Abstract:
Embodiments of the invention can resolve conflicts between candidate master network devices such as may be encountered in a failover condition. In a common type of failover protocol, two or more candidate master devices send messages to each other prior to a failover condition. A witness device (or process or service) also casts a vote to prevent a stalemate condition between the two candidate master devices that could lead to an error condition where multiple masters, or no masters, are elected.
