Executive Summary

This paper demonstrates the performance of PERT, a new TCP congestion control, for video streaming. PERT stands for Probabilistic Early Response TCP. As a delay based protocol, it measures the delay at the end host and adjusts the congestion window accordingly. As the NS-2 simulation results show, the late packet of the video streams are greatly decreased when applying PERT in heterogeneous environment. Furthermore, the Linux live streaming test indicates that PERT is able to reduce the playback glitches, when high resolution video is delivered over an end-to-end link with latency and packet loss.
