"The RPF Vector TLV", IJsbrand Wijnands, 20-Oct-08. ( bytes)
- This document describes a use of the PIM Join Attribute as defined in
draft-ietf-pim-join-attributes [I-D.ietf-pim-join-attributes] which
enables PIM to build multicast trees through an MPLS-enabled network,
even if that network's IGP does not have a route to the source of the
tree.

"Authentication and Confidentiality in PIM-SM Link-local Messages", William Atwood, Salekul Islam, Maziar Siami, 3-Nov-08. ( bytes)
- RFC 4601 mandates the use of IPsec to ensure authentication of the
link-local messages in the Protocol Independent Multicast - Sparse
Mode (PIM-SM) routing protocol. This document specifies mechanisms
to authenticate the PIM-SM link local messages using the IP security
(IPsec) Authentication Header (AH) or Encapsulating Security Payload
(ESP). It specifies optional mechanisms to provide confidentiality
using the ESP. Manual keying is specified as the mandatory and
default group key management solution. To deal with issues of
scalability and security that exist with manual keying, an optional
automated group key management mechanism is specified.

"Population Count Extensions to PIM", Dino Farinacci, Greg Shepherd, 28-Jul-08. ( bytes)
- This specification defines a method for providing multicast
distribution-tree accounting data for billing and debugging. Simple
extensions to the PIM protocol allow a rough approximation of tree-
based data in a scalable fashion.

"A Reliable Transport Mechanism for PIM", Dino Farinacci, IJsbrand Wijnands, Apoorva Karan, A Boers, Maria Napierala, 22-Aug-08. ( bytes)
- This draft describes how a reliable transport mechanism can be used
by the PIM protocol to optimize CPU and bandwidth resource
utilization by eliminating periodic Join/Prune message transmission.
This draft proposes a modular extension to PIM to use either the TCP
or SCTP transport protocol.

"PIM Group-to-RP Mapping", Bharat Joshi, Andy Kessler, David McWalter, 21-Oct-08. ( bytes)
- Each PIM-SM router in a PIM Domain which supports ASM maintains
Group-to-RP mappings which are used to identify a RP for a specific
multicast group. PIM-SM has defined an algorithm to choose a RP from
the Group-to-RP mappings learned using various mechanisms. This
algorithm does not allow administrator to override a specific Group-
to-RP mapping with the static Group-to-RP mapping which an
administrator would want to use. This algorithm also does not
consider the PIM mode and the mechanism through which a Group-to-RP
mapping was learned.
The intention of this document is to suggest a standard algorithm to
deterministically choose between several group-to-rp mappings for a
specific group. This document first explains the requirements to
extend the Group-to-RP mapping algorithm and then proposes the new
algorithm.
