communication and autonomous operation. Long run of
such architecture may cause unpredictible failure. We, thus,
propose to extend the usage of TemporoSpatial software
defined network for efficient, time-less maintenance (e.g.,
software update). Afterward, we demonstrate the sequence
of the protocol stack and the da'taflow using a case study
(send file from Jupiter to Earth through Mars as a relay
planet). Finally, we evaluate the latency of this case study.
With this paper, we hope to have provided a novel
point of view for future IPN architectures, and set
some foundations for an actual implementation within
the next decades. In future works, we plan to focus on
two concrete aspects of space communication at the
core of our architecture. First of all, we plan to
develop time-dynamic, predictive communication link
modeling, and solar objects' position and velocity
modeling to support TS-SDN and operating links
autonomously in deep space. Furthermore, we aim
at providing a rigorous technical analysis of the costs
and benefits of stationing more inexpensive relay satellites (inspired by CubeSats) at the Earth/Planet-Sun
liberation points. This analysis needs to evaluate the
performance in terms of boosting the signals and
gained data rate.
