TCP is already out as a protocol for our galactic internet, see relevant comment from Linux TCP implementation:
/*
* [...] Note that 120 sec is defined in the protocol as the maximum
* possible RTT. I guess we'll have to use something other than TCP
* to talk to the University of Mars.
* PAWS allows us longer timeouts and large windows, so once implemented
* ftp to mars will work nicely.

- dave1010uk 15y ago(This is from /usr/src/linux/net/inet/tcp.c) This is correct. At their furthest apart, Mars and Earth are 22 light minutes apart. Their closest is almost exactly 3 light minutes. For comparison, the Earth and Moon are just over 1 light second apart. On a more serious note, could tcp.c just be patched on the client to drop packets after ~10sec?
- mooism2 15y agoI sincerely hope ftp is a distant memory by the time the University of Mars opens.
- cpeterso 15y agowell, why not? Martian students will need to use something to transfer files. Perhaps SFTP? The International Space Station still uses Kermit! At least they did in 2003: http://www.spacedaily.com/news/iss-03zq.html http://www.spacedaily.com/news/iss-03zq.html
