Abstract

   This document summarizes a recommended terminology for Network Coding
   concepts and constructs.  It provides a comprehensive set of terms in
   order to avoid ambiguities in future Network Coding IRTF and IETF
   documents.  This document is intended to be in-line with the
   terminology used by the RFCs produced by the Reliable Multicast
   Transport (RMT) and FEC Framework (FECFRAME) IETF working groups.

1.  Introduction

   The literature on Network Coding research and system design, IETF
   included, led to a rich set of concepts and constructs.  This
   document collects terminology used in the domain, both outside and
   inside IETF, provides concise definitions, and introduces a high
   level taxonomy.  Its primary goal is to be useful to IETF and IRTF
   activities.  It is also intended to be in-line with the terminology
   already used by the RFCs produced by the Reliable Multicast Transport
   (RMT) and FEC Framework (FECFRAME) IETF working groups, in particular
   [RFC5052] [RFC6726] [RFC5775] [RFC5740] [RFC6363].

   This document only focuses on packet transmissions and packet losses,
   for instance because of congested routers, routing issues,
   intermittent connectivity (e.g., a mobile terminal can suddenly go
   behind an obstacle) and wireless communication issues.
   Communications may happen in various types of networks, physical
   links, UDP services, overlay networks or even virtual networks.  The
   notion of packet itself is multiform, depending on the target use-
   case and the way network layer is applied (e.g., in which layer of
