Abstract: A fault router method and system for use in a parallel redundant network environment provide additional safeguards over traditional redundant networks. Where multiple connection faults on multiple machines would ordinarily stifle communications between two or more network entities, the fault router passes packets between redundant networks to bypass connection faults. Compatibility and timing improvements allow for the extension of the parallel network environment, and provide for time-synchronized network operation.

Abstract: A method of fault detection and recovery utilizes dual independent networks to provide fault-tolerance. These networks, a primary and alternate network, are utilized such that communications for a particular computer take place via that computer's preferred network by default. Faults are detected through the use of a heartbeat pinging mechanism to detect faults on the network itself and by periodic port integrity checks to detect port faults. The integrity of the non-default network and port are also periodically verified to assure effective fault recovery. Upon detection of a fault, a packet routing table in the detecting computer is altered to set the detecting computer's default network to the previously non-default network. Additionally, a new gateway packet is transmitted which allows other network computers to modify their routing tables to communicate with the detecting computer over its current default network.
