Hi All We are doing some work on providing 'protected' multicast for AG nodes as well as other multicast services. Two things:
1) If anyone has had performance issues related to multicast we'd be very interested to hear about them, especially if they are campus related. Also if you have 'protected' your multicast in any way by using topology or traffic engineering (VLAN, QoS) that would be interesting. 2) Also, we have packet dump data for AG conferences, in order to look at packet burstiness etc, but would like some more just to be sure we have a representative sample. If there is any chance that you could provide data such as that from a: snoop -r -tr -S [group address] or tcpdump -n host [group address] i.e. basically with: timestamp, IP source, Group destination, packet length These packet traces would be very useful to confirm our current data. Info from test sessions, or from real conferences, would be useful - with anything from two to 20 participants. None of the data given will be made public - just the summary info. Please state how many participants and the bandwidth used if possible. The trace need only be 10 to 15 seconds long... The final document will be publicly available of course...
