               Protocol Independent (Hardened) Bandwidth
                  draft-hao-rtgwg-ip-hard-pipes-03.txt

Abstract

   This document describes Protocol Independent Bandwidth for IP
   Multicast a.k.a "IP Multicast Hard Pipes".  A hard pipe has a
   dedicated bandwidth that can neither be exceeded or infringed upon.

   RFC 7625 described an implementation of MPLS hard pipes, this
   document discusses the hard pipe technology as applied to IP
   Multicast flows.
