Abstract
The present invention is directed to systems and methods for efficient and effective multicast delivery over hub and spoke networks, including satellite-based hub and spoke networks. In one embodiment, a method of establishing a multicast connection with a plurality of receiving stations includes receiving with a gateway port a unicast connection, such as a TCP connection, from a sending station, mapping the unicast connection to a multicast connection on a first multicast group IP address, and initiating the multicast connection to a plurality of receiving stations. In alternative embodiments, the multicast connection is established over a satellite link, and/or is unidirectional.
