Hi Ran, Thanks for your comments. While I don’t quite get your point of objection. Perhaps you have some misunderstanding about the relationship of the drafts mentioned.
RFC 8402 introduced the topology and service semantics of SR SID, this document proposed to add resource semantics to SIDs. Then MT or Flex-Algo are control plane mechanism for the distribution of topology-specific SIDs. The relationship with these documents are described in this draft. My reading of draft-peng in LSR and TEAS is that they may provide an option of control plane extensions for the resource-aware SIDs defined in this document, which just proves that the enhancement in this document is in the right direction, and more work based on it could be done in relevant WGs. Thus my suggestion would be to have the SR enhancement adopted in SPRING first, then more discussion about its control plane could happen in other WGs as the next step. Hope this helps.

It is not a new idea for each Virtual Network to have its own SIDs. e.g. The earlist description of the SID be allocated per flex-algorithm and related metric information was in draft-hegdeppsenak-isis-sr-flex-algo-00(2017.7.17) (now is draft-ietf-isis-sr-flex-algo) . The earlist description of the SID be allocated per MT was in draft-filsfils-spring-segment-routing-04(2014.7.3) (now is RFC8402 ), and draft-peng-lsr-network-slicing-00(2019.2.25) describe the SID be allocated per AII(alias alice). For slice resources, https://tools.ietf.org/html/draft-peng-teas-network-slicing-03 induced slice-id(AII) for slice resources management, and can differentiate them (e.g. L2 link or L3 interface, section 7 ), and how to compute SR-BE or SR-TE path according to AII combined with other criteria.
