,Long Term Behavior of Dynamic Equilibria in?Fluid Queuing Networks,d. The proof is based on the analysis of a rather non-obvious potential function that turns out to be monotone along the evolution of the equilibrium. Furthermore, we show that the steady state is characterized as an optimal solution of a certain linear program. When this program has a unique soluti
