<p><P>PROBLEM TO BE SOLVED: To solve the problem that, as network scale becomes larger, the number of nodes constituting a network and the number of connections of these nodes increase, a traffic stagnation spot is not always one and furthermore, even if stagnation in transfer is caused by the traffic stagnation at a certain place of a large-scaled network, it is difficult to specify a fundamental factor thereof. <P>SOLUTION: An individual status representing increase/decrease of traffics in the form of nodes that are network constitutive information and lines connecting these nodes is not presented, but traffics are aggregated on the management network unit basis such as for the unit of a LAN, for the unit of a VLAN, etc., and the traffic status is visualized so as to be easily grasped. The configuration of a management network is then hierarchized, network inside traffics are sorted from an input/output amount of each hierarchy, and balancing of input/output amounts by hierarchies is visualized. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
