    Abstract

    The so-called power-law random graph (PLRG) has recently turned out to be an interesting model for very large, Internet-like networks. The resulting network possesses a kind of "soft hierarchy'', where large nodes play the role of a core network providing very good connectivity properties. In this paper, we study with simulations several aspects of the PLRG model. We check to what extent the shortest paths between randomly selected nodes really go through the core, propose a new way of adding link capacity diversity to the core by what we call natural routing, study the vulnerability of the network against node losses, and discuss the implications of the model to the efficiency of multicasting.
