ABSTRACT:
Techniques are described of using votes of third-party components to select a master processor from a plurality of redundant processors. A master processor and a standby processor maintain communications with one another. If communication between the master processor and the standby processor fails, the processors may poll a set of registered voters to determine which of the processors is to be the master processor. In this way, the processors may determine which of the processors is to be master without the use of a shared indicator to specify which of the processors is to be the master processor.
