摘要

PROBLEM TO BE SOLVED: To specify a link having a high possibility of the occurrence of congestion when a plurality of IP links become uncommunicable.;SOLUTION: A congestion influence degree evaluation apparatus 10 uses network setting information and fault position information indicative of a fault pattern to create route information 134 indicative of a detour route in the case that a fault of the fault pattern occurs on a network. Next, based on the detour route and alternating traffic information in the network, the traffic volume information 135 of each link in the network is obtained for each fault pattern. The presence/absence of a congestion occurrence link from a result of simulation and a degree of congestion are outputted as a congestion influence degree evaluation result when there is the congestion occurrence link.;COPYRIGHT: (C)2010,JPO&INPIT
