Abstract

   This memo presents the current deployment of network coding in some
   satellite telecommunications systems along with a discussion on the
   multiple opportunities to introduce these technics at a wider scale.

1.  Introduction

   Network coding schemes are inherent part of the satellite systems,
   since the challenging physical layer require specific robustness to
   guarantee an efficient usage of the expensive radio resource.
   Further exploiting these schemes is an opportunity for a better end
   user experience along with a better exploitation of the scarce
   resource.

   In this context, this memo aims at:

   o  summing up the current deployment of network coding schemes;

   o  identifying opportunities for further usage of network coding in
      satellite systems.
