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.

p:abstract
  • 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. This is in contrast to shallow packet inspection (usually called just packet inspection) which just checks the header portion of a packet. Deep packet inspection (and filtering) enables advanced security functions as well as internet data mining, eavesdropping, and censorship. Advocates of net neutrality fear that DPI technology will be used to reduce the openness of the Internet. DPI is currently being used by the enterprise, service providers and governments in a wide range of applications. (en)
