Abstract

   This document specifies protocol independent multicast- Next
   generation or simply called PIM-NG. PIM-NG uses the underlying
   unicast routing information, but unlike PIM-SM it doesn't necessarily
   need to build unidirectional shared trees rooted at a Rendezvous
   Point (RP) per group, due to the fact that the processes through
   which a source registers with the Rendezvous Point and a host finds
   the source of the multicast destination groups it needs are done in a
   whole new way and hence, the source of multicast group (G) is
   discovered faster. So at some points PIM-NG works faster than its
   predecessor. Also the new Domain concept, unique to PIM-NG, along the
   RPF check method used in PIM-NG specifications provides many features
   along a robust and flexible control and administration over multicast
   networks.
