报告题目: From Isolated Queues to Interacting Queues—Is Burke’s Theorem Correct?
报告摘要:
Burke’s theorem is incorrect. We pinpoint the mistake in Burke’s theorem, and discuss its implication to networks of queues. We show that networks of queues are unstable, which implies that the physical systems modeled by such networks are unstable. The instability shows that the widely adopted stability assumption for performance evaluation of telecommunication and computer systems is false. To avoid distraction caused by unnecessary details, we base our discussion on the fact observed in a simple experiment, without involving specific models of concrete applications.
