Hi Gyan, This document does not even “update” the LSR Flex-Algo draft since it is introducing something new and on top. It does not change what’s in the LSR Flex-Algo draft.
This document would be pretty much independent and an optional/add-on element on top of the LSR Flex-Algo solution.

So this draft defines a new Adj-Sid that has an Algo identifier specifically for Flex Algo and if that’s the case I agree it does not update the SR-MPLS IGP extensions, but instead should update the Flex Algo extensions.

This draft fills the gap where multiple algorithm identifiers are associated with a link applied to prefix sid and to add parity as now this draft provides Algo association with the adjacency SID as well. At the end of the introduction is stated that the algorithm identifier should be included as part of the adjacency SID advertisement for SR-MPLS. What about SRv6? [PSF] For SRv6, tt was born with this ability, since SRv6 END.X SID can be allocated from an algorithm specific Locator. Does this draft update the SR IGP extensions for SR-MPLS RFC 8665 8666 8667. [PSF] Yes. Also does it update the Flex Algo draft? https://datatracker.ietf.org/doc/html/draft-ietf-lsr-flex-algo-16 [PSF] No. In section 5 operations describes how flex Algo plane can now be differentiated on the same adjacency link with the Algo identifier adjacency sid to Algo plane can now have QOS and link resources characteristics defined which maybe beneficial to TEAS network slicing application as well as used in conjunction with a resource sid for underlay resource provisioning for Enhanced VPN overlay. [PSF] Agree. Flex-algo can be used alone as a network slicing mechanism for some limited scenarios, and adj-sid per algo provide a basis for this purpose. However this is outside the scope of this document, so it is not described in detailed.
