Description

When using NS3 with the same workload and network topology, sometimes I get identical results, but other times the results differ. Does this variation depend on factors such as the number of threads allocated, random number generation and different physical machine? Or should the NS3 simulation result always be deterministic?

Research direction

Start by reproducing the same workload and network topology, then compare results while varying the number of threads, random-number generation, and physical machine. Done means the issue documents whether NS3 results are deterministic and identifies the conditions that cause variation.
