UDP

UDP, or User Datagram Protocol enables computer applications to send messages, or in this case referred to as datagrams. These datagrams can be sent to other hosts on an Internet Protocol network without requiring prior communications to set up special transmission or data paths. UDP is most effective in small servers that have an enormous client population. UDP is cohesive to the Transport Layer due to the fact that it is time sensitive and the UDP ensures no delay when packets are dropped. UDP is a minimal message Transport Layer Protocol, unfortunately UDP offers no guarantee to the upper layers of message delivery or retaining the state of any messages that have been sent. Examples of applications that use UDP include real time multiplayer games, voice over IP as well as streaming media
