1 Scope

This Recommendation specifies the requirements of data aware networking (information centric networking)
derived from the use cases and scenarios described in ITU-T Supplement 35 to Recommendation Y.3033. It
identifies its capabilities to fulfil the requirements, and describes the components including the capabilities
of the corresponding components.

3 Definitions

3.1 Terms defined elsewhere
This Recommendation uses the following terms defined elsewhere:

3.1.1 access control [b-CCITT X.800]: The prevention of unauthorized use of a resource, including the
prevention of use of a resource in an unauthorized manner.
3.1.2 authorization [b-CCITT X.800]: The granting of rights, which includes the granting of access based
on access rights.
3.1.3 availability [b-CCITT X.800]: The property of being accessible and useable upon demand by an
authorized entity.
3.1.4 data ID [ITU-T Y.3033]: An identifier used to identify a data object. It has a form of a series of digits,
characters and symbols or any of these combinations, which generally do not have any meaning.
In this Recommendation, “data ID” and “ID” are used interchangeably.
3.1.5 data integrity [b-CCITT X.800]: The property that data has not been altered or destroyed in an
unauthorized manner.
3.1.6 data name [ITU-T Y.3033]: A string of alpha-numeric characters that is used to identify the data
object. A data name, which may have variable length, is usually configured in such a way that it would be
easier to be read and remembered by humans.

In this Recommendation, “data name”, “NDO name”, and simply “name” are used interchangeably.
