OPTIMIZING USER EXPERIENCES OF WEB CONFERENCES THAT SEND DATA WITH SOURCE-SPECIFIC MULTICAST AND AUTOMATIC MULTICAST TUNNELING

Techniques are presented herein for a multicast server to group receivers, or user devices, with other receivers having similar characteristics, so that the group can be paired with source-specific multicast channel that is optimized specifically for the receivers of the group. The server receives information regarding hardware and network capabilities from each of the user devices. The server then groups the user devices according to their information, where each group contains user devices having hardware and network information that is similar to one another. The server then receives, at random intervals, network reports that are generated by at least one user device from at least one of the groups, where the network reports include information related to the network performance experienced by a user device. The server then adjusts the SSM channel associated with the group of user devices based on the information in the network report.
