COLLECTOR DEVICE, NETWORK MANAGEMENT SYSTEM AND NETWORK MANAGEMENT METHOD

摘要

PROBLEM TO BE SOLVED: To integrate host-by-host traffic data under a plurality of protocols, in a network environment performing communication using a plurality of addresses with a plurality of protocols.;SOLUTION: A collector device collects and stores traffic data measured in a network in which a plurality of nodes are connected. In an address management table 321, a first address of a first protocol allocated to a node etc. in the network is associated with an identifier of a physical or logical device, and also a second address of a second protocol is associated with the identifier. On receiving a traffic data, an ID converter 602 identifies protocol information of the traffic data. When the traffic data is related to the first protocol, it converts the first address into the corresponding identifier; whereas when the traffic data is related to the second protocol, it converts the second address into the corresponding identifier. The traffic data is aggregated and analyzed according to the identifier.;COPYRIGHT: (C)2012,JPO&INPIT
