Re: [Bloat] DETNET

If you love low latency and high speed, you will be blown away by http://www.cs.cornell.edu/derecho.pdf

The system itself is on GitHub as "Derecho-Project".  Quite useable!  In fact we are still working on some last-steps, so the version there is v0 (maybe two more months before we consider it to be release v1).  We would love to have users who are intent on breaking everything...  all open source, no weird IP or anything, no plan to commercialize it.

I'm notorious for trying to engage other folk slightly outside our circle, thx for carrying on the grand tradition. I do admit it can be quite a lot to get blindsided by!

Well, the overarching goal here is to reduce latencies on everything (hardware, interconnects, busses, drivers, oses, stacks) to the bare minimum, on every technology we can reach, and leverage other ideas in other technologies to do so, whenever possible.

If we had a name for that, other than bufferbloat, I'd switch to it, because we are way beyond just dealing with excessive buffering after 6+ years of operation.

I will got read up on ken's RDMA stuff.
