| Abstract: | By using Markov Reward Model (MRM) and Continuous Time Markov Chain (CTMC) Stochastic Process Z(t) was described. The oriented system viewpoints and the oriented user viewpoint were unified by network accumulate performance parameter's double Laplace transform expression. The model can be used to calculate and forecast several network's performance parameters. In order to solve complex iterative time's calculation process, an approximation of iterative time's algorithm derived out. The numerical value of network accumulate performance was calculated and analyzed in a sample network topology structure. |
