Fault-Tolerant Communication in Point-to-Point Networks

One of the challenges in fault-tolerant communication is to achieve
certain objectives without excessive cost in collecting and
maintaining fault information. We propose an approach that achieves
optimal routing with limited amount of global fault information. This
approach is illustrated by the concept of a safety level (vector) that
can be applied to hypercube- and mesh-connected systems. In this
approach each node is associated with a safety level, which is an
approximate measure of the number and distribution of faulty nodes in
the neighborhood.  The safety level can be used to determine routing
feasibility as well as to provide necessary information to facilitate
optimal routing. This talk addresses related issues and possible
future directions in this area.


Bio

Dr. Jie Wu received the B.S. degree in computer engineering in 1982
and the M.S. degree in computer science in 1985, from Shanghai
University of Science and Technology, and the Ph.D. degree in computer
engineering from Florida Atlantic University, Boca Raton, Florida, in
1989. Between 1985-1987, he taught at Shanghai University of Science
and Technology.  Since August 1989 he has been with the Department of
Computer Science and Engineering, Florida Atlantic University where he
is a Professor and the Director of CSE graduate programs. 

Dr. Wu has published over 100 papers in various journal and conference
proceedings such as IEEE Transactions on Software Engineering, IEEE
Transactions on Computers, IEEE Transactions on Parallel and
Distributed Systems, Journal of Parallel and Distributed Computing and
Concurrency: Practice and Experience. His research interests are in
the area of parallel/distributed systems, fault-tolerant computing,
interconnection networks, Petri net applications, and software
engineering.  

He serves on the editorial board of the International Journal on
Computers and Applications.  He served on the program committees for
the 1996 and 1998 IEEE International Conference on Distributed
Computing Systems and the 1999 International Conference on Parallel
Processing.  He is a program co-chair of the 12th ISCA International
Conference on Parallel and Distributed Computing Systems in 1999.  He
is also a co-guest-editor of a special issue in IEEE Transactions on
Parallel and Distributed Systems on ``Challenges in Designing
Fault-Tolerant Routing in Networks". He is the author of the text
_Distributed System Design_ published by the CRC press.  Dr. Wu a
recipient of the 1996-97 Researcher of the Year Award at Florida
Atlantic University. He is an IEEE Computer Society Distinguished
Visitor. Dr. Wu is a Member of ACM and ISCA and a Senoir Member of
IEEE.
