Unlike TCP is a connection-based protocol, UDP is connectionless.
UDP does not establish a connection when sending data. It sends data without confirming receipt or checking for errors, thus there is actually no such connection between the endpoints under the UDP protocol.
As for gnet, the gnet.Conn for UDP doesn't really represent a connection as it does for TCP, it's just an interface providing some useful APIs, so a gnet.Conn is constructed and destructed along with each data transfer while you're working with UDP.
