摘要
Aiming at the problem that the FAST TCP static mapping protocol parameter method can not achieve low queuing delay and rapid convergence at the same time, the paper studies the relation between the convergent velocity and FAST TCP parameters by theoretical analysis and NS-2 simulation, and on the basis of this, takes the number of packets each connection maintained in the link buffers as the dimension of the FAST TCP connection's slow start threshold, and proposes an enhanced method that computes the slow start threshold according to each FAST TCP flow protocol parameter, cooperatively estimates the network running state and dynamically tunes the controller gain parameter based on the TCP source local information. The NS-2 simulation results demonstrate that with the application of this enhanced method, the stability and the low queuing delay can be achieved simultaneously, while the system can also converge to equilibrium rapidly.
