Introduction1, the agreement is equivalent to the mutual communication between the program reached a convention, it provides the structure of packet packets, the mode of exchange, the meaning of inclusion and how the message contained in the analysis.2, the TCP/IP protocol family has the IP protocol, the TCP protocol and the UDP protocol.3. The address used by the TCP protocol and the UDP protocol is called the port number and is used to differentiate between different applications on the same h

1. TCP-based Network Program It is the general process of a TCP-based client/server program: After the server calls socket (), BIND (), and listen () to complete initialization, it calls accept () to block and wait, and is in the listening port State. After the client calls socket () to initialize, call connect () to issue SYN segments and block wait for the server to respond, the server responds to a SYN-
