[Sis-dtn] Re: CCSDS MOIMS MO on ESA METERON OPSCOM-2 and DTN

[Vint Cerf]

Keith, et al,

It would be most helpful to have a summary report illustrating the role DTN
played and how its performance features supported this application. I would
love to begin building a catalog of technical papers and TRL-building
demonstrations for use in discussions about research investment policy.
