Abstract:
In order to study the phenomenon of lock-out and chaos in transmission control protocol ( TCP) congestion control, this paper presents a way of relieving the lock-out for TCP senders to avoid the unfairness of network transmission caused by lock-out. Analyzing the influence of their initial values on the state of logistic map, this paper proves that different initial values can change the state of chaotic systems. This evidence is used for analysing the TCP congestion control. Different initial values for network systems with determined parameters can cause periodic changes,chaos or instability, and lock-out is a kind of instability of network. Lock-out can be avoided by changing the initial values of the TCP senders. Simulations show that this method can effectively relieve lock-out,enable the network back to chaotic state,and improve the fairness of network transmission.
