Study on the Fairness of TCP Connections Competing for Resources

The rapid growth of the Internet makes the research on resource allocation in computer networks a hot area in data communication research field.In the evolvement of the single quality of service to multiple levels of quality of service in Internet,the transmission control protocolb (TCP) will always be the main end to end resource allocation scheme.This paper studied the fairness of TCP connections with different propagation delays when competing for resources.It is showed that it is unfair for the connections with large propagation delays in TCP algorithm.When the propagation delays of the connections competing for bandwidth proportionally decrease,the unfairness becomes weaker.This conclusion will be very useful in the renovation of TCP algorithm.Meanwhile,the unfairness property has a promising interest to the design of differentiated services scheme.
