Effects of Network Capacity under Variations of Network Structure and Routing Strategy

Network capacity, characterized by the maximum end-to-end traffic flow the network is able to handle without overloading, is an important index for network performance of real communication systems. In this paper, we estimate the effects of variations of network structure and routing strategy on network capacity. Simulation results reveal that the capacity depends on the underlying network structure and the capacity increases as the network becomes more homogeneous. It is also observed that the network capacity is greatly enhanced when the new traffic awareness routing strategy is adopted in each network structure
