Improved FAST TCP Preferences Selection Scheme
Zhi Liu · Jisuanji gongcheng · 2011
Aiming at the parameter selection problem of FAST TCP preferences selection scheme,the FAST TCP network congestion control model which includes the window update period parameter and the exponent filter element is established,and the stability of this model is analyzed with Routh-Hurwitz stability criterion.An improved preferences selection scheme is proposed to ensure the FAST TCP network stability according to the controller gain parameter,the window update period,and the network relevant parameters.The theoretical computation and the simulation results demonstrate that this improved scheme possesses more accurate select ranges in contrast to other related scheme.
