A monitoring device (10) sets a first node (20A) that is a node on a transmission side that switches a route of a packet in user communication to copy the packet in the user communication, enable an INT setting, and transmit the copied packet to each of routes that are switching destination candidates based on an instruction input from a maintenance person. In addition, the monitoring device (10) sets a second node (20B) that is a node on a reception side that accommodates the routes that are switching destination candidates to collect INT information of the copied packet and discard the copied packet. Thereafter, the monitoring device (10) acquires the INT information of the copied packet from the second node (20B) and visualizes communication quality of each of the routes that are the switching destination candidates in the user communication based on the acquired INT information.
