Using port mirroring (sometimes called Span Port) is a very common way, as well as physically inserting a network tap which duplicates and sends the data stream to an analyzer tool for inspection. Deep Packet Inspection (and filtering) enables advanced network management, user service, and security functions as well as internet data mining ...
The OSI protocol stack is structured into seven conceptual layers. The layers form a hierarchy of functionality starting with the physical hardware components to the user interfaces at the software application level. Each layer receives information from the layer above, processes it and passes it down to the next layer.

Traditional inspection technologies are unable to keep up with the recent outbreaks of widespread attacks. [2] Unlike inspection methods such as deep packet inspection (DPI), where only the data part (and possibly also the header) of a packet are inspected, deep content inspection (DCI)-based systems are exhaustive, such that network traffic packets are reassembled into their constituting ...
Packet processing systems separate out specific traffic types through the use of Deep Packet Inspection (DPI) [33] technologies. DPI technologies utilize pattern matching algorithms to look inside the data payload to identify the contents of each and every packet flowing through a network device. Successful pattern matches are reported to the ...
Health Level Seven, abbreviated to HL7, is a range of global standards for the transfer of clinical and administrative health data between applications with the aim to improve patient outcomes and health system performance. The HL7 standards focus on the application layer, which is "layer 7" in the Open Systems Interconnection model.
The transport layer and lower-level layers are unconcerned with the specifics of application layer protocols. Routers and switches do not typically examine the encapsulated traffic, rather they just provide a conduit for it. However, some firewall and bandwidth throttling applications use deep packet inspection to interpret
A middlebox is a computer networking device that transforms, inspects, filters, and manipulates traffic for purposes other than packet forwarding. [1] Examples of middleboxes include firewalls, network address translators (NATs), load balancers, and deep packet inspection (DPI) devices.
