Adaptation scheme based on network testing and performance analysis

  • In packet-switched IP networks, congestion perhaps is unavoidable. Therefore, it is necessary to perform congestion control for real-time multimedia service. Usually, loss rate is considered as the sign of the network congestion and AIMD is the adjustment scheme. It is difficult to obtain the optimal performance, because the parameters in AIMD scheme are fixed. An adaptation scheme TITD (testing increase and testing decrease) based on network status was proposed. When the network is in congestion, sending rate is reduced to the receiving rate obtained at the receiver. When the network is idle, the additive rate is according to the RTT. TITD is adaptive to the network status, and is superior to AIMD (additive increase and multiplicative decrease) in TCP-friendliness and rate oscillation.
