Summary

With the continuous cloudification of enterprise ICT and the continuous deployment of advanced industrial sensors, virtual reality (VR) and artificial intelligence (AI) applications, more and more data need to be transmitted from enterprise branches and individual users to the cloud for processing, and the calculation results need to be quickly provided for feedback and collaboration. All these applications require large data transmission across the end-to-end networks. The end-to-end networks are required to provide new functions to support the applications demanding large data transmissions.

This Recommendation gives an overview of applications demanding large data transmission, analyses common application characteristics and identifies related requirements for IMT-2020 networks and beyond. According to the requirements, enhanced network functions and new network functions to support applications demanding large data transmission are specified with respect to IMT-2020 networks and beyond functions identified in ITU-T Y.3102 [ITU-T Y.3102].

NOTE 1 - The Recommendation focuses on the specification of requirements and network functions in an end-to-end network perspective, and doesn’t intend to address specifically how these network functions can be implemented, including via current and/or future technologies or protocols. The implementation of these network functions is expected to be developed by other appropriate SDOs.

NOTE 2 - The applications that generate large data and the network infrastructure where these applications are carried over are responsible for ensuring appropriate data privacy. Data privacy aspects are out of scope of the Recommendation.
