It’s really hard to cache content pre-emptively.
Netflix uses multiple Gbps per cache node during off hours to refresh content in order to get decent hit rates.
And Netflix is just one service with a limited content library.
- pencilguin 4y agoThe laser links between satellites may be much less burdened than the uplink from the ground hub station nearest to the subscriber. SpaceX can upload content to the constellation via more-lightly loaded ground hubs, and propagate to the rest. They have the advantage that they can know what was being streamed in an area a satellite is about to enter, and can preload the parts it will need to downlink while there. Of course all this requires intimate cooperation with the streaming service, because it is at a much higher level than packets.
