Net, the System.Net.Sockets namespace provides a managed implementation of the Windows Sockets (Winsock) interface for developers who need tight control over network access. All other network access classes in the System.Net namespace are built on the socket socket implementation, such as the TcpClient, TcpList
UDP differs from TCP in socket programming
UDP is a non-connected transport, so there is no need to establish a connection and no need to listen for a client to send a connection request ( Specifically, UDP does not require listen () and accept () in socket programming)
UDP uses a datagram-oriented approac

It features simplicity and quickness. Compared with TCP, UDP does not need to establish a connection (connect and accept functions are not require

we have discussed TCP servers and clients in the network. In fact, UDP servers and clients are also divided into synchronous and asynchronous servers. The biggest difference between UDP and TCP is that TCP is based on connections, while UDP is connectionless. The so-called connection means that when the other party interrupts the service, the other party can perc
Python: udp Network Programming
In python, the Network Program of the c/s architecture of udp protocol written by the socket module is as follows:

Description: Implemented based on the UDP protocol of the Netty 3.9.2 (if you are using a version of 4. X or 5.X, refer to other methods); The logical structure of the program is that the client sends a string of data to the server, which is returned to the client "A". In the game development needs to the UDP packet loss processing, can use the

In this paper, we describe the method of Python transmitting UDP datagram, which is of practical value. Share to everyone for your reference. The specific methods are analyzed as follows:

This paper illustrates the method of implementing UDP datagram transmission by Python, which is very practical. Share to everyone for your reference. The specific methods are analyzed as follows:
Service-Side code:
Import socket
Port = 8081
s = Socket.socket (socket.af_inet,socket. SOCK_DGRAM)
#从给定的端口, from any sender, receive UDP datagram
s.bind (("
Here's an example udp echo server I created from a simple UDP example (originally to help another thread question, now solved ). additionally, it shows how to use select () to poll the socket (with an optional time out ).

2. Bind an interface to all
This function provides an iterative server, rather than providing a concurrent server as a TCP server. There is no call to fork, so a single server process has to deal with all customers. In general, most TCP servers are concurrent, and most UDP servers are iterations.

TCP/UDP are both network programming (sockets) based on the C/s structure of the program.UDP: Non-reliable connection speed, server: Create socket binding IP and port directly from the specified IP and port to receive data without listening; client: Create socket, receive data directly, do not need to establish a connection.s = socket.socket (socket.af_inet, socket.

Before we wrote about the client/server model for TCP, we now write client/server mode on UDP.There are some essential differences between a TCP-written application and a TCP-based application because of the difference between the two transport tiers: UDP is a non-connected, unreliable datagram protocol, unlike the connection-oriented, reliable byte stream provid
