Abstract

This letter considers problems of unfairness and excessive variations of the router queue associated with FAST TCP operations due to inaccurate estimation of the round-trip propagation delay. Using a simple example, we explain unfairness in FAST TCP caused by this inaccurate estimation. We also present analytical and simulation performance studies and show that improving this estimation by giving the first packet in every flow priority can improve fairness and reduce queuing variations. © 2005 IEEE.
