Abstract:
The widespread of Voice over IP systems necessitate finding suitable and modern traffic engineering models that can help design cost-efficient systems and study their performance under various conditions. In this paper, we provide a new VoIP simulation suite that consists of a parametric simulator based on Non-homogeneous Poisson Process call arrival model, and a non-parametric simulator based on real traffic data. Our simulators are validated against real call data obtained from multiple offices of a production VoIP carrier network. The simulation results show that our simulator can provide up to 28% better resource utilization than the legacy Erlang B model. Our simulator can also help carriers dynamically allocate network bandwidth to meet various traffic demands.
