Fairness of adaptive multimedia applications

We present a scalable scheme called the direct adjustment algorithm (DAA) for adapting the transmission rate of multimedia applications to the congestion level of the network. The DAA is based on the end-to-end real time transport protocol (RTP). Results achieved through simulations and measurements suggest the efficiency of the scheme in utilizing the network resources and decreasing the loss rates. However, with no support from the network, adaptive applications tend to be unfair towards long distance connections and lead to the starvation of competing TCP connections
