Internet-Draft           Survey Report on PIM-SM               June 2013

1.  Motivation
1.1.  Overview of PIM-SM

   PIM-SM was first published as [RFC2117] in 1997 and then again as
   [RFC2362] in 1998.  The protocol was classified as Experimental in
   both of these documents.  The PIM-SM protocol specification was then
   rewritten in whole and advanced to Proposed Standard as [RFC4601] in
   2006.  Considering its multiple independent implementations developed
   and sufficient successful operational experience gained, the PIM WG
   decided to advance the PIM-SM protocol to Internet Standard and the
   survey and this document are part of the work.
