Adaptive Probing: A Monitoring-Based Probing Approach for Fault Localization in Networks
نویسندگان
چکیده
The past research in fault localization in distributed data centers has used either monitoring or probing techniques in isolation. In this paper, we argue that effective fault localization solutions can be built by exploiting the information captured by both the techniques. Based on this concept, we propose an adaptive probing solution for fault localization where information from monitoring agents is used to adapt probing policies such that probe traffic is reduced, localization accuracy is increased, and localization time is minimized. We demonstrate the proof-of-concept through experimental results. Keywords-Fault Localization, Probing, Monitoring.

Probabilistic Fault Diagnosis Using Adaptive Probing
Past research on probing-based network monitoring provides solutions based on preplanned probing which is computationally expensive, is less accurate, and involves a large management traffic. Unlike preplanned probing, adaptive probing proposes to select probes in an interactive manner sending more probes to diagnose the observed problem areas and less probes in the healthy areas, thereby signi...

Increase in the network usage for more and more performance critical applications has caused a demand for tools that can monitor network health with minimum management traffic. Adaptive probing has the potential to provide effective tools for end-to-end monitoring and fault diagnosis over a network. Adaptive probing based algorithms adapt the probe set to localize faults in the network by sendi...
متن کاملFault Localization in All-Optical Mesh Networks
Fault management is a challenging task in all-optical wavelength division multiplexing (WDM) networks. However, fast fault localization for shared risk link groups (SRLGs) with multiple links is essential for building a fully survival and functional transparent all-optical mesh network. Monitoring trail (m-trail) technology is an effective approach to achieve the goal, whereby a set of m-trails...
