5.7.3. Network Simulation
Existing simulations could be simulated through the UI or batch command. In order to run multiple simulations on one PC at the same time, the Simulation Manager was utilized, and It is improved to enable more efficient execution than using the batch command. However, this also had a limitation of being executed on one machine. To overcome this limitation, a function called network simulation that enables distributed simulation of the network was implemented. The network simulation runs the simulation on multiple PCs and helps to obtain more efficient and faster simulation results.
The elements composing Network Simulation are as follows:
