摘要
The embodiments disclosed herein relate to using SNMP functionality for fast and accurate detection of node failure in a computer cluster. When cluster nodes are connected via a switch that provides SNMP capability, a trap mechanism can be used to immediately and proactively notify cluster nodes that a particular cluster node is disconnected from the network, potentially even before the remaining cluster nodes have noticed a lack of response. In addition, when a cluster node notices a lack of response from a particular cluster node, the switch can be queried for link status and traffic information that can be used for fast determination of node status.
