multicasting

I am working on a project on survivable multicasting.I want to propose a hybrid scheme(protection and restoration) for that purpose.Can anyone help me with an approach to decide protection points in a multicast tree??(The protection points will be those points upto which there will be an alternate path from the multicast source(protection) and from protection point to the multicast destination the path will be dynamically restored.).Pls suggest an approach to find the protection points.I found an approach name caterpillar tree which assigns the nodes on the spine of caterpillar tree as protection points.Is there any other such approach..?

I need to multicast an x11 application window to multiple (sai 100) clients in a lossy (wireless) environment. Right now, I was able to do it through screen grabbing (vlc) and h264 compression, but there should be a cleaner solution, something along the lines of a multicast NX session. Is there… >>> More
