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.


Victor O.K. Li ( was born in Hong Kong in 1954. He received SB, SM, EE and ScD degrees in Electrical Engineering and Computer Science from the Massachusetts Institute of Technology, Cambridge, Massachusetts, in 1977, 1979, 1980, and 1981, respectively. He joined the University of Southern California (USC), Los Angeles, California, USA in February 1981, and became Professor of Electrical Engineering and Director of the USC Communication Sciences Institute. Since September 1997 he has been with the University of Hong Kong, Hong Kong, where he is Chair Professor of Information Engineering. He also served as Managing Director of Versitech Ltd. (, the technology transfer and commercial arm of the University, from September 1997 to June 2004. Prof. Li serves on various corporate boards.
His research is in information technology, including all- optical networks, wireless networks, and Internet technologies and applications. Sought by government, industry, and academic organizations, he has lectured and consulted extensively around the world.
Prof. Li is very active in the research community, and has chaired various international conferences and served on the editorial boards of various international journals.
He has given distinguished lectures at universities around the world, and keynote speeches at many international conferences. Prof. Li has received numerous awards, including, most recently, the UK Royal Academy of Engineering Senior Visiting Fellowship in Communications, the KC Wong Education Foundation Lectureship, the Croucher Foundation Senior Research Fellowship, and the Bronze Bauhinia Star, Government of the Hong Kong Special Administrative Region, China.
