Datagram Congestion Control Protocol (DCCP) is a message oriented transport layer protocol. It implements reliable connection setup, teardown, flow-based semantics, congestion control as in TCP but does not provide reliable in-order delivery of packets. It is because this protocol is used for applications that have strict timing constraints on the delivery of data.
