1 Motivation
A key characteristic of existing and emerging networks includes its softwarization/virtualization/intelligence/autonomics/trustworthiness for supporting applications and services with varied QoS/QoE requirements, all of which must be supported by these networks. Appropriate mechanisms are needed to achieve the required levels of QoS/QoE, especially for applications that are latency- and loss-sensitive. Some applications may also require a large amount of bandwidth and strict quality assurance, which makes the support for QoS/QoE challenging, in particular under a softwarized/virtualised/intelligence/autonomous/trustworthy network environment.
To enable QoS/QoE to support above networks characteristics, considerations need to be given to the following:
- end-to-end QoS/QoE assurance and application specific QoS requirements
- use of varied types of networking technology in the core network, in the access network, in endpoints and multiple administrative domains in an end-to-end path
- network resource optimization and orchestration for QoS/QoE enablement
- application and QoS/QoE mapping and its automation
- QoS assurance mechanisms for vertical sector applications
- QoS assurance mechanisms for QKDN and its extensions including quantum communications
- QoS assurance mechanisms for deterministic networking
- QoS assurance mechanisms using ai/machine learning mechanisms
- QoS support of AI for networking for IMT networks
- QoS support of non-terrestrial network (NTN) for IMT networks
- QoS support for providing energy savings
