Solar System Internet

Info:

Solar System Internetwork (SSI) is being designed to allow a standardized way spacecrafts, satellites, crew, exporting robots, and even planets communicate:

Space missions need a reliable way to communicate reliably. However networking in-between planets is subjected to various disruptions and delays. As a planet rotates, ground stations will lose communications with spacecrafts or satellites on other planets (such as Mars). Even the Sun itself can block planets as they rotate on different sides on the Sun. Delay/Disruption Tolerant Networking (DTN) is a network that has frequent Disruptions or long Delays in the connection between the network devices. Using a Store and Forward technique, application data is bundled together and stored locally at each node and then forwarded to the next node when access is available.

NASA, Harvard & TopCoder Partner are Developping a Secure Solar System Internet Protocol. Details on the TopCoder DTN Project to allows you help NASA with their Interplanetary Internet.

The InterPlanetary Networking Special Interest Group (IPNSIG) has a DTN Tutorial explain how a DTN can be used to form an Interplanetary Internet. The Interplanetary Overlay Network (ION) software distribution is an implementation of Delay-Tolerant Networking (DTN). IOAG Space Internetworking Strategy Group (SISG) & Space Internet Architecture Group (SIAG) has Information on a Recommendation on a Strategy for Space Internetworking and also Operations Concepts for a Solar System Internetwork.
