Near Earth Application of Delay/Disruption Tolerant Networking in Operational Networks

Completed Technology Project

Project Introduction

In this internet age when a user sends an email to another user, rarely if at all do we think about the thousands of connections/links that exist in order for our email to arrive at another user’s inbox.  In like manner, DTN for space communications allows data to be transmitted to one node to another independent of whether or not there is a current data connection. DTN allows for an internet-like approach to spacecraft communications.  The idea of this effort is to achieve technology maturation of exiting DTN implementations to allow for a clear infusion pathway for ground and flight use of DTN in operational systems.
