Question : Problem: Multicast Performance

Hi,
I am interested in setting up a multicast network(video surveillance) however I am deciding which would be better; pim-dense or pim-sparse. In term of camera receovery from network outage(example switch doing a fail-over when video cameras are running multicast); which multicast protocol would provide a better performance ?
As I am new multicast, would anyone be  advise/provide some guidelines?

Thanks.

Answer : Problem: Multicast Performance

Sparse and Dense Modes are defined basically on the basis of number of multicast receivers on any network.
A dense mode assumes that the number of receivers are large and sparse mode assumes that receivers are few.

In multicast, you have to define a interface taking part in multicast activity. So, as per the number of interfaces taking part you may define the PIM mode.

Hope this clarifies ...
