Abstract: A computing device may be joined to a cluster by discovering the device, determining whether the device is eligible to join the cluster, configuring the device, and assigning the device a cluster role. A device may be assigned to act as a cluster master, backup master, active device, standby device, or another role. The cluster master may be configured to assign tasks, such as network flow processing to the cluster devices. The cluster master and backup master may maintain global, run-time synchronization data pertaining to each of the network flows, shared resources, cluster configuration, and the like. The devices within the cluster may monitor one another. Monitoring may include transmitting status messages comprising indicators of device health to the other devices in the cluster. In the event a device satisfies failover conditions, a failover operation to replace the device with another standby device, may be performed.

Abstract translation: 计算设备可以通过发现设备，确定设备是否有资格加入集群，配置设备以及为设备分配集群角色而与集群相连。 可以将设备分配为集群主控，备份主控，主动设备，备用设备或其他角色。 集群主机可以被配置为向集群设备分配诸如网络流处理的任务。 集群主备份主机可以维护与每个网络流，共享资源，集群配置等相关的全局运行时同步数据。 群集中的设备可能会相互监视。 监视可以包括将包括设备运行状况的指示符的状态消息发送到集群中的其他设备。 在设备满足故障切换条件的情况下，可以执行将设备替换为另一备用设备的故障转移操作。
