The IESG has received a request from the Protocol Independent Multicast WG (pim) to consider the following document: - 'Population Count Extensions to PIM' <draft-ietf-pim-pop-count-06.txt> as Experimental RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2012-06-12. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This specification defines a method for providing multicast distribution-tree accounting data. Simple extensions to the PIM protocol allow a rough approximation of tree-based data in a scalable fashion. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-pim-pop-count/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-pim-pop-count/ballot/ No IPR declarations have been submitted directly on this I-D.
