In today’s era, working on network is complex process as many users including naïve users, administrators etc. uses tools like ping and traceroute to debug problems. We have studieda systematic and automated approach for testing and debugging networks called An Automatic Test Packet Generation by using fault localization. ATPG interpret the router configurations and generates device-independent model. The model is used to generate a least possible set of test packets to exercise each link in the network or exercise each rule in the network. The Test packets are sent periodically and if detected failures trigger a distinct mechanism to localize faults. ATPG can detect mutually functional and performance problems. ATPG complements but it goes beyond previous work in static checking or fault localization. It is used for testing the liveness of the underlying topology and the congruence among data plane state and configuration specification. In this paper the small number of test packets suffices to test whole rules in these networks. ATPG code and datasets are available publicly.
