Now a large number of intermediate nodes face a fact of using drop tail queue management, therefore a random back-off TCP congestion control algorithm named TCP Njust is proposed. When congestion occurs, randomly reduce the congestion window within a certain range, but when congestion avoid, congestion window is randomly increased within certain limits to reduce TCP global synchronization. This algorithm requires a random function on the base of Newreno. Simulation results show that this algorithm performs better than Newreno, and also better than Vegas when a large number of burst data stream occurs in the network, and it';s suitable for use in the internet.
