    摘要： A gossiping scheme for sharing node status in a cluster of nodes provides a robust mechanism for determining node status within the cluster. Nodes transmit gossip messages to each other nodes, the gossip messages listing other nodes in the cluster that are operational. When a node does not receive a gossip message from a particular node within a predetermined time period, then the node transmits messages to the other nodes indicating that the particular node is down. However, if another node has received a packet from the particular node within the predetermined time period and receives the node down message, then the other node responds with a node alive message.

    摘要： An event notification method for distributed processing systems provides reduction of queue space and event processing bandwidth associated with duplicate events such as a particular event that is duplicated and results in multiple event notifications propagated for multiple consumers. When a duplicate event notification is received at an input to an event notification queue, rather than queuing the duplicate event notification, a sequence number of the event notification already in the queue is updated to indicate to the event consumer, exactly how many duplicate events have been received. The timestamp of the updated event notification may also be set to the timestamp of the most recently received duplicate event notification.

    摘要： A second node receives a message from a first node in a cluster environment. The message includes a unique identifier of a shared data storage device including a cluster configuration database that defines membership of nodes in a cluster. In response to receiving the message, the second node attempts to find the shared data storage device. In response to finding the shared data storage device, the second node locates and reads the cluster configuration database on the shared data storage device. The second node then assimilates a cluster configuration update indicated by the cluster configuration database.

    摘要： Communication between clusters of processing nodes is initiated by designating a link layer address and a target node name in a remote cluster. The link layer address is transmitted to the target node via a regular network transmission. The link layer address is stored locally in each cluster and the nodes in each cluster are signaled that a configuration change has been made, so that gateway nodes in the clusters can obtain the link layer address to use for subsequent communications with the other cluster, such as event notifications of node status changes.

    摘要： Communication ability between nodes in a cluster-based computer system is tracked to inform applications executing on the nodes of the existence and quality of the endpoint-to-endpoint communications available between the nodes. Communications between a node and other nodes are tracked, and a database records the communication ability between the node and the other nodes for each link between the nodes. The tracking and recording are repeated at the other nodes. A registration by an application executing at a particular one of the nodes to receive notifications of changes in the communication ability with another node over a particular link (or in general) will cause notification of the application when the link status changes.
