A topology partition algorithm for parallel network simulation based on load estimation and subdomain subtraction

Considering the low performance of the traditional topology partition-based parallel network simulation, the main method for Internet research at present, the paper puts forward a topology partition policy for parallel network simulation based on load estimation and subdomain subtraction. The results of the simulation based on the real topology obtained by Venusense prove that this partition policy can be used for real topology and large scale security event simulation. The test results prove that this partition policy can reduce the scale of router table by 19.8 percent, the simulation time by 17.2 percent, and the performance of simulation can be improved.
