scope:

This Recommendation specifies the functional architecture of deep packet inspection (DPI) for future networks (e.g., software-defined networking, network function virtualization). The scope of this Recommendation includes:

• general DPI functional architecture aspects related to future networks;

• DPI functional architecture for software-defined networking;

• DPI functional architecture for network function virtualization;

• DPI functional architecture for service function chaining and DPI as a service;

• DPI functional architecture for network virtualization;

• DPI functional architecture for evolving mobile network.

Implementers and users of these described techniques shall comply with all applicable national and regional laws, regulations and policies. The mechanisms described in this Recommendation may not be applicable to the international correspondence in order to ensure the secrecy and sovereign national legal requirements placed upon telecommunications, but they shall comply with the ITU Constitution and Convention.
