MP-Start:bandwidth measurement based and phase-divided TCP slow start mechanism
To set appropriate threshold value（ssthresh） of slow start and eliminate network oscillation caused by bursty traffic,a new measurement-based and phase-divided slow start mechanism was proposed,which was called MP-Start.MP-Start employs effective online bandwidth measurement technology to update the...

| description | To set appropriate threshold value（ssthresh） of slow start and eliminate network oscillation caused by bursty traffic,a new measurement-based and phase-divided slow start mechanism was proposed,which was called MP-Start.MP-Start employs effective online bandwidth measurement technology to update the ssthresh with appropriate value dy-namically,and adjusts the increment of congestion window（cwnd） in different phase of the startup.MP-Start increases cwnd with half of the difference between ssthesh and cwnd,iterates and gradually closes up ssthresh,of which the incre-ment is small at start phase and end phase and comparatively large at the middle phase of the startup of a connection,the largest increment is no more than one quarter of ssthresh.In order to improve the performance of this algorithm,a flexi-ble parameterized model and an adaptive parameter setting solution are designed.And series simulation experiments in-dicate that MP-Start significantly decreases dropped packets,data transforming time,packet queue length of shared link,and also improves network performance and smoothness of connections. |
