LS on work items related to deterministic networking in SG13

Abstract: This is the communication about the on-going work items on
deterministic communication services and networking in SG13 of ITU-T.

ITU-T Study Group 13 would like to inform you that it has consented one draft
new Recommendation related to deterministic communication services and
networking for the scope of large scale networks including IMT-2020 and beyond.

The following information gives more details about this draft Recommendation
and the corresponding document is attached.

Draft Recommendation ITU-T Y.3129 (formerly Y.det-FQ-rf) “Requirements and
framework for stateless fair queuing in large scale networks including IMT-2020
and beyond”

ITU-T Y.3129 specifies the requirements and framework for deterministic
networking with a set of work conserving packet schedulers that guarantees
end-to-end (E2E) latency bounds to flows.

The following related draft Recommendations were updated at the meeting.
- ITU-T Y.det-qos-req-ml-jrs “QoS requirements for machine learning based joint
resource scheduling to support deterministic communication services across
heterogeneous networks including IMT-2020 and beyond” (SG13-TD728/WP1) - ITU-T
Y.det-qos-arch-lan "Functional architecture for QoS guarantee of deterministic
communication services in local area network for IMT-2020 and beyond”
(SG13-TD729/WP1)

This information is for your consideration and we look forward to collaborating
with you in this area.
