Hi,

On 2017-10-29, at 8:01, Simon Pietro Romano <spromano@unina.it> wrote:
> The sad thing about multipath is that there have been people who have worked, more than one year ago, on implementing it in a v1-compliant way. Though, the group has never wanted to give multipath a real chance to survive and has always treated it as a “potential future extension”. This has been made so clear in the mailing list that we have stopped trying to push for it.

I don't think that's a fair summary.

First, there is no v1. We're busy specifying it at the moment, and many, many fundamental things are still changing. These are taking all the cycles the WG has at the moment, and we're still not progressing at a satisfactory pace. (Which was the message that started this thread.) I also don't think that the implementations are at a stage where they can realistically think about adding multipath - most haven't even really looked at recovery in detail.

Multipath *is* in the charter, and we're fully committed to supporting it. I simply can't see how getting the WG working on the details at multipath at this time will help speed up work on the protocol fundamentals. And it seems that we'd need to continuously rework multipath while we're still changing protocol fundamentals, which would create additional busy work.
