List-Id: General list for discussing Bufferbloat Archived-At: List-Archive: List-Help: List-Owner: List-Post: List-Subscribe: List-Unsubscribe: Watching all the neat stuff coming from the Artemis2 mission it occurred to me: are they using SQM techniques and/or CAKE for these links? Might really help with live video and latency sensitive stuff while they are bulk moving things around. Maybe they have old school QOS/COS stuff to absolutely reserve some channels? Or even dedicated links for different things. They can just throw resources at the problem (although I would argue some SQM would _always_ help, they are probably always BW constrained). One thing I watched mentioned them testing a laser based connection that could do something like 260mbit. They also did ship-to-ship with ISS which is cool! Also in addition to ship-to-ground, SQM on the ground relay links would be good (but again they are likely throwing dedicated reserved infrastructure at it). Just my totally naive wondering. I would love to see a presentation of the details by the people working on it! I think that would be a huge PR win in generating more excitement for the program.
