The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-mls-architecture/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- Thanks for the work on this document. Many thanks to Valery Smyslov for his ART ART review: https://mailarchive.ietf.org/arch/msg/art/uoBsyBurn4jzZu_AGqADSa-Jpx0/, also reported below. I have only had time to scan the document and haven't found any ART issues with it. However, I hope Valery's review can be addressed before the document is moved forward. 1) It is not clear from the document if it is ever possible for clients that support only version x of the protocol to join the group that was formed using version y of the protocol, but in fact all the current members of this group support both versions. It seems to me that this scenario is common in situations when newer version of the protocol becomes available: during some period of time some clients will support both new and old version, while the rest will support only old version. If some upgraded clients form a group, they will probably choose the newest version of the protocol, so the un-upgraded clients won't be able to join it. I think that this scenario should be addressed in the document. 2) It is still not clear for me whether the type of DS (Strongly Consistent vs Eventually Consistent) affects clients that use this DS. In other words - does clients' behaviour depend on the type of DS or not, and if yes, then how it is handled in the protocol. 3) The issue of inability for a client to remove itself from the group by itself seems unsolvable. I would like to see recommendations in the document for clients wishing to exclude themselves in situations when other members for some reasons don't cooperate in this process.
