            BATS Coding Scheme for Multi-hop Data Transport
                        draft-yang-nwcrg-bats-01

Abstract

   This document describes a BATS coding scheme for communication
   through multi-hop networks.  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 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
