A Linux implementation of MulTFRC

The use of multimedia streaming on the internet is increasing. With this the need for new protocols is created. The Datagram Congestion Control Protocol (DCCP) can support this better than other existing protocols like Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). To keep the multimedia streaming from causing congestion within the net- work, the use of congestion control algorithms is required. The imple- mentation of DCCP in the Linux kernel supports two such algorithms. The one concerning this thesis it called TCP-Friendly Rate Control (TFRC). This thesis will implement a new congestion control algorithm called MulTFRC. MulTFRC is made to provide a number of cumulative TFRC flows. This re- lieves application of complexity concerning the use of multiple TFRC flows to provide prioritization for its services. This thesis followed the steps of the internet draft "MulTFRC: TFRC with weighted fairness" to implement MulTFRC. Evaluation of the implementation showed that the algorithm works, but that there exists flaws in the Linux kernel implementation of DCCP.
