Ning Wu successfuly defends Ph.D. dissertation

April 22, 2008

Ning Wu successfully defended his PhD on April 22, 2008. The abstract of his dissertation, Minimizing the Cost of Configuration Changes in Self-Managing Systems Via Closures, Matchings, and Marriages is as follows:

The transition planning problem for system configuration management is to determine, given a current system state and a set of new requirements, how to best satisfy those requirements. We begin by designing and implementing an "IP Address Closure" that manages IP address assignments for a network. This prototype proves that such a closure is feasible, but there is no good solution for handling infeasible transition requests. We can handle infeasible requests through virtualization, which allows transitions to be expressed as role mappings. Transitions between mappings can be computed via a series of polynomial reductions to a bipartite matching problem, whose solution is approximable in a distributed environment via the stable marriage algorithm.

Congratulations Ning!
