Abstract:
1. A method for communicating in an adaptive multicast network, the method comprising: archiving, at a rendezvous point, multicast subscription information for one or more terminal nodes in the adaptive multicast network, wherein the adaptive multicast network is divided into a plurality of trusted networks, wherein the multicast subscription information comprises a dynamic list of receiver terminal nodes located within the adaptive multicast network that subscribe to particular multicast streams from one or more terminal nodes in the adaptive multicast network, and wherein the rendezvous point is a designated router in a first trusted network; receiving, at a router, a multicast stream from a sender terminal node, wherein the router and the sender terminal node are in a second trusted network; receiving, at the router from the rendezvous point, the multicast subscription information for the multicast stream sent by the sender terminal node; and forwarding, from the router, the multicast stream to all receiver terminal nodes in the dynamic list of receiver terminal nodes indicated as subscribing to the multicast stream sent by the sender terminal node.
