Abstract:
A method, system, and computer program for managing network connectivity between a plurality of nodes and a network resource. The network resource includes a primary path to the nodes and at least one redundant path. A detecting module is configured to determine if the primary path is unavailable to at least one affected node belonging to the plurality of nodes. A switching module is configured to presumptively switch the affected node to the redundant path if the primary path is unavailable. An initiating module configured to initiate a voting procedure among the plurality of nodes to select a new path to the network resource, wherein data flow at the affected node through the redundant path continues during the voting procedure.
