Patent ID: 7206289

Claim:
A method of managing traffic by determining numbers of packets transferred via a site in a telecommunications network including routers and network segments interconnected to the routers for transferring packets over the network, comprising the steps of: holding routing tables including an indication of a next router to which a packet is to be transmitted next and Use columns associated with the routing tables at the routers; collecting the routing tables and the Use columns from the routers and storing the routing tables and the Use columns collected in connection with the routers; storing information on connections between subject ones of the routers to be managed and connections between the subject routers and subject ones of the network segments to be managed in a topology database; rearranging the Use columns collected with respect to a destination network segment of the network segments, and indexing the routers to which the Use columns belong to form a calculation table for calculating a number of first packets sent together with the indication of next routers associated with the Use columns; preparing a model of router-to-network traffic distribution matrix based on the topology database; determining, based on the indication of next routers listed on the calculation table, whether or not the subject router has relayed a packet sent from preceding one of the routers which is upstream the subject router; using, if the subject router has not relayed a packet, a value in the Use column of the subject router as a number of second packets sent between the subject router and the destination network segment, or subtracting, if the subject router has relayed a packet, a value in the Use column of the preceding router from a value in the Use column of the subject router to use a resultant value as the number of packets; and modifying the model of router-to-network traffic distribution matrix with the number of the second packets calculated to form a first router-to-network traffic distribution matrix; and managing traffic with the model of router-to-network traffic distribution matrix at a traffic distribution manager.
