 Requirements for the extension of the IGMP/MLD proxy functionality to
                  support multiple upstream interfaces
               draft-ietf-pim-multiple-upstreams-reqs-08

Abstract

   The purpose of this document is to define the requirements for a MLD
   (for IPv6) or IGMP (for IPv4) proxy with multiple interfaces covering
   a variety of applicability scenarios.  The referred scenarios, while
   describing not sophisticated service situations, present cases that
   existing technology does not allow to solve in a simplistic manner.
   This document is then intended to serve as input for future documents
   defining the support of multiple upstream interfaces by IGMP/MLD
   proxies being compliant with the aforementioned requirements.
