Abstract
An apparatus comprises a first processing device configured to manage, in a first mode of operation, one or more first tasks for a network switch, and to replicate, in the first mode of operation, state information for a network operating system of the network switch, the network operating system running on a second processing device in the first mode of operation. The first processing device is also configured to initiate, in response to one or more trigger conditions, an in-service switch-over from the first mode of operation to a second mode of operation. The first processing device is further configured to suspend, in the second mode of operation, at least one of the one or more first tasks, and to run, in the second mode of operation, at least a portion of the network operating system utilizing the replicated state information.
