1. A network management apparatus comprising:
at least one memory configured to store program code; and
electronic circuitry including at least one processor, the at least one processor being configured to read and operate according to the program code, the electronic circuitry configured to:
acquire link information indicating a supportable communication rate for each of links among a plurality of nodes forming a network, wherein each link in the network is connected between at least two nodes from the plurality of nodes;
acquire traffic type information indicating a traffic type of traffic transmitted on at least one link among the plurality of nodes;
acquire statistical information indicating an amount of the traffic transmitted among the plurality of nodes including the at least one link; and
verify, in a case where it is assumed that a pseudo-failure has occurred on a first link among the plurality of the nodes, a risk of reconfiguring the network using a second link among the plurality of the nodes on which no pseudo-failure has occurred as an alternative link based on the link information, the traffic type information, and the statistical information
wherein the second link is different from the first link.
