Networks beyond IMT2020: Quality of service (QoS) mechanisms
(Continuation of Question 6/13)
Motivation
A key characteristic of existing and emerging networks is the use of a smart transport including its softwarization/virtualization for supporting applications and services with varied QoS/QoE requirements, all of which must be supported by this smart transport. 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 network environment.
To support QoS/QoE in a consistent, efficient, dynamic and secure fashion, considerations need to be given to the following:
– End-to-End QoS/QoE assurance and application specific QoS requirements
– Use of varied types of transport 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
– Use of AI/machine learning mechanisms
– Application and QoS/QoE mapping and its automation
– QoS assurance mechanisms for vertical sector applications
The following major Recommendations, in force at the time of approval of this Question, fall under its responsibility:
– ITU-T Y.3106, Y.3107, Y.3170, Y.3175.
