Many networks such as the Internet have been found to possess scale-free and small-world network properties reflected …-organizing processes and more specifically, preferential attachment. New nodes in a network tend to attach themselves to other vertices …, the diameter of the network is small in comparison to other network structures, and movement through the network is …

We examine the interaction between two interconnected networks (e.g., two LECs) and a third network (e.g., an IXC … transit calls to the other LEC via the first LEC's network. We show that there is a wide set of cases in which competitive … transit could justify partial or even complete deregulation of access to a network's customer base …

To share the fixed cost of a communication network, the private cost method allocates to each subscriber the cost of …
