description Real time multimedia content transmission on the Internet is essential for the most current applications such as voice over IP, video conference, games and web TV. The most popular Internet transport protocols - TCP and UDP - do not suffice when one needs to transmit data from these applications. As a consequence, IETF has been working in new transport protocols that enhance the quality of these multimedia applications. Among all these protocols, DCCP (RFC 4340) is the most effective for multimedia content transmission on the Internet. However, DCCP is not effective in scenarios with many receivers nodes and one sender node. Therefore, this work proposes the Mult(Uni)cast DCCP, a DCCP variant that enables the multimedia data transmission from one to various nodes and supporting non-reliable traffic congestion control. The MU-DCCP uses either multicast or unicast flows according to the network support and data sharing among receiver nodes. The obtained results show that the usage of the MU-DCCP significantly reduces the data congestion in the network while improving the application scalability in terms of the number of receiver nodes.
