Abstract

A network control device includes a storage and a processor. The storage stores an identifying value and a severity value for each of network elements. The identifying values are hierarchized based on inclusion relationships between the network elements. The severity values respectively indicate a severity in sharing a risk of a failure in the network elements. When first and second paths are designated, the processor detects, for each of a plurality of target identifying values corresponding to a plurality of network elements implementing the first path, a longest matched identifying value having a longest region matching the target identifying value from among a plurality of identifying values corresponding to a plurality of network elements implementing the second path. The processor calculates a sum of severity values corresponding to the detected longest matched identifying values, and evaluates the second path for the first path based on the sum.
