Executive Summary

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.
