Board member Keith Scott provides this update on DTN activities within CCSDS.
CCSDS is in the process of review and approval of two key DTN protocols of particular interest to the InterPlanetary Networking community: the Licklider Transport Protocol and the Bundle Protocol. CCSDS approval will establish LTP and BP as Space Data Systems standards for all member space agencies.
LTP review is pretty much all but done. BP is in its third member agency review, and is scheduled to complete that review in October, 2014.
In other news, deployment of DTN for operational communications between earth and the International Space Station is expected to occur this Fall. The NASA Change Request for deploying DTN for ISS operations was approved in 2013. DTN is already used for most communications between ISS experimental payloads and earth-based researchers and operators.
