All things related to multicast

["Fligor, Debbie" <>]

We’ve gotten stuck supporting SVSI multicast AV units, and they are breaking 
things all over the place.

http://svsiav.com/video-over-ip-products/encoders/

The vendor’s solution is that we should have a parallel physical network just 
to support AV on campus, and not mix the traffic with our real network, 
because they should only use “light compression” on their video.

They spew multicast packets so fast that they’ll overwhelm 1G uplinks between 
switches (we have plenty of smaller buildings that don’t actually need 10G 
links between the switches yet - or they didn’t)

It also appears that they need a unique multicast group address per video 
encoder.  We’ve been asked for 60 just for one building on campus that is 
putting in a video wall. With over 350 buildings on campus, that would use up 
a large part of 239.255.x.y just for this one application.

If anyone has ideas on how to get them using SSM, or has successfully gotten 
them to play nice on their data network, any info is appreciated.

Ideas for convincing the vendor to use modern multicast and 
encoding/compression are welcome as well!


Thanks,
