Dear CATS WG, INT-AREA WG, APN mailing list members, Please find below some explanations by Daniel Huang about the relationships between SAN and CATS/APN. Daniel gave me his permission for this forwarding.

D.H>>Use cases upon which SAN is based include that raised and discussed in CATS about routing-based traffic steering in terms of computing resources of multiple cloud sites as well as servcie instances. On top of that, SAN also address the use cases of networking policies tailored for the service requirements. - how the SAN use of SIL in the network differs from the header discussed in the APN mailing list ? D.H>>SIL as well as the header in SAN is designed to indicate to both the network and computing site as an interface of SIL-associated service requirements as well as the service resource status. Termial, SAN ingress and egress, and even the cloud site where the service resides might be aware of SIL, so SIL in SAN is an identification of service sharing globally and uniquely semantics rather than within network between ingress and egress. furthermore ,SID in SAN header is a light-weight index of the identified service without any other information such as user, as well as service parameters. - where is the SIL added/removed to packets D.H>>SIL is in user data packets, SAN ingress and egress would route and forward the SIL-marked traffic according but would not have to either add or remove it at any occasion. Looking forward to listening to the SAN presentation, Regards, -éric [1] https://datatracker.ietf.org/wg/cats/about/ From: Int-area <int-area-boun...@ietf.org> on behalf of Wassim Haddad <wassim.haddad=40ericsson....@dmarc.ietf.org> Date: Sunday, 26 March 2023 at 13:07 To: Internet Area <int-area@ietf.org> Cc: "intarea-cha...@ietf.org" <intarea-cha...@ietf.org> Subject: [Int-area] Intarea WG agenda Hi, The Intarea WG meeting agenda is available at: https://datatracker.ietf.org/meeting/116/materials/agenda-116-intarea-01 Presenters, please upload your slides or send a copy to the chairs.
