Deep Packet Inspection (DPI)
Deep packet inspection (DPI) is a form of filtering used to inspect data packets sent from one computer to another over a network. DPI is a sophisticated method of packet filtering that operates at the seventh layer (the application layer) of the Open System Interconnection (OSI) reference model. The effective use of DPI enables its users to track down, identify, categorize, reroute or stop packets with undesirable code or data.

Deep packet inspection (DPI) is a form of filtering used to inspect data packets sent from one computer to another over a network. DPI is a sophisticated method of packet filtering that operates at the seventh layer (the application layer) of the Open System Interconnection (OSI) reference model. The effective use of DPI enables its users to track down, identify, categorize, reroute or stop packets with undesirable code or data.
DPI is normally more effective than typical packet filtering, which inspects only the packet headers. DPI inspects the packet's data part (and sometimes the packet header) when it goes over an inspection point, attempting to find protocol noncompliance, intrusions, spam, viruses or other predefined factors to determine whether the packet can pass or whether it must be directed to another location.
With DPI, organizations can boost their network management systems without investing heavily in core network technologies.
Deep packet inspection is also known as complete packet inspection and information extraction.
