To mitigate TCP global synchronization and improve network throughput, an improved TCP congestion control mechanism is proposed, namely P-TCP, which adopts the probability-based way to adjust congestion window independently when the network occurs congestion. Therefore, some P-TCP connections may decrease the congestion window greatly while other P-TCP connections may decrease the congestion window lightly. Simulation results show that TCP global synchronization can be effectively mitigated, which leads to efficient utilization of network resources as well as the effective mitigation for network congestion. Simulation results also give some valuable references for determining the related parameters in P-TCP.
