The amount of multicast traffic on an enterprise network will depend 
greatly on how multicast is being used, and to some extent, the type of 
business the enterprise is in.

An enterprise that uses multicast primarily for IPTV distribution might 
have different business and technology drivers than, say, a hospital 
or healthcare organization that has patient monitors that use multicast 
to communicate back to a central monitoring station.  The percentage of 
multicast traffic in those two scenarios might be vastly different, but 
no less important to their respective organizations.
