Fault-tolerant networking

Realizing network fault-tolerant method and device for providing network fault-tolerant manager detecting fault and including a node and an active channel corresponding node. The default detecting communication one or more method, a message to a link detection pulse. Which at a standby channel the failure recovery a cutting the data communication or cut to a fault node. Communication between nodes providing distributed detection, simultaneously detecting node for producing network fault-tolerant managers is inconsistent with the fault and fault-tolerant network managing machine to the node multi-point transmission breakdowns. The network fault-tolerant manager of the middle piece, is arranged above with each node the network physical layer which a logic level a network transmission layer. A method of qualify and by the circuit device in Ethernet AND/OR the commercial of purchase.
