Question 3/13 - Functional architecture for NGN evolution (NGN-e) including support of IoT and use of software-defined networking
(Continuation of Question 5/13)
Motivation
As NGN establishes its position as an underlying mechanism for various applications, attentions are being paid to how advanced ICT systems are designed based on NGN and related architectures. Given rich features of NGN, highly capable ICT systems meeting industry demands can be realized by supplementary development based on NGN architecture. This is a promising way in terms of efficiency and time to market.
To support this approach, the NGN architecture defined in Recommendation ITU-T Y.2012 needs to be maintained and updated taking into account the latest industry situations. In addition, this work will stimulate the evolution of NGN architecture, especially, the support of intelligence capability enhancement (NICE) and use of SDN (software-defined networking) technologies.
Similarly to NGN, the maintenance and evolution of IPTV architecture defined in Recommendation ITU-T Y.1910 will be an important consideration.
Question
What new and revised framework and/or architecture Recommendations are required to realize convergence based on the NGN, IPTV and their evolutions?
Tasks
Study on general reference models of the NGN evolution for support of IPTV and emerging industry needs.
Preparation of frameworks to identify the basic architectural compositions of the NGN evolutions such as NICE for support of IPTV. These will be based on the identification of architectural requirements derived from the industry needs.
Study on general reference models of the NGN evolution for support of IoT
Identification of entities, their functions, and reference points, required to provide telecommunications services to support IoT. This includes the need for functional reference models, taking into consideration key themes to support ubiquitous environments, and the addition of new functions and/or modification of existing functions. This analysis should include consider the impact on existing Recommendations and interworking cases.
Study on using of SDN tehnologies on the architecture of NGN and its evolution.
Implementation framework related to provision of emergency telecommunications in NGN Identify the technical issues, measures, and functions of particular networking technologies that may be involved in meeting the requirements and capabilities of Recommendation ITU-T Y.1271, and develop any new Recommendations or enhance existing Recommendations (e.g., Y.2205) deemed to be required.
