Abstract
A method, system, and architecture for detecting MCU failures is provided. The conference system detects the failure of MCUs that have been allocated to provide shared conference resources to conferences that are being hosted by the conference system. The conference system utilizes the sending and receiving of “heartbeat” messages between the MCUs and the conference server pool to detect failed MCUs. Upon detecting the failure of an MCU, the conference system performs a “rollover” of the conferences which were being serviced by the failed MCU to another available MCU. The conference system may then identify the clients which were connected to the failed MCU and notifies the clients that an MCU rollover has occurred and a new (replacement) MCU is available in order that these clients can reconnect and reestablish their media sessions.
