Abstract
It has recently been shown [3, 5] that in the heavy traf- fc limit, the stationary distributions of the scaled queue length process of Generalized Jackson Networks converges to the stationary distribution of its corresponding Re ected Brownian Motion limit. In this paper we show that such an interchange of limits" is valid for the workload process of Stochastic Fluid Networks with Levy inputs. Our technique is of independent interest because we do not require the use of any Lyapunov techniques, a method that was used in the previous two papers.
