Core network aspects 1

3.1.8 media [b-ITU-T Y.2012]: One or more of audio, video, or data.

3.1.9 media stream [b-ITU-T Y.2012]: A media stream can consist of audio, video, or data, or a
combination of any of them. Media stream data conveys user or application data (i.e., a payload) but not
control data.

3.1.10 network intelligence capability enhancement (NICE) [ITU-T Y.2301]: An enhanced NGN supporting
some intelligent capabilities for the provisioning of services according to requirements of users and
application providers. These intelligent capabilities (termed as "NICE capabilities") enable operators to assign
and dynamically adjust specific network resources based on the requirements, as well as support interfaces
for users and applications enabling on demand resource and service provision.

3.1.11 next generation network (NGN) [b-ITU-T Y.2001]: A packet-based network able to provide
telecommunication services and able to make use of multiple broadband, QoS-enabled transport
technologies and in which service-related functions are independent from underlying transport-related
technologies. It enables unfettered access for users to networks and to competing service providers and/or
services of their choice. It supports generalized mobility which will allow consistent and ubiquitous provision
of services to users.

3.1.12 service [b-ITU-T Y.2091]: A set of functions and facilities offered to a user by a provider.
3.1.13 software-defined networking (SDN) [b-ITU-T Y.3300]: A set of techniques that enables to directly
program, orchestrate, control and manage network resources, which facilitates the design, delivery and
operation of network services in a dynamic and scalable manner.

3.1.14 user [b-ITU-T Y.2201]: A user includes end user [b-ITU-T Y.2091], person, subscriber, system,
equipment, terminal (e.g., FAX, PC), (functional) entity, process, application, provider, or corporate network.

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

3.2.1 S-NICE controller capabilities: Capabilities providing a means to control the S-NICE infrastructure
capabilities (such as data transport and processing on per flow basis) requested by applications.

3.2.2 S-NICE infrastructure capabilities: Capabilities which are controlled by the S-NICE controller
capabilities to perform actions according to applications' requirements.

3.2.3 S-NICE orchestration capabilities: Capabilities which coordinate with applications and S-NICE
controller capabilities to provide software-defined control and management of network resources and users,
as well as service creation and provisioning.

3.2.4 virtualized network: In this Recommendation, a network that makes use of virtualization
technologies. It enables the abstraction of network resources such as creation of logically isolated virtual
networks over a single physical network, and aggregation of multiple network resources as a single network
resource.

3.2.5 virtualized network function: In this Recommendation, a network function whose functional
software is decoupled from hardware, and runs on virtual machine(s).
