Mapping Strategy of Simulation Nodes Based on Topology Partitioning

In the visualized network simulation system, both hardware and software resources are partly occupied to run the simulation nodes. And distributed simulation service is required to be provided by multiple physical servers if the scale of simulation network is rather large. In order to solve the problem of mapping from simulation nodes to physical servers in the distributed environment, this paper presents a mapping strategy of simulation nodes based on topology partitioning. First, we transform the topology network into the weighted graph according to the degree of the nodes and links. Then we map the simulation nodes based on the weighted graphs. By using the proposed method, the loading balance among the multi-physical servers can be achieved well, and fewer physical servers’ resources are consumed.
