A Comparative Estimation of Performance of Average Loss Interval Calculation Method in TCP-Friendly Congestion Control Protocol
Sang‐Chul Lee, Ju-Wook Jang · 2002
We propose a new estimation for rate adjustment in the face of a packet loss in the TFRC protocol, a TCP-Friendly congestion control protocol for UDP flows. Previous methods respond in a sensitive way to a single packet loss, resulting in oscillatory transmission behavior. This is an undesirable for multimedia services demanding constant bandwidth. The proposed TFRC provides more smooth and fair (against TCP flows) transmission through collective response based on multiple packets loss events. We show our Exponential smoothing method performs better than known Weight smoothing method in terms of smoothness and fairness.
