ABSTRACT:
The invention is directed to techniques for failsafe management of periodic communications between network devices. A first network device, for example, establishes with a second network device a first response interval by which the first device responds to a message received from the second device. Prior to commencing a software upgrade, the first device determines whether the event requires an interval of time during which the first device cannot respond to the message within the established first response interval. Based on the determination and prior to commencing the upgrade, the first device establishes with the second device a second response interval that equals or exceeds the first response interval. Upon completion of the event, the first device establishes with the second device a third response interval. The first network device therefore may automatically adjust response intervals to accommodate upgrades that may cause unnecessary thrashing.
