Architectures, management, protocols and Quality of Service
(Continuation of part of Q3/20)Motivation
As the Internet of Things (IoT) establishes its position as an underlying mechanism for various applications, special attention is being paid to how advanced information and communication technology (ICT) systems are designed based on IoT and related conceptual architectures including network requirements and protocol. Given the rich features of IoT, highly capable ICT systems meeting vertical industry demands can be realized by supplementary development based on IoT architectures. This is a promising way in terms of efficiency and time to market.
To support this approach, the IoT architectures, their functionalities, data models, management mechanisms, protocols, and Quality of Service (QoS) have to be studied, also building on existing Recommendations, including ITU-T Y.2060/ITU-T Y.4000.
This Question addresses IoT functional architectures, protocols, management mechanisms, and QoS (including performance) of IoT and Smart Sustainable Cities and Communities (SC&C), which needed to construct architectural frameworks for the following reasons:
- to control network attachment procedures (including mobility management);
- to control session establishment and release, to control network resources (including QoS control);
- to interact with services and applications and to interact with legacy networks, etc.
Study items to be considered include, but are not limited to:
- What new and revised architectural framework Recommendations are required to realize IoT and SC&C?
- What technologies including networks, interfaces, functions, management mechanisms, as well as protocols are required for the architecture of IoT and SC&C?
- What functionalities of the ICT technologies, signalling and control architectures are required to support services and/or applications of IoT and SC&C?
- What enhancements to existing connectivities, interfaces, functions, management mechanisms and protocols are required to support machine-to-machine (M2M) communication services and/or applications of IoT and SC&C?
- What performance requirements of connectivity technologies are required to support services and/or applications of IoT and SC&C?
- What are the mechanisms for achieving QoS and its measurement principles required for IoT and SC&C?
- Collaboration with which standards development organizations (SDOs) would be necessary to maximize synergies and harmonize existing standards?
Tasks include, but are not limited to:
- Developing Recommendations, Reports, Handbooks, Guidelines, etc. as appropriate on:
- Conducting studies on general reference models on IoT and vertical industry needs;
- Developing frameworks to identify the basic architectural compositions and views on IoT. These will be based on the identification of architectural requirements derived from the industry needs;
- Identifying entities, their functions, and reference points required to provide support to IoT applications and services;
- Determining the requirements that the connectivities and protocols are intended to support. It is anticipated that these requirements will need to be periodically refined to reflect the evolution of IoT related technologies taking into consideration the connectivities, management mechanisms and protocols available from ITU-T and other SDOs;
- Developing modifications and enhancements to the signalling requirements, connectivity technologies, management mechanisms and protocols that will enable them to meet the IoT requirements and architecture;
- Identifying performance requirements of connectivity technologies that will enable them to meet the IoT requirements;
- Identifying mechanisms for achieving QoS and its measurement principles required for IoT and SC&C;
- Identifying interfaces for which interoperability between different IoT network elements is desirable and for which detailed requirements need to be studied and control protocols need to be standardized;
- Defining interworking with legacy systems;
- Studying specific IoT signalling requirements and protocols such as peer-to-peer and mesh architectures;
- Developing intelligence control related technologies that will provide support to IoT applications and services for various verticals and systems;
- Identifying mechanisms for achieving architectural interoperability for IoT and SC&C;
- Providing the necessary collaboration for joint activities in this field within ITU and between ITU-T and SDOs, consortia and fora.
