Or would it? Perhaps simply increasing the retransmission timer would give us interplanetary internet. I wonder.

- throwaway9101 13y agoBandwidth delay product tends to limit throughput at such high latencies, though.
- stonemetal 13y agoTCP uses RTT time to try to guess network congestion. Having worked on software that almost always had satellite hops, it sucks on long links. Primarily what you notice is that you get limited bandwidth because the TCP stack is throttling to prevent congestion. Not sure what RTT is to the moon and back but you would want to use something like TCP Hybla that does network congestion control a different way. http://en.wikipedia.org/wiki/TCP_congestion-avoidance_algorithm#TCP_Hybla http://en.wikipedia.org/wiki/TCP_congestion-avoidance_algori...
