Patent ID: 10140192

Abstract:
An apparatus includes nodes each configured to relay data between the nodes. When a failure occurs in a first-node, a management-node determines, based on power consumption and/or memory usage of the nodes, a collection-node that transmits an instruction in first direction approaching the first-node and a second direction approaching a storage-node, respectively. A second-node that is neither an adjacent-node adjacent to the first-node nor the storage-node, upon receiving data including the instruction, transmit data obtained by adding an evaluation value for the second-node to the received data, in the first or second direction. Each of the adjacent-node and the storage-node, upon receiving data including the instruction, transmit data including an evaluation value for another node included in the received data and an evaluation value for the each node, to the collection-node which determines transmission routes between the collection-node and the first-node, and between the collection-node and the storage-node.
