Dear authors, I like the idea of ACH for SRv6, and I think the use cases make sense and expect to see more if such mechanism exists. However, my opinion is that, since ACH packets are dedicated control packets, it might be easier to encapsulate it in UDP payload while using an SRH flag to indicate the presence of ACH, which is more extensible. In fact, I think this draft can be consolidated with our draft "draft-song-spring-siam-01" for supporting IOAM ins SRv6 https://datatracker.ietf.org/doc/html/draft-song-spring-siam-01 because I can see the potential for ACH6 to become a generic mechanism in SRv6 to support OAM and message passing pertaining to specific SR paths. Look forward more discussions on this!

On one hand, SRv6 SIDs list in SRH provides a certain SRv6 path. On the other hand, ACH6 provides the control and management capability to the SRv6 path.

Title : ACH6 in Segment Routing Authors : Fan Yang Tianran Zhou Filename : draft-yang-spring-ach6-sr-00.txt Pages : 11 Date : 2021-07-12 Abstract: Associated Channel over IPv6 (ACH6) provides a control channel to one specific IPv6 forwarding path for control and management purpose. When ACH6 is used in a Segment Routing network, it provides a control channel to an SRv6 path. This document specifies an SRv6 ACH6 mechanism and describes how ACH6 is applied in a Segment Routing network.
