| Abstract: | In this paper, the performance analysis of communication networks with i i d. service time and two independent arrival streams of "observed" and "unobserved" packets is studied. The arrivals of unobserved packets are Poisson with a known rate. Based on the idea of critical path, communication network's cabality is analysised using the perturbation analysis method and the calculate method used to analysising the perturbation is also proposed in this paper. Furthermore, performance measure, end to end delay D and probability of cell loss P loss are estimated, the trade off between D and P loss is acquired.$$$$ |
