Reliability in overlaid multicast networks

One of the issues in overlaid multicast networks is reliability of multicast communications. sudden tunnel failures, node failure, degradation of tunnel may lead to failure or degradation of the communications. In such scenarios, what signalling protocols can be implemented for reconfiguring the overlaid multicast topology for reliability. How the proposed algorithms will perform? We need to decide on the performance criterion also.
