1.  Introduction

   The aim of this document is to define the functionality that an IGMP/
   MLD proxy with multiple upstream interfaces should have in order to
   support different scenarios of applicability in both fixed and mobile
   networks.  This functionality is needed in order to simplify node
   functionality and to ensure an easier deployment of multicast
   capabilities in all the use cases described in this document.

   Any Source Multicast (ASM) [RFC1112] and Source-Specific Multicast
   (SSM) [RFC4607] represent different service models at the time of
