In this paper, we propose a fault tolerant network architecture called Hierarchical Scalable Fault-tolerant Ethernet (H-SAFE) for mission critical systems. The proposed architecture is a tree based structure which provides multiple paths to route a packet. If any failure occurs in current path, then the alternative path recovers the failure and reroute the packet to destination without any information loss. In the failure state of any route, the fault detection and rerouting can be done within 750ms, which is a reasonable time for fault tolerance.
