AUTOMATIC TEST PACKET GENERATION

Abstract

Today's Network are very big and large. So if any error occur between any running nodes then it is very hard and complex to get the faulty node. We use our intuition to find error node. In this ATPG on periodic basis we send packets to find any bug in network. If bug occur then we find the rules which are previously experienced but now they are not satisfying using fault localization we localize the fault. ATPG can detect both functional (faulty line) and performance (congested queue) problems. Generally 4100 packets cover all the rules in big network and 55 packets are needed to cover every link. 4100 packet send ten times in a second which consumes less than 1% of bandwidth
