Research on Scale-free Network Congestion Control
Current research shows that many practical networks,such as communication networks,the Internet routing layer,and so the AS layer,as well as urban transportation network,aviation network has a scale-free features. Therefore,the scale-free network congestion control is a problem of practical significance,worthy of further study. We construct a typical scale-free network model to study the network congestion control method by simulating the behavior of traffic flowin the network,combined with the physical properties and routing strategy. The study shows that change of network topology has a large impact on network performance; dynamic routing strategy is better than static routing strategy to avoid network congestion; during bandwidth allocation,node capacity and node processing speed configuration,we must consider the node degrees in order to improve network performance and avoid network congestion. The research results of this paper provide a basis for the physical network configuration and routing mechanism design.
