deep packet inspection

   Also found in: Wikipedia 0.06 sec.

Analyzing network traffic to discover the type of application that sent the data. In order to prioritize traffic or filter out unwanted data, deep packet inspection can differentiate data, such as video, audio, chat, voice over IP (VoIP), e-mail and Web. Inspecting the packets all the way up to layer 7 (see OSI model), it can be used to analyze anything and everything within the packet that is not encrypted. For example, it can determine not only that the data is a Web page, but also which Web site it comes from. See packet filter.
