UDP - Client and Server example programs in Python UDP Overview: UDP is the abbreviation of User Datagram Protocol. UDP makes use of Internet Protocol of the TCP/IP suit. In communications using UDP, a client program sends a message packet to a destination server wherein the destination server also runs on UDP. What’s the Difference Between TCP and UDP? Jul 03, 2017 windows - Why UDP does not show LISTENING in the state The protocol is reliable and requires separate state for each server<>client stream. The connect protocol, initiated with listen/accept, sets up this server<>client connection state. UDP is a connectionless, unreliable datagram, (message) protocol, so no need to listen for new connections - datagrams can come in in any order from any source."

UDP sockets UDP or user datagram protocol is an alternative protocol to its more common counterpart TCP. UDP like TCP is a protocol for packet transfer from 1 host to another, but has some important differences. UDP is a connectionless and non-stream oriented protocol.

listen() marks the socket referred to by sockfd as a passive socket, that is, as a socket that will be used to accept incoming connection requests using accept(2). The sockfd argument is a file descriptor that refers to a socket of type SOCK_STREAM or SOCK_SEQPACKET .

The sockfd argument is a file descriptor that refers to a socket of type SOCK_STREAM or SOCK_SEQPACKET.. The backlog argument defines the maximum length to which the queue of pending connections for sockfd may grow. net - The Go Programming Language Package net provides a portable interface for network I/O, including TCP/IP, UDP, domain name resolution, and Unix domain sockets. Although the package provides access to low-level networking primitives, most clients will need only the basic interface provided by the Dial, Listen, and Accept functions and the associated Conn and Listener
