Autonomous fault detection and recovery system in large-scale networks

In networks like Combat ship data network, the Ethernet is required to provide fault tolerance to all of its constituents for smooth operations. The analysis in this paper is done on the basis of our already proposed scheme Recursive Scalable Autonomous Fault tolerant Ethernet. Where, the large-scale network is divided into small subnets by limiting the number of nodes in each. The nodes in RSAFE contain two Network Interface Cards for dual connectivity in network. The results show that failure can be detected by missing of 2 consecutive Heartbeat Messages, which is acceptable performance in a network, along with failover, RSFAE is also cost effective solution, it is capable to even extend itself without interrupting the existing structure.
