Analysis of discrete event generation model on result of network simulation

In the event-driven network simulation, the generation distribution of discrete event is the basis of simulation running. Taking the currently common used OPNET network simulation tool as research object, the paper researched discrete event generation mechanism of OPNET through the simulation analysis on event generation rule of standard normal distribution and standard uniform distribution. The comparison of discrete event driven simulation experiments under two different distributions, the affect of discrete event with different probability density on the simulation result was analyzed.
