Abstract

A multi end-point (EP) conferencing system, including a decentralized scalable network of End-Points that includes a source EP being configured to connect to a non-virtual target EP. The source EP being configured to transmit to the non-virtual target EP a conference list thereof, for distributing to non-virtual EPs and virtual EPs associated with the target EP. It is further configured to receive a conference list of the non-virtual target EP, integrate the received conference list with its conference list to obtain an integrated conference list and distribute the integrated conference list or parts thereof to virtual EPs and non-virtual EPs associated with the source EP. The source EP being further configured to receive a positive selection notification being indicative of a requesting EP from EPs associated with the source EP that would like to get data from the source EP. In response to receipt of the positive selection notification, the source EP being configured to transmit data for receiving by the requesting EP.

11. The multi end-point (EP) conferencing system of claim 10, wherein the source EP is further configured to utilize the integrated conference list for selecting an EP from among a group of identified EPs identified as associated with the source EP utilizing a criterion of number of EPs receiving the output data from the group of identified EPs, such that the selected EP has the largest number of EPs receiving the output data.

12. The multi end-point (EP) conferencing system of claim 10, wherein the source EP is further configured to:

utilize the integrated conference list to identify a non-virtual EP that at least one of the positively

selected EPs is associated with, and transmitting to the non-virtual EP a positive selection notification for distributing to the positively selected EPs;

receive conferencing data originating from the positively selected EPs; and

mix and output the received conferencing data originating from the positively selected EPs.

13. The multi end-point (EP) conferencing system of claim 12, wherein the source EP is further configured to receive at least one multi-cast IP address and port number of the positively selected EPs and receive data from other EP nodes using the multi-cast IP address and port number.

14. The multi end-point (EP) conferencing system of claim 10, wherein the source EP is further configured to receive conferencing data using a uni-cast protocol from a non-virtual EP, wherein the conferencing data originated from the positively selected EPs.

15. A method for communicating data, comprising:
