Application of adaptive probing for fault diagnosis in computer networks

Abstract

This dissertation presents an adaptive probing based tool for fault diagnosis in computer networks by addressing the problems of probe station selection and probe selection. We first present algorithms to place probe stations to monitor the network in the presence of various failures in the network. We then present algorithms for probe selection in an adaptive manner to perform fault diagnosis. We present algorithms considering both deterministic as well as non-deterministic environments. We present evaluation of the proposed algorithms through comprehensive simulation studies. The dissertation is available at http://www.cis.udel.edu/~natu/papers/dissertation.pdf.
