All things related to multicast

[Bob Gerdes <>]

Greetings,
    In previous exchanges, there have been discussions regarding 
implementations of multicast on various wireless networks (one noted 
below). In another, folks were going to check with specific vendors.

    We are looking for any cases where multicast (especially multiple IPTV 
channels) has been implemented on a wireless network for mobile users.

    In checking with different vendors, we had a conversation with a 
distributor who is suggesting that wireless vendors are implementing a 
streaming service to redistribute a multicast stream. In another, 
apparently some folks have had some success with Aruba, but haven't gotten 
followup info yet. So, hopefully you might have some better experiences or 
updates since last year.
     Thanks for your considersation,
       Bob

Backgroud: our group is working with our TV group on an IPTV pilot service 
using VideoFurnace/Haivision servers. We have been working with our 
networking group to get multicast working across campus. Our Wireless 
group uses Meru access points and BlueSocket for authentication and 
policy, but they have not been able to make progress with multicast on 
Wireless. One issue is that we would need to move the infrastructure to 
802.11N or better.
