Abstract

Systems and methods for visualizing traffic coming in from outside to a network to be managed and being sent out of the network. An information presentation apparatus acquires traffic information regarding a traffic specified in accordance with a user'"'"'s instruction, where the traffic information has been collected from one or more routers located at a border of the network to be managed. The apparatus also acquires path information regarding a path from a start router, through which the traffic passes into the network, to an end router, through which the traffic passes out of the network, referring to stored internal path information. The apparatus then informs a user of the acquired traffic information in association with the acquired path information. At least one of specification of the traffic and determination of the end router is performed referring to stored external path information.

and wherein

the specifying unit includes a unit that determines a destination network address corresponding to the end router, referring to the external information stored by the storing unit.

9. The apparatus according to claim 2, further comprising

a storing unit that stores internal information regarding internal paths of the network,

and wherein

the specifying unit includes a unit that determines an end router such that a router having an address designated by the user as the router'"'"'s connected address is the end router, referring to the internal information stored by the storing unit.

10. The apparatus according to claim 2, further comprising

a storing unit that stores internal information regarding internal paths of the network,

and wherein

the path acquiring unit acquires the path information regarding a path from the start router to the end router, referring to the internal information stored by the storing unit.

11. The apparatus according to claim 2, further comprising

an accepting unit that accepts designation of a start router from the user,

and wherein
