Toward Optimal Network Fault Correction in Externally Managed Overlay Networks - 2010

ABSTRACT:

We have a tendency to think about an end-to-finish approach of inferring probabilistic data-forwarding failures in an externally managed overlay network, where overlay nodes are independently operated by varied administrative domains. Our optimization goal is to attenuate the expected cost of correcting (i.e., diagnosing and repairing) all faulty overlay nodes that can't properly deliver knowledge. Instead of initial checking the most likely faulty nodes as in standard fault localization issues, we prove that an optimal strategy ought to begin with checking one of the candidate nodes, which are identified based mostly on a potential operate that we have a tendency to develop. We propose many economical heuristics for inferring the best node to be checked in massive-scale networks. By in depth simulation, we show that we tend to will infer the simplest node in at least ninety fivep.c of time, and that initial checking the candidate nodes rather than the most seemingly faulty nodes will decrease the checking value of correcting all faulty nodes.
