Habitual Test Packet Generation And Fault Localization
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2015, Vol 3, Issue 12
Abstract
Networks are getting larger and more complex, yet administrators rely on rudimentary tools such as and to debug problems. We propose an automated and systematic approach for testing and debugging networks called “Automatic Test Packet Generation†(ATPG). ATPG reads the router configurations and generates a device-independent model. The model is used to generate a minimum set of test packets to (minimally) exercise every link in the network or (maximally) exercise every rule in the network. Test packets are sent periodically, and detected failures trigger a separate mechanism to localize the fault. ATPG can detect both functional (e.g., incorrect firewall rule) and performance problems (e.g., congested queue). ATPG complements but goes beyond earlier work in static checking (which cannot detect liveness or performance faults) or fault localization (which only localize faults given liveness results).Test packets are sent periodically and detected failure trigger a separate mechanism to localize the fault. ATPG can detect both functional testing and performance testing problems. ATPG complements but goes beyond earlier work in static checking or fault localization.
