It's taken a while for spraying and trimming to go from being a crazy research idea to mainstream in UEC, but if you're interested, the old animations from my Sigcomm 2017 talk still give the general idea: https://www.youtube.com/watch?v=BO0QhaxBRr0 https://www.youtube.com/watch?v=BO0QhaxBRr0
In addition to what is in the video, UEC introduces a new libfabric-based transport layer and a new congestion control scheme. Plus a bunch of stuff at the lower layers like link-layer retransmit. Hopefully the specs will reach 1.0 around the the end of the year - unfortunately at the moment you can only get them if you're a member of UEC.
- ZWoz 2y agoThat name NDP looks little bit confusing. For example, wikipedia article https://en.wikipedia.org/wiki/Neighbor_Discovery_Protocol https://en.wikipedia.org/wiki/Neighbor_Discovery_Protocol shows NDP as Neighbor Discovery Protocol, even when RFC-s themselves don't use that abbreviation.
- mhandley 2y agoYes, it was a poor choice of name. It was originally just a placeholder in the htsim code, from New Datacenter Protocol, but we avoided choosing a better name for too long and had already talked about it as NDP to enough people (especially research funding people) that we decided it would be confusing to change. With hindsight, we should have changed it earlier. Later on we did change the name of its derivative to EQDS.
