on, which, although the definition of communication protocol protocol is different , but the underlying transmission is the socket used. In fact, a socket can be considered a data channel like a stream stream, which is built between the application side (client) and the remote server, and then the read (receive) and write (send) of the data are directed at this channel. Visible, after the socket object is created on the application or server side, you can use the Send/sentto method to send da

is therefore widely used. Mastering the principle and function of TCP packet package is helpful for us to learn and utilize more application layer applications and technologies such as file Transfer (FTP), remote login (RemoteLogin) and so on. This course design requires that we achieve the following effects: (1) Run as command line: Sendtcp source_ip source_port dest_ip dest_port Where Sendtcp is the program name, SOURCE_IP is the source IP address,

Reference: Linux high Performance Server programming. Swimming doubleThe program is simple: The program uses shared memory to synchronize between processes, because it is only the same time to read shared memory. So no practical to lock. The function of the program is that the server listens for network connections, an

1. Preface: Although it is convenient to write simple web programs in Python, a more complex network program is better than a ready-made framework. This allows you to focus on the logic of the transaction rather than the various details of the socket. The Socketserver module simplifies the task of writing a network service pr
