A method for managing multimedia services includes the following steps: A session receiver sends Real-time Transport Control Protocol (RTCP) packets to a distribution aggregation point, and each distribution aggregation point is connected to at least one session receiver and aggregates the received RTCP packets into the first aggregated packet whose format is different from the format of the RTCP packets; the distribution aggregation point sends the first aggregated packet to a distribution source over a transmission network, and the distribution source aggregates the aggregated packet into a second aggregated packet, and then processes the second aggregated packet and transmits it to a session sender, or transmits the second aggregated packet to the session sender directly. The present invention implements feedback of mass packets from the session receiver to the sender in large-scale multicast applications, and avoids the unicast bottleneck.
