Body
Abstract: This Liaison Statement contains reply to IETF DetNet WG liaison
statement LS/i/r on request for feedback on work items related to deterministic
networking in SG13 (reply to SG13-LS208).

ITU-T SG13 appreciates the response from IETF DetNet WG, especially the
documents referenced in your reply (Liaison Statement). We believe these
documents are critical to our efforts and will significantly help us advance
our work in SG13 Q6 efficiently while minimizing duplication and overlap. SG13
Q6 looks forward to maintaining close collaboration with you on our shared
interest in QoS for deterministic networks.

ITU-T SG13 Q6 would welcome closer cooperation with IETF and IEEE on the topics
of deterministic networking and time-sensitive networking, to share ideas,
clarify scopes of work, and avoid overlap and duplication of work between our
organisations. If there are existing cooperative frameworks between IEEE and
IETF on this topic, the opportunity to be involved in these would be
appreciated.

With regard to the specific draft recommendation Y.qos-det-intwk-wan, please
find attached a gap analysis prepared by the contributors of this work item, as
well as the current draft Recommendation. Your views on this gap analysis would
be greatly appreciated.
