A communication management system includes a display calculation unit configured to calculate, for each of a plurality of communication devices on a network, a display position of an icon that identifies the communication device in a display unit, based on positional information about the communication device. Further, the communication management system includes a complexity calculation unit configured to calculate complexity of a topology between a plurality of the icons, based on a display position of the plurality of icons. The display calculation unit corrects a display position of at least one of the icons when the complexity is equal to or more than a predetermined complexity threshold value.
