TCP/IP的通讯协议



这部分简要介绍一下TCP/IP的内部结构，为讨论与互联网有关的安全问题打下基础。TCP/IP协议组之所以流行，部分原因是因为它可以用在各种各样的信道和底层协议（例如T1和X.25、以太网以及RS-232串行接口）之上。确切地说，TCP/IP协议是一组包括TCP协议和IP协议，UDP（User Datagram Protocol）协议、ICMP（Internet Control Message Protocol）协议和其他一些协议的协议组。 -TCP/IP communication protocol this part of the brief overview of TCP/IP in the internal structure, to discuss security issues with Internet-related basis. TCP/IP protocol suite is so popular, partly because it can be used in a variety of channels and the underlying protocol (such as T1 and X.25, Ethernet and RS-232 serial interface) on top. Rather, TCP/IP protocol is a set of protocols and IP protocols, including TCP, UDP (User Datagram Protocol) protocol, ICMP (Internet Control Message Protocol) protocol and other protocols of the protocol group.
