Abstract
Now a day’s Networks are getting larger and more complex, hence network admindepend on normal tools such as ping and to trace route debug the problems. We are proposing automatic and systematic approach for testing and debugging networks called “Automatic Test Packet Generation and Fault Localization”. ATPG read router configurations and generates a unique model. 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).
