Hi Greg,

I agree that multicast is an important use case to cover for any telemetry technique.
In our draft, https://tools.ietf.org/html/draft-song-multicast-telemetry-00, we also discussed the on-path multicast telemetry techniques that combine both IOAM and PBT for efficient multicast support.

Regards,
Haoyu

Dear All,
the new version of the Hybrid Two-Step draft includes the new section on the use of HTS in a multicast network. The goal is to avoid unnecessary replication of telemetry information collected on-path while multicast data packets traverse a multicast distribution tree. At the same time, a centralized controller should have sufficient information associated with collected telemetry information to reconstruct the state of the traversed multicast path based on HTS packets.
 Much appreciate your comments, questions, and suggestions.

Regards,
Greg

Abstract:
   Development of, and advancements in, automation of network operations
   brought new requirements for measurement methodology.  Among them is
   the ability to collect instant network state as the packet being
   processed by the networking elements along its path through the
   domain.  This document introduces a new hybrid measurement method,
   referred to as hybrid two-step, as it separates the act of measuring
   and/or calculating the performance metric from the act of collecting
   and transporting network state.
