ITU Standards on big data

Advances in information and communication
technology (ICT) are enabling masses of data to be
generated, transmitted and stored, and this
explosive growth is increasing in pace. It is quite
difficult to analyze the data efficiently within the
allowable elapsed time. The paradigm developed
to solve the above problem is called big data. In
addition, the importance of big data has been
steadily increasing due to the rapid spread of data-
driven computing such as artificial intelligence.
With these considerations, ITU has been
developing Recommendations for big data since
2013. ITU newly defined a composite term for big
data as a paradigm for enabling the collection,
storage, management, analysis and visualization,
potentially under real-time constraints, of
extensive datasets with heterogeneous
characteristics (e.g. high-volume, high-velocity,
high-variety, etc.), as well as for its ecosystem.
Figure 1 shows the standardization scope of big Dr Kangchan Lee
data in ITU including a big data ecosystem, Rapporteur of Question 17
lifecycle of big data and three major (Requirements, ecosystem, and general
standardization area: supporting big data lifecycle, capabilities for cloud computing and big data)
security and management, and big data driven in ITU-T Study Group 13
applications.

In this regard, ITU-T has developed fundamental
standards for big data as follows:
– Recommendation ITU-T Y.3600 “Big data –
Cloud computing based requirements and
capabilities” provides requirements,

capabilities and use cases of cloud
computing based big data as well as its
system context. The big data ecosystem
defined in this Recommendation is being
used as a basis for the development of other
big data related Recommendations.

– Recommendation ITU-T Y.3601 “Big data –
Functional requirements for data
exchange” specifies the framework and
requirements for data exchange in a big
data ecosystem. This Recommendation
identifies general concepts, patterns,
activities, and functional requirements
based on the big data ecosystem and
capabilities defined in [ITU-T Y.3600].
