Now-a-days, networks are getting larger and more complex, hence network admin depend on normal tools such as ping and to trace route debug the problems. The authors are proposing automatic and systematic approach for testing and debugging networks called "Automatic test packet generation and fault localization". ATPG (Automatic Test Packet Generation) read router configurations and generates a unique model. This model is generating a minimum set of test packets to exercise every link in network exercise every rule in the network. Test packets are sent periodically and detected failure trigger a separate mechanism to localize the fault.
