ITU-T Recommendations

With the continuous cloudification of enterprise information and communication technology (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 provided quickly for feedback and collaboration. All these applications require large data transmission across end-to-end networks. End-to-end networks are required to provide new functions to support applications that demand large data transmissions.
This Recommendation gives an overview of applications demanding large data transmission, analyses common application characteristics and identifies related requirements for International Mobile Telecommunications-2020 (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 Recommendation ITU-T Y.3102.
NOTE 1 – The Recommendation focuses on the specification of requirements and network functions from an end-to-end network perspective, and does not 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 standards development organizations (SDOs).
NOTE 2 – The applications that generate large data and the network infrastructure over which these applications are carried are responsible for ensuring appropriate data privacy. Data privacy aspects are outside the scope of the Recommendation.
