Body
LS on ongoing work items on deterministic communication services and networking
in SG13 of ITU-T.

ITU-T Study Group 13 would like to inform you that Question 6 of ITU-T SG13
consented two new draft Recommendations related to deterministic communication
services and networking for the scope of local area networks and large-scale
networks of the IMT-2020 network and beyond. The two draft Recommendations are
as following. Their corresponding documents are attached. Draft Recommendation
ITU-T Y.3120 (formerly Y.IMT-2020-fa-lg-lsn) “Functional architecture for
latency guarantee in large scale networks including IMT-2020 and beyond” Draft
Recommendation ITU-T Y.3121 (formerly Y.det-qos-reqts-lan) “QoS requirements
and framework for supporting deterministic communication services in local area
network for IMT-2020” Y.3120 specifies the functional architecture and
operation procedures for latency guarantee in large scale networks, with
work-conserving schedulers and interleaved regulators for flow aggregates. It
is the sequel of ITU-T Y.3113, which defines the requirements and framework for
latency guarantee in large scale networks. Y.3121 identifies the scenarios, QoS
requirements, and framework of deterministic communication services in local
area networks supporting heterogeneous technologies.

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