<p>PURPOSE:To attain routing in response flexibly to a status change in a network by utilizing a unidierectional information transmission function so as to add outputs of a threshold element in other node on a local area network. CONSTITUTION:When a status notice packet reaches its own node 21, a difference between a content of a data area corresponding to its own node and a content at circulation of a preceding packet is taken and the sum of inputs from a threshold element 22 of other node to each threshold element 22 is obtained. Then each threshold element 22 applies sum of weighting to the input sum, outputs of other threshold element 22 in its own node and of itself and an input from a network status input means 20 before the output, applies threshold level processing to the result to output 0 or 1. The output is added to a relevant area of the status notice packet and sent. Nodes constituting a LAN repeat the operation at each arrival of the status notice packet and as a result, a packet is outputted in a direction of a link corresponding to the threshold element 22 whose output is 1 in the equilibrium of the control network 23.</p> |
