Network Fault Detection Using Test Packet Generation: A Survey

Abstract

Networks are becoming larger and a lot of advanced, yet directors think about various tools like ping and traceroute to correct issues. Instead of using different tools to debug the network problems, we introduced an automatic and systematic scheme for testing and debugging networks known as Automatic test Packet Generation (ATPG). This automated approach fetches router configurations to generate a device-independent model. The model is employed to get a minimum set of test packets to analyse each link in the network. The detected failures trigger a separate mechanism to localize the fault by sporadically sending test packets. ATPG will notice each operational (e.g., incorrect firewall rule) and performance problems. ATPG complements however goes on the far side earlier add static checking (which cannot observe functional or performance faults) or fault localization (which solely localizes faults given liveness results).
