The GRouter4 supports an optional redundant twin mode with enhanced reliability for high availability applications. Adept was the first to offer this feature in LON/IP routers. Adept’s implementation leverages years of experience and research. While in redundant twin mode two routers connect to the same LON channel but without duplicate forwarding of packets. This provides greater reliability without the scalability problems of excess duplicate packet traffic. The twins monitor, diagnose, and report faults. The secondary twin will automatically go active if the primary fails. Should there be a fault in either interface then both routers will go active and forward traffic until the fault has been healed. Standard Alarm SNVTs send out notification of faults. The router configuration is periodically and automatically synchronized between the two routers to reduce fail-over time and increase the fidelity between the backup and primary router operation.
