Protocols for control, management and orchestration of network resources
(Continuation of Questions 4/11 and 6/11)Motivation
During the 2013-2016 study period, ITU‑T SG11 has developed a series of resource control protocols for enhancing NGN capabilities. It is expected that the study of signalling requirements and protocols for control, management and orchestration of network resources continues and expands to new ITU-T study area such as ubiquitous sensor networks (USN), cloud computing networking, smart grid, Software-Defined Networking (SDN), Network Function Virtualization (NFV), International Mobile Telecommunication system 2020 (IMT-2020), future networks (FN), network virtualization, IPv6 transition, etc.
The behaviour of the traffic which is generated by new services, such as the service enabled by SDN, NFV, USN, etc., is very different from the traffic generated by existing NGN services. Accordingly, the architecture to control such new traffic may become more complicated. Bearer signalling requirements are closely related to resource control mechanisms and protocols.
With the emergence of various open source communities the lifecycle of development and testing will be much shortened. Accordingly, it is needed to consider more tight collaboration with these open source communities in order to promote the protocols to be implemented more efficiently. Accordingly, information model and data model-based signalling requirements and protocols are needed to be developed for further implementation using open source.

Study items to be considered include, but are not limited to:
- What signalling requirements and protocols are required for control, management, and orchestration of network resources involving new types of transport protocols and transport networks (e.g. USN, cloud computing networking, smart grid, FN, SDN, NFV, network virtualization and 5G/IMT-2020)?
- What new Recommendations are required to support bearer and resource control for new application areas such as unicast/multicast flows for IPTV service, home networking, and mobility?
- What new Recommendations are required to support handover control for mobility?
- What new Recommendations are required to support security of bearer and resource control and signalling?
- What new functional architecture and protocol enhancements are required to support bearer and resource control for services and applications of public interest, such as emergency call handling and disaster relief?
- What new Recommendations are required to support signalling of quality of service (QoS) information, traffic management?
- What enhancements to existing recommendations are required to provide energy savings directly or indirectly and efficient resource utilization in information and communication technologies or in other industries?
- What enhancements to new recommendations are required to provide such energy savings and efficient resource utilization?
- What new services can be identified for which the introduction of IPv6 is a necessary precondition?
- What new protocol procedures are required to implement the services identified above?
