Abstract

The subject application is directed to a system and method for rapid switching between anycast multicast sources. Multiple streams of data are received by a server. The server associates a separate source address to each of the received streams and sources the multiple streams of data with the associated addresses to a recipient. The server determines whether each of the multiple streams of data is up or down. The server periodically sends status information with the associated address for each of the multiple streams of data to the recipient indicating whether each of the multiple streams of data is up or down.
