A new congestion control algorithm for Datagram Congestion Control Protocol (DCCP) based real-time multimedia applications

In recent times, the applications like streaming audio-video, Internet telephony and multi-player online games are the most prevalent in the Internet world. So, it becomes a great concern to carry out these applications effectively and efficiently. These applications prefer timeliness in packet delivery to reliability. TCPs reliability through packet re-transmission and abrupt rate control features are unsuitable for these applications. As a result, these applications prefer UDP as the transport layer protocol. UDP does not have any congestion control mechanism which is vital for the overall stability of the Internet. For this reason, a new transport layer protocol Datagram Congestion Control Protocol (DCCP) has been introduced which is suitable for these applications because of its exclusive characteristics. But the congestion control algorithm of DCCP seems a little bit faulty as they have some limitations. This paper describes another one congestion control algorithm for DCCP.
