            BATS Coding Scheme for Multi-hop Data Transport
                        draft-yang-nwcrg-bats-00

Abstract

   This document describe a BATS coding scheme for communication through
   a multi-hop network.  BATS code is a class of efficient linear
   network coding scheme with a matrix generalization of fountain codes
   as the outer code, and batch-based linear network coding as the inner
   code.

1.  Introduction

   This document specifies a BATS code [BATS] scheme for data delivery
   in multi-hop networks.  The BATS code described here includes an
   outer code and an inner code.  The outer code is a matrix
   generalization of the fountain codes (see also the RapterQ code
   described in RFC 6330 [RFC6330]), which inherits the advantages of
   reliability and efficiency and possesses the extra desirable property
   of being network coding compatible.  The inner code is formed by
   linear network coding for combating packet loss, improving the
   multicast efficiency, etc.  A detailed design and analysis of BATS
