This came up on the fediverse ~18 months ago; here’s what I said at the time:
“Depends on the workload, of course, but it feels like a very comfortable fit. Certainly the vast majority of 9p *messages* on a given network are a small fraction of their “small” threshold. I need to read the paper more carefully; the RPC oriented design sounds promising, but the “at least once” model and no explicit ACKs raises some questions for me. it would be a fun experiment, for sure! Got a datacenter I can try it on? ;-)” Reading the paper more didn’t really answer the questions, and I still haven’t found a datacenter to try it on. > On Sep 21, 2026, at 22:48, Skip Tavakkolian <[email protected]> > wrote: > > I will preface this by acknowledging that I know very little about the > details of the protocol and I could be totally off the mark. > > I only recently found out about Ousterhout's latest project from this > recent talk.
