Snow Crystal Method for Visualizing Hierarchical Large-Scale Telecommunication Networks (Special Issue on Network Operations and Management)

概要

This paper proposes the Snow Crystal method, which aims to present the hierarchies of a large-scale telecommunication network on one screen. This will improve the user interface of a network operation system for network operations and management. With the proposed presentation method, locations of nodes are automatically set based on the number of hierarchy levels and the number of nodes. The nodes in the same hierarchy level are located on the same circle at even intervals. The center of the circle that corresponds to the top hierarchy level is set at the center of the screen. The radius of the circle is determined by the number of nodes. The centers of circles that correspond to the second hierarchy levels belonging to the nodes of the top hierarchy level, are located on a larger circle with the same center point as the top level circle at even intervals. The centers of circles that correspond to the third hierarchy levels are located at even intervals on a circle with the same center point as the second level circle, which the third levels belong to. The nodes of the subsequent levels are located in the same way. The proposed presentation method is successfully applied to a large-scale telecommunication network. Moreover, the results of an operating experiment with the proposed method show its effectiveness for presenting hierarchies of large-scale telecommunication networks.
