Redundant Path Reconfiguration for Fail-Safe Industrial Data Transmission

The patent creates a copy of the data stream through parallel redundant paths without adding complex sequence numbers or filtering mechanisms. The simple duplication approach maintains reliability while avoiding the protocol complexity of HSR/PRP by using identical copies rather than numbered sequences that require synchronization and filtering.

The patent segments the data transmission into parallel independent paths without requiring complex coordination between them. Each path operates independently with simple duplication, avoiding the need for sequence number management and duplicate filtering that characterizes HSR/PRP implementations.

The patent pre-establishes multiple diverse redundant paths before any failure or change occurs. By having multiple pre-calculated paths that are diverse in their routing, the system can immediately switch to an alternative path if one becomes affected, preventing the simultaneous failure scenario that occurs with GADAG-based single path calculation.

The patent prepares multiple backup paths in advance as a cushion against potential failures. This beforehand preparation ensures that if one path is affected by GADAG changes or other issues, alternative paths are already available and can be activated immediately, maintaining communication continuity.

The patent implements dynamic path selection where multiple redundant paths are monitored and the system can adaptively switch between them based on current network conditions. This dynamic approach allows the network to handle topology changes gracefully by activating alternative paths when needed, maintaining communication stability during adaptations.

The patent prepares multiple alternative paths in advance as cushions against topology changes. When network expansions or repairs occur, these pre-established alternative paths provide a safety buffer that prevents communication failures, allowing the network to adapt while maintaining reliability.
