Network coding for satellite systems
draft-irtf-nwcrg-network-coding-satellites-14
Abstract
This document is one product of the Coding for Efficient Network
Communications Research Group (NWCRG). It conforms to the directions
found in the NWCRG taxonomy.
The objective is to contribute to a larger deployment of network
coding techniques in and above the network layer in satellite
communication systems. The document also identifies open research
issues related to the deployment of network coding in satellite
communication systems.

1. Introduction
This document is one product of and represents the collaborative work
and consensus of the Coding for Efficient Network Communications
Research Group (NWCRG); while it is not an IETF product and not a
standard it intends to inform the SATellite COMmunication (SATCOM)
and Internet research communities about recent developments in
Network Coding. A glossary is included in Section 6 to clarify the
terminology use throughout the document.
As will be shown in this document, the implementation of network
coding techniques above the network layer, at application or
transport layers (as described in [RFC1122]), offers an opportunity
for improving the end-to-end performance of SATCOM systems. While
