Topology aggregation model based on focus folding for network simulation by Zhao-xin ZHANG, Yue-jin DU, Ke WANG, Zhen-quan DING, Zhi-yu HAO

“…High resource consumption is the main problem of large-scale network simulation,to solve this problem,the topology aggregation model based on focus folding for network simulation was put forward.According to the abstract coefficients,the terminal node abstract,tree shrinking,and cut-edge abstract algorithm was adopt to abstract the topology.The test results show that,this technology can reduce the router node about 30 percent,the link between routers about 13.74 percent,total node about 98.48 percent,and total link about 96.1 percent.Simulating DDoS on the topology with 2.5 million nodes only need 400s time and 2 710MB memory.Take Shandong topology as an example to simulate DDoS,after abstracted,simulation memory and time have been reduced about 75.34 percent and 91.76 percent respectively.Take Beijing topology as an example to simulate worm,after abstracted,simulation memory and time have been reduced about 68.84 percent and 38.64 percent respectively,which prove that this mode can improve the simulation scale and efficiency and decrease the resource consumption and running time of simulation.…”
