Python network programming-UDP implementationI. Introduction: Python udp is connectionless, without three-way handshake of TCP, error retransmission mechanism, sending only sending, receiving only receiving, the efficiency is higher than TCP, used in places where the data frame is not high, for example, video and audio transmission II.

Because the company is using VMware virtualization technology, each time the virtual machine to allocate a connection to the external network IP address, in addition to the company scale, the new people also need to assign IP address, it is easy to cause the IP address of the bad and IP address conflict,So we decided to use a script to troubleshoot the idle usage of IP, reduce the time cost of operations, and less IP collisions:The script reads as fol

First, Introduction:Python UDP is no connection, no TCP three handshake, error retransmission mechanism, hair, just send, collect, efficiency than TCP high, applied to the data frame is not high, such as video, audio transmissionSecond, the realization process:The server-side process is as follows: 1. Creating a UDP socket 2. Bind an interface to allow the client to connect 3. Acceptance of data The client process is as follows: 1. Create a socket 2. Send

request handler class.Next you have to instantiate a server class that, during instantiation, needs to pass in the service-side address and the class of the request handle.3.Then Call the Handle_request () or Serve_forever () method of the server object to process one or many requests.Then, execute the handle_request () or Serve_forever () method of the server object to process one or more requests.4.Finally, call Server_close () to close the socket.Finally, execute the Server_close () method t
