Abstract
The failure of a specific link of a specific node of a cluster is detected, for example through the operating system of the specific node. A notification of the failure of the specific link is disseminated to the nodes of the cluster, such that the nodes receive the notification prior to learning of the link-down event from the expiration of corresponding heartbeats, and process the event in parallel. The notification of the link failure can be disseminated by broadcasting a message notifying the nodes of the failure of the specific link. The notification of the link failure can also be disseminated by transmitting the notification to a centralized computing device which is polled by the nodes of the cluster at a specific frequency for notifications of link failures.
