             Tetrys, an On-the-Fly Network Coding protocol
                     draft-detchart-nwcrg-tetrys-06

Abstract

   This document describes Tetrys, an On-The-Fly Network Coding (NC)
   protocol that can be used to transport delay and loss-sensitive data
   over a lossy network.  Tetrys can recover from erasures within an
   RTT-independent delay, thanks to the transmission of coded packets.
   It can be used for both unicast, multicast and anycast
   communications.
