        Title           : Forward Error Correction (FEC) Framework Extension to Sliding Window Codes

   RFC 6363 describes a framework for using Forward Error Correction
   (FEC) codes with applications in public and private IP networks to
   provide protection against packet loss.  The framework supports
   applying FEC to arbitrary packet flows over unreliable transport and
   is primarily intended for real-time, or streaming, media.  However
   FECFRAME as per RFC 6363 is restricted to block FEC codes.  The
   present document extends FECFRAME to support FEC Codes based on a
   sliding encoding window, in addition to Block FEC Codes, in a
   backward compatible way.  During multicast/broadcast real-time
   content delivery, the use of sliding window codes significantly
   improves robustness in harsh environments, with less repair traffic
   and lower FEC-related added latency.
