A few comments - - Section 2 A classifier SHOULD assign an NSH Service Path Identifier (SPI) per SR policy so that different traffic flows that use the same NSH Service Function Path (SFP) but different SR policy can coexist on the same SFP without conflict during SFF processing. Why not MUST? Jim> yes and good catch thank you. I will update the text. - Section 4, I suggest adding some recommendations related to the cache? How long to keep (aging)? What happens in case of a cache miss? Should these be set by the operator? Would be good from an operational point of view to provide some more details related to caching. Jim> yes agreed. We will add a section and would appreciate your input. - Section 4, The behavior of remembering the SR stack occurs at the end of the regularly defined logic. The behavior of reattaching the stack occurs before the SR process of forwarding the packet to the next entry in the segment-list. Both behaviors are further detailed in section 5. The SR stack reads as SR-MPLS specific. Can this be generalized or perhaps text added for SRv6 as well? Jim> I am not sure where (or what text) to add to make this clearer. Do you have any suggestions? - Section 5, path-id is not used anywhere else; should it be mentioned that this is Service Path Identifier (SPI)? Jim> yes and I will update the text thank you. - Suggest adding a backward compatibility section to describe what is likely to happen if an SFF does not support "Integrated NSH Service Plane" but receives an NSHoSR packet. Jim> I will try to add some text. Nits - Remove references in the Abstract Jim> done - Should there be some reference to 3GPP in the first paragraph Section 1.1? Jim> do you have a suggested reference/s ? - Section 5, s/RFC 8754/[RFC8754] Jim> done. Note - There are 2 cases of Normative reference to Informational RFCs: RFC 8596 and 7665. Need to handle Downref registry during IETF LC. Thanks!

Thanks Greg for the review. To allow for more feedback, the WG last call is extended for two weeks until March 18. In the meantime, authors are invited to reply to the comments sent on the list.

After review of the document please indicate whether you believe this document should be progressed to the IESG. In addition to yes/no, please consider providing a technical review of this document; in particular if you care for this document. Indeed, since WG adoption, this document had benefited from little reviews from the WG, so we need more review from the SPRING WG. If you are aware of an implementation of this document, please report the implementation either on the list or to the chairs so that the shepherd can report implementations in the writeup. Note that I'll forward that call to the SFC WG. Thanks!
