All things related to multicast

dear macusers ;) all,

as far as i can see ,  IGMPv3 would be very usefull in mobility  
scenarios and i found
all this stuff is integrated into nautilus6

http://www.nautilus6.org/doc/nepl-howto/

I am curiuos if its implemented in the NEW iphone ;)

you need to watch this:

IGMP Version 3 [2] introduces a big enhancement to the previously two
   versions.  It defines INCLUDE and EXCLUDE filter-mode on both the
   host and router side.  Using this filter mode, the host can specify
   the source list information in its group report.

   IGMPv3 router uses filter-mode to process the group record properly.
   The router also maintain a group-timer to indicate the filter mode
   switchover and a source-timer to time each valid source.  A new type
   of Source-and-Group-Specific Query is utilized to verify there are  
no
   receivers desiring to receive traffic from listed sources for a
   particular group, which has been requested to no longer be  
forwarded.

   Another modification is that IGMPv3 does not use host suppression,
   because the various packet type and the diverse information carried
   in the report make it rather difficult to define a uniform
   suppression policy.  Without suppression, the number of packet may
   increase greatly on the subnet.  IGMPv3 solves this problem by make
   pending reports or queries merged into a combined packet.

   An advantage for non-suppression is that it provide the possibility
   for the router to keep the receiving status of each individual
   member, which is known as Explicit Tracking.  The tracking consumes
   much more memory on the router, but provides feasibility to manage
   end users.
