LDA + TCP-Friendly Adaptation : A Measurement and Comparison Study

In this paper, we present an end-to-end adaptation scheme, called the enhanced loss-delay based adaptation algorithm (LDA+) for regulating the transmission behavior of multimedia senders in accordance with the network congestion state. LDA+ uses the real-time transport protocol (RTP) for collecting loss and delay statistics which are then used for adjusting the transmission behavior of the senders in a manner similar to TCP connections suffering from equal losses and delays. The performance of LDA+ is then investigated by running several simulations as well as measurements over the Internet. Additionally, by conducting simulations, the performance of LDA+ is compared to that of other TCP-friendly congestion control schemes presented in the literature.
