ABSTRACT:
Methods and systems are directed to managing a protocol network failure in a network clustering system. A cluster master and each client member in the cluster are configured to determine a primary protocol network, a secondary protocol network, and the like, for exchanging a cluster protocol message. Each client member in the cluster determines its ‘active protocol network’ from at least the primary protocol network, and the secondary protocol network when it joins the cluster. Each client member tests its connectivity to the cluster master through the primary protocol network. If a client member detects a failure on the primary protocol network, it dynamically fails over to the secondary protocol network, or the like, without leaving the cluster. If connectivity to the primary protocol network is restored, the client member dynamically resumes the protocol message exchange on the primary protocol network without leaving the cluster.
