Big data - Concept and application for telecommunications 5

1 Scope

This Recommendation specifies a framework for big-data-driven networking. The scope of this
Recommendation includes the model architecture of big-data-driven networking (bDDN), the high-level
capabilities of bDDN and the interface capabilities among different planes and layers.

The following ITU-T Recommendations and other references contain provisions which, through reference in
this text, constitute provisions of this Recommendation. At the time of publication, the editions indicated
were valid. All Recommendations and other references are subject to revision; users of this Recommendation
are therefore encouraged to investigate the possibility of applying the most recent edition of the
Recommendations and other references listed below. A list of the currently valid ITU-T Recommendations is
regularly published. The reference to a document within this Recommendation does not give it, as a stand-
alone document, the status of a Recommendation.

3 Definitions

3.1 Terms defined elsewhere
This Recommendation uses the following terms defined elsewhere:
3.1.1 big data [ITU-T Y.3600]: A paradigm for enabling the collection, storage, management, analysis and
visualization, potentially under real-time constraints, of extensive datasets with heterogeneous
characteristics.
NOTE – Examples of datasets characteristics include high-volume, high-velocity, high-variety, etc.
3.1.2 deep packet inspection (DPI) [ITU-T Y.2770]: Analysis, according to the layered protocol
architecture OSI-BRM [ITU-T X.200], of:
• payload and/or packet properties (see list of potential properties in clause 3.2.11 of [ITU-T Y.2770]);
• deeper than protocol layer 2, 3 or 4 (L2/L3/L4) header information, and other packet properties

in order to identify the application unambiguously.
NOTE – The output of the DPI function, along with some extra information such as the flow information, is
typically used in subsequent functions such as reporting or actions on the packet.

3.2 Terms defined in this Recommendation
This Recommendation defines the following terms:

3.2.1 application-driven networking (ADN): ADN is a type of future network framework that provides the
network programmability for the applications. ADN is application quality of experience (QOE)-centric while a
traditional network is network efficiency-centric.

3.2.2 big-data-driven networking (bDDN): Big-data-driven networking (bDDN) is a type of future network
framework that collects big data from networks and applications, and generates big data intelligence based
on the big data; it then provides big data intelligence to facilitate smarter and autonomous network
management, operation, control, optimization and security, etc.
