Hello, We've submitted a new draft https://datatracker.ietf.org/doc/draft-karboubi-spring-sidlist-optimized-cs-sr/. This draft describes an alternative approach to achieve the circuit-style segment routing policies described in WG document https://datatracker.ietf.org/doc/draft-ietf-spring-cs-sr-policy/ whereby the imposed limitation of having the SID List of such policies encode the full path using only adjacency SIDs is removed. The draft introduces a solution that allows the usage of optimized SID lists (i.e. SID List that may contain non-contiguous node SIDs as instructions) and describes mechanisms that would allow such encoding to still honor all the requirements of the circuit style policies notably traffic engineering and bandwidth requirements. Comments are welcome!

This document introduces a solution that supports circuit style segment routing policies that allows usage of optimized SID lists (i.e. SID List that may contain non-contiguous node SIDs as instructions) and describes mechanisms that would allow such encoding to still honor all the requirements of the circuit style policies notably traffic engineering and bandwidth requirements.
