The UDP protocol is used for connection-less, message-based data exchange between two or more systems, treated as peers. One peer can send a message to another peer (unicast), multiple peers (multicast), or peers on the same subnet (broadcast).
NOTE: The UDP protocol does not set up a dedicated end-to-end connection. The communication between the peers is achieved by transmitting information unidirectional from source to destination. It does not allow you to verify if a message reached its destination peer or information was lost on route. The UDP protocol does not provide any concept of acknowledgment, retransmission, or timeout.
