Protocols for control, management and orchestration of network resources
|
| Description:
|
1 Motivation
WTSA Resolution 77 (Rev. Hammamet, 2016) aims to enhance the standardization work in the ITU Telecommunication Standardization Sector for software-defined networking (SDN) and instructs ITU-T study groups to continue to expand and accelerate the work on SDN standardization, especially carrier SDN, to research the advancement of emerging technology such as NFV container/docker to evolve the SDN technology, and to continue to develop the ITU T SDN standards to enhance interoperability between the controller products.
This Question has developed a series of data models, signalling requirements and protocols related Recommendations on control, management and orchestration of bearer network resources. It is expected that the standardization on the above aspect continues based on network technologies including but not limited to SDN and other related network softwarization technologies such as Network Function Virtualization (NFV), distributed orchestration, service function chaining, network slicing and service aware network, computing power network, cloud computing networking, network virtualization, IPv6 transition, big data driven networking, lossless network, IMT-2020 networks and future networks (FN), and expands to other emerging IT supporting technologies used for bearer network, such as Artificial Intelligence/Machine Learning (AI/ML), Distributed Ledger Technology, distributed cloud, Multi-access Edge Computing (MEC), microservice architecture and confidential computing.
As one of the major network development trends, network automation promotes the network configuration and deployment agility, and leads the whole network more predictable and uniform. Network automation could be implemented based on the collection of some above-mentioned network and related IT supporting technologies, and the standardized modelling languages, tools, and processes.
The behaviour of the traffic which is generated by more and more new services, such as the service enabled by SDN and other related programmable network, computing power network, and other emerging IT supporting technologies used for bearer network, is very different from the traffic generated by the traditional NGN services. Accordingly, the architecture to control such new traffic may become more complicated and the corresponding bearer network signalling requirements are closely related to the new network resource control mechanisms and protocols.
