Performance analysis for partially observed communication networks

In this paper, we consider performance analysis for a FIFO queue with i.i.d. service time and two independent arrival streams of "observed" and "unobserved" packets. The arrivals of unobserved packets are Poisson with a known rate. Introducing the idea of critical path, the modeling and perturbation analysis method is proposed for the queue. 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.
