SCREEN DISPLAY DEVICE, SYSTEM, AND SCREEN GENERATION METHOD

摘要

A screen display device (200) displays a three-dimensional display screen on which network (NW) devices, links, paths, obstruction points (alarms) are displayed on a map representation. The screen display device (200) defines rungs on the basis of attributes of the devices so that a device of a lower rung (a terminal device in the NW) is placed at a lower position while a device of a higher rung is placed at a higher position on the three-dimensional display screen. Further, for an area where devices are on multiple rungs, the screen display device (200) displays a mark at the area to make the rung height of each device more recognizable. Also, the screen display device (200) provides an indication enclosing devices that form an active system/backup system pair to make it easy to understand whether there is a system that remains normal so that service can be offered.
