Question 4

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.
