Abstract:   Classification of traffic is only the first step that helps identify different applications and Various actions, such as monitoring, rechecking, discovery, control, and optimization can then be performed on the identified traffic with the goal of improving the network performance. Deep Packet Inspection is a form of computer network packet filtering that examines the data spam, intrusions, or defined criteria to decide whether the packet may pass or if it needs to be redirected to a different destination, or, for the purpose of collecting statistical information. There are multiple ways to obtain packets for deep packet inspection. Using port mirroring(sometimes called Span Port) is a very common way and then an optical splitter.Deep Packet Inspection (and filtering) enables advanced network management, user service, and security functions as well as internet data mining, eavesdropping, and internet censorship.
