Self-Stabilization in Network Services

This talk begins with a mini-tutorial on system stabilization, whose main idea is that the system when placed in an arbitrary state eventually converges to desired states. This idea, which has been deeply studied in distributed computing over the past three decades, is finding renewed application in sensor networks and internet services. We will overview some such applications that we have encountered in our work with DARPA Network Embedded Systems platforms and with Microsoft Research. And, given the challenges of scale that these applications introduce, we will discuss techniques for scaling self-stabilization in the dimensions of resource, time, network size, and code size.

Anish Arora is Professor of Computer Science at The Ohio State University. His research interests focus on the problem of fault-tolerance and security in modern distributed and networked systems. Arora has a B.Tech. degree from IIT, Delhi and M.S. and Ph.D. degrees from The University of Texas at Austin, all in Computer Science. He was program chair of the 1999 Workshop on Self-Stabilization (now called the Symposium on Self-Stabilization) and co-chair of the Seminar on Self-Stabilization at Dagstuhl, Germany in 1998 and in 2000, at Luminy, France in 2002, and he is program chair for an upcoming Seminar on Self-Stabilization in Banff, Canada and an International Conference on Distributed Computing Systems.
