                  Network coding for satellite systems
             draft-irtf-nwcrg-network-coding-satellites-08

Abstract

   This document is the product of the Coding for Efficient Network
   Communications Research Group (NWCRG).  This document follows the
   taxonomy document [RFC8406] and considers coding as a linear
   combination of packets that operate in and above the network layer.
   In this context, this memo details a multi-gateway satellite system
   to identify use-cases where network coding is relevant.  As example,
   network coding operating in and above the network layer can be
   exploited to cope with residual losses or provide reliable multicast
   services.  The objective is to contribute to a larger deployment of
   such techniques in SATCOM systems.  This memo also identifies open
   research issues related to the deployment of network coding in SATCOM
   systems, such as the interaction between congestion control and
   network coding techniques.

Status of This Memo

   This Internet-Draft is submitted in full conformance with the
   provisions of BCP 78 and BCP 79.

   Internet-Drafts are working documents of the Internet Engineering
   Task Force (IETF).  Note that other groups may also distribute
   working documents as Internet-Drafts.  The list of current Internet-
   Drafts is at https://datatracker.ietf.org/drafts/current/.

   Internet-Drafts are draft documents valid for a maximum of six months
   and may be updated, replaced, or obsoleted by other documents at any
   time.  It is inappropriate to use Internet-Drafts as reference
   material or to cite them other than as "work in progress."
