Network verification device, network verification method and program recording medium

A network verification method, comprising:

• acquiring physical path information relating to a pair of physical devices serving as endpoints of a physical path by which a communication packet is transmitted and received in a network to be verified;
• calculating, based on configuration information of virtual devices in a virtual network that, by being associated with the network, is virtually set so as to transmit a communication packet using the network, a pair of the virtual devices serving as endpoints of a virtual path set so as to transmit and receive the communication packet in the virtual network;
• and
• detecting a setting violation in the network, based on the acquired physical path information and the calculated pair of the virtual devices.

A storage medium storing a program that causes a computer to execute:

• a process that acquires physical path information relating to a pair of physical devices serving as endpoints of a physical path by which a communication packet is transmitted and received in a network to be verified;
• a process that calculates, based on configuration information of virtual devices in a virtual network that, by being associated with the network, is virtually set so as to transmit a communication packet using the network, a pair of the virtual devices serving as endpoints of a virtual path set so as to transmit and receive the communication packet in the virtual network;
• and
• a process that detects a setting violation in the network, based on the acquired physical path information and the calculated pair of the virtual devices.
