List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 24 Jul 2021 17:02:55 -0000 One of our newer members is one of the authors of this: https://people.cs.rutgers.edu/~sn624/papers/ccp-sigcomm18.pdf I will reserve comment for now. I don't grok the intersection with ebpf as = yet. Please? newer folk here, please briefly introduce yourselves and your interests in starlink's stuff? I very much approve of lurkers - even aliases! for those that cannot talk due to various NDAs, etc, but... For those here that don't know me already, well, I'm this renegade that has long lived outside of the vogon-industrial-military-academic complex with more key open source networking contributions to the world than most. These days I'm best known for the bufferbloat project and multiple congestion control algorithms/packet schedulers and AQ= Ms ( Please put a copy of https://bufferbloat-and-beyond.net/ in your reading queue) but I have a long history going back to 1982 of kicking the tires of the internet, creating a RUD, and then fixing it. My own personal mission (as per the podcast) is to merely see starlink get sch_cake up on outbound on the dishy but long term I care a lot about just about anything networked and in space from here out to the edges fo the solar system. I'm really low on spare time at the moment personally, but if newer folk here would like to introduce themselves and point a link at a key paper of theirs or at their work in progress, perhaps the conversation will get rolling a bit more. We're still looking for more folkable to do our measurement suite in particular. (we also need to put up the mailing list archive so far for new folk. Am short an mailman expert for that if anyone has those chops?) --=20 Fixing Starlink's Latencies: https://www.youtube.com/watch?v=3Dc9gLo6Xrwgw Dave T=C3=A4ht CTO, TekLibre, LLC
