring ordered reliable delivery of
streams of data should use the Transmission Control Protocol (TCP) [2].
用户数据包协议 UDP
介绍:
用户数据包协议的制定了,在一个内联的电脑网络环境中,电脑之间进行包交换时,需使用的数据包模式。这个协议的前提是IP被用作底层协议。
这个协议提供了一个程序:当应用程序向其他程序发送信息的时候,只需进行微量的协议构造。这个协议是传输向的,所以不保证传递和重发。如果应用需要可靠的数据流传递的话,应该使用TCP。
