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."
