摘要： Users attempting to join a conference facilitated by an enhanced communication system employing a network communication protocol such as SIP and having a distributed architecture are enabled to request the conference through a numeric conference identifier. The conference directory identifier is assigned to an associated resource, rather than directly to a pool of resources in the communication system. If a pool is decommissioned, any conference directories with remaining data may be assigned to other pools, like users may be moved, to ensure continuity of the system.
摘要翻译：尝试加入会议的用户能够通过数字会议标识符来请求通过采用诸如SIP的网络通信协议并且具有分布式架构的增强型通信系统来促成会议。会议目录标识符被分配给相关联的资源，而不是直接地指向通信系统中的资源池。如果一个池已经停用，任何具有剩余数据的会议目录都可以被分配给其他池，如用户可能被移动，以确保系统的连续性。

摘要： A method, system, and architecture for providing a conference system that effectively achieves high availability conferencing is provided. The conference system architecture provides a conference system that comprises a set of stateless conference servers and a shared conference store to provide highly available conferencing to its users. The conference servers serve (host) conferences (meetings) that allow users to conduct distributed conferences. Each conference server generally performs conference provisioning operations and conference control operations. The shared conference store provides for the storage of conference state information, thus allowing the conference servers in the conference server pool to be stateless by maintaining conference state information on the shared conference store. A stateless conference server may also locally maintain, for example, in cache memory, some of the conference state information that is maintained on the shared conference store.

摘要： User defined routing rules are managed within a primary/backup architecture through continuous replication between home servers and their corresponding presence servers in an automatic manner. User set-up rules are stored and published by a designated presence server to home servers on which the user can register including the user's home registrar and any backup registrars. Changes to the rules may be disseminated and synchronized through comparison of versions and exchange of batches between the presence server and registrars.

摘要： 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.
摘要翻译：提供了一种用于检测MCU故障的方法，系统和体系结构。会议系统检测已分配给已由会议系统托管的会议提供共享会议资源的MCU的故障。会议系统利用发送和接收MCU与会议服务器池之间的“心跳”消息来检测故障MCU。在检测到MCU的故障时，会议系统会将故障MCU所服务的会议“翻转”到另一个可用的MCU。然后，会议系统可以识别连接到故障MCU的客户端，并通知客户MCU已经发生了翻转，并且新的（替换）MCU可用，以便这些客户端可以重新连接并重新建立其媒体会话。
