Adaptative heartbeat flow for cluster node aliveness detection

摘要

One embodiment of the present invention provides a computer system comprising a first node, adapted to be connected via at least a link to a second node. The first node includes a receiving component capable of receiving repetitively a presence message comprising an indication of a current delay for a status detection of the second node, a handling component capable of determining the status of the second node from a delay derived from received delays, and from the time succession of receipt of said presence messages.
