Abstract

   This document specifies protocol independent multicast- Next
   generation or simply called PIM-NG. like PIM-SM, 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. 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.
