Multicast traffic % in enterprise network ?

["Mankamana Mishra \(mankamis\) via NANOG" <nanog () nanog org>]

Hi Every one,
Recently we had good discussion over multicast uses in public internet. From discussion, it was pointed out uses of 
multicast is more with in enterprise.  Wanted to understand how much % multicast traffic present in network

  *   If there is any data which can provide what % of traffic is multicast traffic. And if multicast is removed, how 
much unicast traffic it would add up?
  *   Since this forum has people from deployment area, I would love to know if there is real deployment problems or 
its pain to deploy multicast.


These questions is to work / discussion in IETF to see what is pain points for multicast, and how can we simplify it.



Thanks
