“Interplanetary internet” passes first test
“Images of Mars and its moon Phobos were sent back and forth between computers on Earth and NASA’s Epoxi spacecraft. Instead of TCP/IP a new protocol, named “Disruption/Delay Tolerant Networking” (DTN) was used. Information is only sent once with DTN, and stored at each node until another node is available to receive the information. To prevent hackers from interfering with the network, information that is transmitted over DTN is encrypted. The team at NASA is hoping to get the protocol accepted by the international community and setup a permanent node at the International Space Station next year.”
