| Abstract: | This paper studies the diffusion approximation for a class of the re-entrant networks under a general priority service discipline. Using the method of stochastic analysis, we demonstrate C-tightness of the scaled queue length processes and derive a sufficient condition for the existence of the diffusion approximation under a general priority service discipline. |
