Abstract
A method of propagating multicast subscription and routing information between routers in a network, and constructing forwarding tables in the routers, allowing providers of the data (the publishers), and the multicast recipients of the data (the subscribers) to be decoupled from and have no knowledge of one another. This is done without the need to maintain (Source Network, Published-Multicast-Group) State in the routers, for a highly scalable solution in those applications where there is a possibility for a large, or infinite number of Published-Multicast-Groups, and in those applications where messages are being routed by content, so it is impossible to identify published-multicast-groups.
