Review on Automatic Test Packet Generation

Abstract

Now a day’s networks are increasing in size and it is becoming a difficult job for network administrators to debug the network, since they rely on traditional tools such as ping and trace route for this job. This paper puts an automated and systematic approach to test and debug a network which is called as Automatic Test Packet Generation (ATPG). ATPG produces a model which is independent on devices after reading configuration from routers. The model is used to generate a minimum set of test packets to exercise every link in the network or exercise every rule in the network. ATPG is capable of analysing both functional and performance problems. The working of few offline tools which automatically generate test packets are also given, but ATPG goes beyond the earlier work in static checking. Index Terms: performance analysis, test packet generation.
