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.
Claims9
A method of establishing a multicast connection with a plurality of receiving stations, said method comprising:
- receiving a unicast, transport layer connection request from a sending station;
- wherein the unicast connection request includes a transport layer port identifier;
- establishing a unicast, transport layer connection with the sending station;
- mapping, using the transport layer port identifier, said unicast, transport layer connection request to a multicast connection on a multicast group network address;
- and
- initiating, in response to said unicast, transport layer connection request, said multicast connection to a plurality of receiving stations;
- wherein the unicast, transport layer connection and the multicast connection provide for the detection and retransmission of lost or corrupted data;
- wherein said multicast connection comprises a XTP connection.
