What is DCCP (Datagram Congestion Control Protocol)?

Datagram Congestion Control Protocol (DCCP) is a message-arranged transport layer protocol. DCCP gives an approach to gain access to congestion-control mechanisms without carrying out them at the application layer. A DCCP association contains affirmation traffic as well as information traffic. DCCP has the alternative for extremely long sequence numbers comparing to a packet ID, rather than a byte ID as in TCP.
