Abstract:
1. A distributed optimization system for multicast data, comprising: a memory: a processor coupled to the memory; a data source on the memory configured as one of multiple video conference members in a multicast video conference, wherein each member in the multicast video conference is a data source communicating video conference data to other video conference members via a communication network, the data source maintaining a complete member list; a multicast tree generated by a local greedy algorithm, wherein the multicast tree is controlled and maintained by the data source; the multicast tree configured to add a new video conference data recipient by determining a least transmission latency to transmit video and audio data from the data source to the new video conference data recipient, wherein when bandwidth is unavailable for the new video conference data recipient, a request to add the new video conference data recipient is queued until the bandwidth becomes available; and an optimization logic generated for each data source in the multicast video conference, configured to:
