Re: [rmcat] New Version Notification for draft-hayes-rmcat-sbd-01.txt

[Simone Ferlin-Oliveira <[e-mail]>]

Thanks Michael for the review.

Regarding your last two comments:
2. Yes, I am working on the implementation with/for MP-TCP at the moment.
3. I am figuring this out. At the moment, we have the algorithm
running in user-space to test, but it will go to the kernel at some
point. I will do this for Linux, would you (or somebody with you) be
interested to do it for SCTP?

Thanks again,
Simone
