Large-Scale Network Automatic Partitioning and Simulation System based on PDNS

This paper presents a parallel network simulator based on PDNS, which can directly use complex network topologies as inputs. It can automatically partition the network topologies, compute remote routing states for each simulation process. Our simulator also improves routing lookup mechanisms of PDNS and gives the visualization results of the simulation. Experimental results show that our simulator can implement the simulation of network applications on large-scale complex network topologies, with the simulation efficiency as high as PDNS.
