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.
