All the best Pascal From: RAW <raw-bounces@ietf.org<mailto:raw-bounces@ietf.org>> On Behalf Of Janos Farkas Sent: mardi 29 novembre 2022 9:25 To: raw@ietf.org<mailto:raw@ietf.org> Subject: [Raw] updating the RAW technologies draft Hi, As we discussed at IETF 115, the LS https://datatracker.ietf.org/liaison/1800/ explains that 3GPP SA2 has concluded their DetNet Study Item. I think it would be good to bring the RAW technologies draft up-to-date on that. This could be done by replacing [SP211633] 3GPP, "New SID: Extensions to the TSC Framework to support DetNet", 3GPP SP-211633, December 2021, <https://www.3gpp.org/ftp/tsg_sa/TSG_SA/ TSGS_94E_Electronic_2021_12/Docs/SP-211633.zip>. with [TR2370046] 3GPP, "Study on 5GS DetNet interworking", 3GPP TR23.700-46, August 2022, < https://portal.3gpp.org/desktopmodules/Specifications/SpecificationDetails.aspx?specificationId=3994<https://protect2.fireeye.com/v1/url?k=31323334-501d5122-313273af-454445555731-f4c9abe3e5fec6c8&q=1&e=7fe4d69f-f73a-4922-a4c8-68e02602cca0&u=https%3A%2F%2Fportal.3gpp.org%2Fdesktopmodules%2FSpecifications%2FSpecificationDetails.aspx%3FspecificationId%3D3994>>. and updating the corresponding text in 6.4.5, e.g.: OLD: IETF Deterministic Networking (DetNet) is the technology to support time-sensitive communications at the IP layer. 3GPP Release 18 includes a study [SP211633] on whether and how to enable 3GPP support for DetNet such that a mapping is provided between DetNet and 5G. The support for DetNet is considered to be added via the TSC framework introduced for Release 17. The study includes what information needs to be exposed by the 5G System and the translation of DetNet flow specification to 5G QoS parameters. Note that TSN is the primary subnetwork technology for DetNet. Thus, the DetNet over TSN work, e.g., [RFC9023], can be leveraged via the TSN support built in 5G. As the standards are ready for such an approach, it is out of scope for the 3GPP Release 18 study item [SP211633]. NEW: IETF Deterministic Networking (DetNet) is the technology to support time-sensitive communications at the IP layer. 3GPP Release 18 includes a study [TR2370046] on interworking between 5G and DetNet. Along the TSC framework introduced for Release 17, the 5GS acts as a DetNet node for the support of DetNet, see Figure 7.1-1 in [TR2370046]. The study provides details on how the 5GS is exposed by the TSCTSF to the DetNet controller as a router on a per UPF granularity (similarly to the per UPF Virtual TSN Bridge granularity shown in Figure 11). In particular, it is listed what parameters are provided by the TSCTSF to the DetNet controller. The study also includes how the TSCTSF maps DetNet flow parameters to 5G QoS parameters. Note that TSN is the primary subnetwork technology for DetNet. Thus, the DetNet over TSN work, e.g., [RFC9023], can be leveraged via the TSN support built in 5G. As the standards are ready for such an approach, it is out of scope for the 3GPP Release 18 study item [TR2370046]. Regards, Janos
