Abstract:

Although the powerlaw distributions of nodes degree in scalefree networks are similar, the topologies of them are distinct in all probability. Considering the hierarchy and the quadrant feature, the distribution with weight between nodes and the statistical eigenvalues of complex networks, three restrictions, which are classification of nodes， distribution of dynamic increase and rules of attachment, are added, and a routerlevel topology model and algorithm are proposed. According to the quantitative data of simulation and theoretical analysis, the model is proved valuable and applicable.
