For each fast channel change, a new RTCP session is initialized, whereas for retransmission, the same RTCP session is always reused, with the same source and destination ports. The RTCP session duration is based on a timeout configuration, and a separate timeout parameter is available for FCC and RET under config>mcast-mgmt>mcast-info-policy>video-policy>video-interface, namely the fcc-session-timeout and ret-session-timeout parameters. As the FCC RTCP session timeout is generally shorter than the RET session timeout, the recommendation is to configure the FCC RTCP session timeout to a lower timeout value, accounting for the time required to complete a fast channel change and complete the multicast handoff. This strategy frees up RTCP sessions for other subscribers and improves efficiency.
