1 Scope
The scope of this Supplement to [ITU-T Y.3033] includes the following items:

• informative illustrations and descriptions of service scenarios and use cases supported by data
aware networking;
• elaboration of the benefits of data aware networks to the scenarios and use cases, as well as several
migration paths from current networks to data aware networks.

3 Definitions

3.1 Terms defined elsewhere
This Supplement uses the following terms defined elsewhere:
3.1.1 data object [ITU-T Y.3033]: An individually identifiable unit of information created by individuals,
institutions and technology to benefit audiences in contexts that they value.

3.1.2 future network (FN) [ITU-T Y.3001]: A network able to provide services, capabilities, and facilities
difficult to provide using existing network technologies. A future network is either:
a) A new component network or an enhanced version of an existing one, or

b) A heterogeneous collection of new component networks or of new and existing component
networks that is operated as a single network.

3.1.3 identifier [b-ITU-T Y.2091]: An identifier is a series of digits, characters and symbols or any other form
of data used to identify subscriber(s), user(s), network element(s), function(s), network entity(ies) providing
services/applications, or other entities (e.g., physical or logical objects). Identifiers can be used for
registration or authorization. They can be either public to all networks, shared between a limited number of
networks or private to a specific network (private IDs are normally not disclosed to third parties).

3.1.4 name [b-ITU-T Y.2091]: A name is the identifier of an entity (e.g., subscriber, network element) that
may be resolved/translated into an address.

3.1.5 service [b-ITU-T Z. Sup.1]: A set of functions and facilities offered to a user by a provider.

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

3.2.1 named data object (NDO): A data object that is identifiable by a name.
NOTE – In this Supplement, NDOs include both what is not executable as a software program, and what is executable
as a software program.
3.2.2 NDO-data: An NDO that is not executable as a software program (e.g., videos, text files and
measurement data).
3.2.3 NDO-func: An NDO that is executable as a software program. NDO-func takes NDO-data as input
and produces another set of NDO-data as output after processing.
