Fault Tolerant Ethernet (FTE) is proprietary protocol created by Honeywell. [1][2]
Designed to provide rapid network redundancy, on top of spanning tree protocol.[3] Each node is connected twice to a single LAN through the dual network interface controllers. The driver and the FTE enabled components allow network communication to occur over an alternate path when the primary path fails.[4][5]
Default time before failure is detected, is Diagnostic Interval (1000ms) multiplier with Disjoin Multiplier (3), for a 3000ms recovery time.
Similar to Switch Fault Tolerance (SFT) in windows and mode=1 (active-backup) in Linux.
