... During the life of the TCP/IP protocol suite three transport layer protocols have been designed: UDP, TCP and SCTP. The User Datagram Protocol (UDP) is the simplest of all three protocols. UDP does multiplexing and de-multiplexing It also does a type of error control by adding a checksum to the pack ...
