TCP-friendliness Analysis and Evaluation for TCP-like IVS Flow Control Algorithm

TCP-like IVS flow control algorithm provides better stability and lower vibration in data transmission than its predecessor IVS (INRIA videoconferencing system) flow control algorithm. The inferior performance of TCP-like IVS TCP friendliness is shown in this paper through three sets of deliberately designed experiments. Through both theoretical analysis and simulation results the implication behind experiment results are identified and several improvement measures are further suggested. Work in this paper has provided a base ground for the in-depth study on how to provide QoS guarantees for videoconferencing system on the Internet.
