For example, imagine if there are two sockets established between server and client processes (due to multiple ips or roaming, time lags, etc.), then in theory, request received from one socket could be responded through another socket. From application pov it doesn't need to care about the socket. We can do this over TCP, but connection-oriented nature of TCP makes this weird.
