Patent ID: 8582446

Claim:
A method for responding to changes in a data communication network system comprising a plurality of routers, said routers of the plurality of routers being electrically connected together in a network tree structure, each router of the plurality of routers comprising an electronic connection port and a routing table, a direct current balance existing at the electronic connection port of each router of the plurality of routers, said method comprising: electrically connecting together the routers of the plurality of routers in the network tree structure via original electrical connections among the routers; each router of the plurality of routers generating and storing the routing table respectively in each router; after said electrically connecting together the routers in the network tree structure via original electrical connections among the routers, adding new electrical connections among the routers of the plurality of routers via positive and negative signal lines and ground lines at the respective electronic connection port of each router of the plurality of routers for subsequent use of said positive and negative signal lines to calculate a direct current (DC) voltage difference between the positive and negative signal lines of the electronic connection port of each router of the plurality of routers, said new electrical connections among the routers configured to transmit electrical signals among the routers of the plurality of routers; after said adding said new electrical connections, calculating the DC voltage difference between the positive and negative signal lines of the electronic connection port of each router of the plurality of routers; after said calculating the DC voltage difference, determining that the calculated DC voltage difference is outside of a predetermined parameter range of distinct voltages; determining, from said determining that the calculated DC voltage difference is outside of said predetermined parameter range of distinct voltages, that a change has been detected in the direct current balance at the electronic connection port of at least one router of the plurality of routers; ascertaining, from said determining that said change has been detected in the direct current balance at the electronic connection port of at least one router of the plurality of routers, that changes in the data communication network system that relate to each router of the at least one router have occurred; and responsive to said ascertaining, each router of the at least one router regenerating a new routing table respectively for each router of the at least one router, said new routing table for each router of the at least one router comprising the changes in the data communication network system that relate to each router of the at least one router.
