NASA’s Disruption Tolerant Networking Challenge Series
October 24, 2013

[image-51]The NASA Tournament Lab (NTL) is continuing its series of challenges to develop data networking protocols that can extend our internet into the Solar System. Building on the prototype implementations of the Disruption Tolerant Networking (DTN) protocol suite, these challenges will help improve the security, performance, and application of network protocols that can withstand the time delays due to the immense distances between planets and the disruptions and non-contiguous paths of the space communications links. The first 4 challenges have been posted on TopCoder as part of NASA’s contract with Harvard and TopCoder. The first 2 challenges dealing with the verification of the DTPC protocol and development of the LTP authentication protocol are both successfully completed.  The 3rd in the series is the Key Management challenge, which launched last October.  This challenge is seeking to solve the particularly difficult problem of managing security key information across a set of nodes that may be connected with delayed or disrupted/unreliable communications links.   This challenge will run through early July.   The 4th and latest challenge in the series launched on April 23rd and is focused on adapting the astronaut’s email on the ISS to use DTN.
