Where is multicast implemented?

I am just curious, in the real world, how and where is multicast implemented?

Is it mostly inside a corporation's network only? Can a home user be able to tune into any multicast stream from their DSL or Cable connection?

  • Well, I had many customers with Mcast in their LANs (quite recently a bank)- mostly Video traffic. Also remember a couple of customers with sort of "Mcast based file publishing" apps. Also know some global implementations of Mcast...

    The idea's been around since ages ago:

    Thanks for the reply.

    If company A has muticast implemented in their LAN and then one of its partner company B wants to join their multicast group, how can that be done?

    Thanks!

  • VG,

    I work more on the troubleshooting side of the world ;) but I would imagine it's basically associated with their policies. I believe in joint projects MSDP is used but in a provider model I would say Sparse with manual RP setting. But to be honest never  been involved in Mcast design cases :) - by the way not eveyone in the world has a Cisco shop!

  • I see it mostly 'enabled' in the network. Both Enterprise and SP networks, but it's hardly used or entirely not used. But a lot of networks are 'prepared' :-)
