​ Golang realizes UDP protocol connection and communication between client and server.

Let's first talk about the concept and function of UDP. UDP is a user Datagram protocol, a simple Datagram-oriented transport layer protocol. UDP does not provide reliability, it just sends datagrams that applications send to the IP layer, but there is no guarantee that they will reach their destination. Because UDP does not need to establish a connection between the client and the server before transmitting the Datagram, and there is no mechanism such as timeout retransmission, the transmission speed is very fast. So let's talk about how to realize the UDP protocol connection and communication between the client and the server in the go language environment.

Server side

Client

UDP protocol does not distinguish between server and client concepts, here is mainly easy to understand, start the client, connect successfully, output hello client!
