Parameter condition for global asymptotic stability of FAST TCP in the presence of cross traffics

摘要

We consider the global asymptotic stability of FAST TCP in the presence of cross traffics as well as network feedback delays. Based on a continuous-time dynamic model that describes the FAST TCP source and the queuing delay dynamics with cross traffics, we achieve a sufficient condition for the global asymptotic stability. The sufficient condition is expressed in terms of the tuning parameter ;1; independently of the update gain ;3;. The simulation results demonstrate the validity of the sufficient condition for the global asymptotic stability of FAST TCP.
