НАСА и ЕКА успешно протестировали межпланетный интернет на МКСNASA and the European space Agency (ESA) has successfully tested the transfer of data from the ISS to the Earth with interplanetary Internet new data transfer Protocol that will be used during the expeditions into space, the press service of the space Agency.

In the experiment, the health check of the new Protocol DTN (Disruption-Tolerant Networking) ISS commander Sanita Williams (Sunita Williams) ran from the orbit of a small robot from parts of the designer "LEGO", which is located in the European mission control center in the German city of Darmstadt.

"Experimental Protocol DTN, which we tested on the orbital station, in the future can be used by people on Board the spaceship to near Mars orbit to manage the machines on the surface of the planet," said Badri Younes (Badri Younes, Deputy administrator on systems of navigation and communication NASA.

The architecture of the Protocol DTN provides a standardized data exchange procedures, similar to the "earthly" to the Internet. Unlike the Internet Protocol TCP/IP, which implies a constant connection, the Protocol DTN designed to interruptions, errors and delays.

The signal is transmitted on the principle of "step by step" - if the site cannot transmit a data packet on purpose, information is not deleted, but stored. Attempts transmission continues until until network node cannot communicate with any other node and successfully pass data. Ultimately, information finds the recipient.

First trials of a new Protocol held in November 2008, when NASA successfully passed about a dozen photos on Board the probe "Deep Impact" (Deep Impact), who was at that time at 32 million kilometers from Earth.
