DPI: Deep Packet Inspection Motivations

“DPI” is being implemented to provide a range of services from content filtering, to web application firewalls, application aware policy enforcement, and others. DPI applications solutions are a mix of both compute and packet processing, real-time and non-real time processing, as well as in-the-path/on-the-wire and off-the-wire/off-the-path processing depending on the DPI application. As advances in computing and packet processing occur, the ability to inspect and act on more traffic to enable a variety of useful services is enabled within the network.

DPI Applications Friend or Foe?

Deep Packet Inspection, or DPI, is a relatively new addition to the general telecom vocabulary. DPI is being promoted as a solution for many of the issues faced by fixed and mobile broadband operators. In fact, DPI as a concept has been around for a long time but it is only now coming to the forefront because the technology has reached a price and performance threshold where it is commercially viable for deployment – and because of certain controversial application areas where it might be used (more on that later).

CPE WAN Management Protocol and FAP Management

Standardization of Femtocell technology has come a very long way. This progress is largely due to the leadership of the telecom industry consortium known as the Femto Forum (www.smallcellforum.org/) working with various standardization organizations such as the 3rd Generation Partnership Project (3GPP, www.3gpp.org) and the Broadband Forum (BBF, www.broadband-forum.org).
