Deep packet inspection (DPI) (or sometimes complete packet inspection) is a form of computer network packet filtering that examines the data and/or header part of a packet as it passes an inspection point, searching for non-protocol compliance, viruses, spam, intrusions or predefined criteria to decide if the packet can pass or if it needs to be routed to a different destination, or for the purpose of collecting statistical information. ……
Deep packet inspection (and filtering) enables advanced security functions as well as internet data mining, eavesdropping, and censorship.
