Abstract

   This document introduces a new class of IPv6 multicast addresses
   called "multiple multicast". We define multiple multicast as a set
   of multicast addresses belonging to one multicast session.

1. Introduction

   Multimedia services can use multiple multicast streams [ITU2009]
   which form one multicast session. These services have been provided
   using several multicast groups or one multicast group and user level
   filtering. For services which have been provided using several
   multicast groups this document introduces the new class of IPv6
   multicast addresses called "multiple multicast". We define a
   multiple multicast as a set of multicast addresses belonging to one
   multicast session. Multicast addresses which belong to the one
   multiple multicast address follow the same multicast tree. It allows
   for identical propagation parameters for each transmitted stream
   belonging to one multicast session. It also simplifies multicast
   routing and the management of multiple multicast streams.

   The new class of IPv6 multicast addresses expands the current IPv6
   multicast addressing architecture [RFC4291].
