5 Big data - Concept and application for telecommunications

3.1.1 Internet of things (IoT) [ITU-T Y.4000]: A global infrastructure for the information society, enabling
advanced services by interconnecting (physical and virtual) things based on existing and evolving
interoperable information and communication technologies.
NOTE 1 – Through the exploitation of identification, data capture, processing and communication
capabilities, the IoT makes full use of things to offer services to all kinds of applications, whilst ensuring that
security and privacy requirements are fulfilled.
NOTE 2 – From a broader perspective, the IoT can be perceived as a vision with technological and societal
implications.
3.1.2 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.

3.2 Terms defined in this Recommendation

This Recommendation defines the following terms:
3.2.1 IoT big data characteristics: IoT data set characteristics of high-volume, high-velocity and/or high-
variety related to the challenges of IoT data set operations.
NOTE 1 – The term ''volume'' refers to the size of the IoT data sets, the term ''velocity'' refers to the speed of
IoT data streams in and out of the IoT data sets and the term ''variety'' refers to the diversity of IoT data types
of the IoT data sets.
NOTE 2 – Additional dimensions of data, such as veracity, variability, etc., may also be associated with the
IoT big data characteristics.

NOTE 3 – Examples of operations on IoT data sets include collection, pre-processing, transfer, storage, query,
analysis and visualization.

4 Abbreviations and acronyms

This Recommendation uses the following abbreviations and acronyms:
API Application Programming Interface
EHM e-Health Monitoring

IoT Internet of Things
QoE Quality of Experience

QoS Quality of Service
SLA Service Level Agreement

5 Conventions

In this Recommendation:
The keywords "is required to" indicate a requirement which must be strictly followed and from which no
deviation is permitted if conformance to this Recommendation is to be claimed.
The keywords "is recommended" indicate a requirement which is recommended but which is not absolutely
required. Thus, this requirement need not be present to claim conformance.
