Abstract
This disclosure is directed to techniques for communicating in an adaptive multicast network. In general, the disclosure is directed to communicating in an adaptive multicast network. This may be done by archiving, at a rendezvous point, multicast subscription information for terminal nodes in the adaptive multicast network, 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. A router receives a multicast stream from a sender terminal node. The router receives the multicast subscription information for the multicast stream sent by the sender terminal node from the rendezvous point. The router forwards 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.
