While a UDP datagram not a "connection" in the TCP sense. You often send a packet via UDP from a port on one machine, to a different port on the same or different machine. If one of those ports changes, then it effectively "breaks" the connection. Since you are no longer getting data on the port you expect to receive it from. So while a pair of UDP ports are not a "connection", it is often a useful abstraction to treat them as one.
