Abstract
A system and method are provided for controlling mastership among multiple devices in a fault tolerant manner. The devices may be configured to transmit and receive redundant heartbeat signals to indicate the mastership state of the device. The signals may operate in a plurality of configurations including active-master, ready and not-ready. By detecting the signal configuration sent from the other devices, each device is capable of managing its own transitions into and out of mastership in order to ensure that there is one and only one device functioning as master.
