 Generic Application Programming Interface (API) for Window-Based Codes
                  draft-roca-nwcrg-generic-fec-api-00

Abstract

   This document introduces a generic Application Programming Interface
   (API) for window-based FEC codes.  This API is meant to be usable by
   any sliding window FEC code, independently of the FEC Scheme or
   network coding protocol that may rely on it.  This API defines the
   core procedures and functions meant to control the codec (i.e.,
   implementation of the FEC code), but leaves out all upper layer
   aspects (e.g., signalling) that are the responsibility of the
   application making use of the codec.  A goal of this document is to
   pave the way for a future open-source implementation of such codes.
