Body 
This liaison statement informs ITU-T SG2, SG11, SG17 and IETF CATS about the
initiation of new work item ITU-T Y.CPN-CL-Arch “Requirements and architecture
of CPN control layer for network resource in NGNe” that was started at the SG13
meeting (Geneva, 23 October -3 November 2023).

ITU-T Study Group 13 would like to inform ITU-T SG2, SG11, SG 17 and IETF CATS
that a new work item ITU-T Y.CPN-CL-Arch “Requirements and architecture of CPN
control layer for network resource in NGNe” was started at the SG13 meeting
(Geneva, 23 October - 3 November 2023). This work item specifies the
requirements and architecture of control layer in CPN, which addresses
capabilities of resource information collection, resource allocation and
network connection scheduling in CPN. The scope of this draft Recommendation
includes:

– Overview of CPN control layer;
– Service requirements of CPN control layer;
– Capability requirements of CPN control layer;
– Architecture of CPN control layer;
– Security considerations.

The baseline text of ITU-T Y.CPN-CL-Arch is available in SG13-TD369/WP3.
