ITU-T Y.4114 (07/2017) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and commun
14、ication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The
15、 World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1
16、. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a r
17、ecognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. T
18、he words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility
19、 that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recomme
20、ndation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation.

This Recommendation complements the developments on common requirements of the IoT ITU-T Y.4100 and f
28、unctional framework of the Internet of things (IoT) ITU-T Y.2068 in terms of the specific requirements and capabilities that the IoT is expected to support in order to address the challenges related to big data. In order to enhance the IoT system for dealing with the big data challenges in the IoT e
29、nvironment, the big data characteristics of IoT data and the IoT ecosystem from the IoT data point of view are investigated. From the perspective of the IoT data roles, big data challenges in the IoT are described. The requirements of the IoT for big data are specified addressing different IoT data
30、operations in the IoT which are impacted by big data. IoT data operations include data collection, data pre-processing, data analysis, data transfer, data storage, data query and data visualization. Building on the identified specific requirements of the IoT for big data, the capabilities of the IoT
31、 for big data are then specified. The scope of this Recommendation includes: Overview of big data in the IoT Requirements of the IoT for big data Capabilities of the IoT for big data An IoT use case with big data characteristics is provided in Appendix I. Details on relationships among IoT data role

ITU-T Y.4114 (07/2017) 3 Definitions 3.1 Terms defined elsewhere This Recommendation uses the following terms defined elsewhere: 3.1.1 Internet of things (IoT) ITU-T Y.4000: A global infr
37、astructure 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 c
38、apabilities, 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
39、-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
40、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
41、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
42、 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 Interfac

44、ance 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. Rec. ITU-T Y.4114 (07/2017) 3 6 Overview of big data in the IoT 6.1 Data char
45、acteristics in the IoT It is expected that in the future the quantity of connected things will be so huge that the IoT data will constitute a predominant part of the data carried by networks. These IoT data include not only data collected from things via devices and/or gateways within the IoT system
46、 and data processed within the IoT system itself, but also data injected from sources which are external to the IoT system (e.g., Web, social networks and industry domain specific information systems). In order to enhance the IoT system enabling it to deal with big data challenges in the IoT environ
47、ment, it is essential to investigate application independent characteristics (i.e., common characteristics) of IoT data. Consequently, according to the common characteristics of IoT data, the IoT system is enabled to handle the IoT data by the means of common capabilities facilitating data operation
48、s in the IoT. With respect to traditional data operations, operations on IoT data require additional study due to some unique characteristics of IoT data, named here as IoT big data characteristics, essentially due to the diversity of collected IoT data types and the broad variety of application sce
49、narios. The prominent IoT big data characteristics are IoT datas high volume (the size of the data sets), IoT datas high variety (heterogeneity of data types and sources) and IoT datas high velocity (the speed of data streams in and out of the data sets). These prominent IoT big data characteristics are the main driver of the requirements study in this Recommendation, helping to identify related common capabilities of the IoT system with respect to the variety of
