Draft new Recommendation ITU-T Y.det-qos-intwk-wan: “Requirements and framework of deterministic QoS interworking mechanism in heterogeneous wide area network including IMT-2020 and beyond”
Draft new Recommendation ITU-T Y.qos-sre-rf: “Requirements and framework for service rates estimation with packet metadata for stateless admission control”
Body 
ITU-T Study Group 13 Working Party 4 would like to inform you that Question
6/13 of SG13 consented one work item which is related to deterministic
networking

-       Recommendation ITU-T Y.3441 (ex Y.det-qos-req-ml-jrs) “QoS requirements
and framework for deterministic communication services enabled by machine
learning based joint resource scheduling” (SG13-TD379/WP4)

The following deterministic networking related draft Recommendations were
updated at the meeting.

-       Y.det-qos-intwk-wan: Requirements and framework of deterministic QoS
interworking mechanism in wide area network for IMT-2020 and beyond 
(SG13-TD411/WP4)

-       Y.qos-sre-rf: Requirements and framework for service rates estimation
with packet metadata for stateless admission control (SG13-TD412/WP4)

ITU-T SG13 Working Party 4/13 is looking forward to continuing collaboration
with IETF DetNet WG and IEEE 802.1 TSN TG in the context of deterministic
networking aspects.
