Abstract

   Delay/Disruption Tolerant Networking (DTN) is designed for a severe
   environment where communication quality is not guaranteed. It works
   as an overlay network associated with Bundle Protocol (BP) and some
   convergence layer protocols like Licklider Transmission Protocol
   (LTP). DTN is suitable for satellite networks. Because communication
   delay is long and peer-to-peer communication is not guaranteed in
   satellite networks. We implement SDN to solve the problems of
   controllable, manageable, and flexible in satellite networks. In
   this document, we propose a framework of Software Defined DTN-based
   satellite networks, using Bundle tunnel and protocol translation
   gateway.
