Clock manager redundancy for time synchronized networks

Abstract

An apparatus for clock manager redundancy comprises a clock circuitry to manage a clock for a device; a first processing circuitry coupled to the clock circuitry to execute instructions to perform operations for a clock manager, the clock manager to receive messages with time information for a network and generate clock manager control information to adjust the clock to a network time for the network; a hardened execution environment coupled to the clock circuitry and the first processing circuitry, the hardened execution environment to comprise: a detector to monitor the clock manager and generate an alert when the detector identifies abnormal behavior of the clock manager; and a second processing circuitry to execute instructions to perform operations for a redundant clock manager, the redundant clock manager to take over operations for the clock manager in response to the alert from the detector. Other embodiments are described and claimed.
