Stream Control Transmission Protocol (SCTP) is a transport layer protocol providing reliable transport of data like TCP but with message oriented features like UDP.

It provides some of the same service features of both: it is message-oriented like UDP and ensures reliable, in-sequence transport of messages with congestion control like TCP.
