Study on TCP-Friendly Protocol in Self-Similar Traffic Network
Yu Liu, Sun Yat · Chinese Journal of Computers · 2004
Since the traffic in modern telecommunication networks always shows self similarity or long range dependence, a new unicast TCP Friendly protocol using in self similar traffic network, called RAAR MT, is proposed in this paper. RAAR MT on line predicts the tendency of traffic level in the near future and use this predicted information to exert multiple time scale traffic control at receivers. Simulation shows that, comparing with RAAR protocol, RAAR MT protocol can enhance the tracking ability to the network state and gain 10%～20% performance improvement in loss rate on self similar traffic network. Even in traditional short range dependent environment, the performance of this protocol will not degrade severely. Comparisons have been made between RAAR MT and TFRC too. Results are that RAAR MT has better performance in TCP Friendliness, intra protocol fairness and smoothness in typical self similar network environment. RAAR MT is also a promising avenue of development for congestion control of multicast multimedia traffic, since it is not a per packet feedback and is mainly implemented at receivers.
