Patent ID: 8817597

Claim:
A network comprising: a first plurality of links; a second plurality of links and a plurality of nodes, each node communicatively coupled to two neighbor nodes using the first plurality of links and to two skip nodes using the second plurality of links; wherein, three neighboring nodes of the plurality of nodes form a triple modular redundant (TMR) set having a first end node, a second end node, and a center node, the first end node configured to transmit output data in a first direction and the second end node configured to transmit output data in a second direction; and wherein the plurality of nodes further comprises a first guardian node adjacent the first end node and a second guardian node adjacent the second end node, wherein each of the first and second guardian nodes is configured to forward only data received from its respective adjacent end node, wherein each of the first and second guardian nodes is further configured to indicate integrity of the forwarded data based on a comparison of data received from its respective adjacent end node and the center node; wherein the nodes of the plurality of nodes that form the TMR set, the first guardian node, and the second guardian node are determined according to a schedule; wherein the plurality of nodes are configured to shift the TMR set such that a faulty node in the TMR set is replaced by another node of the plurality of nodes.
