Abstract:This article aimed at the problem of insufficient in mesh and tree-like network topology reflects the level of the network, the on-off state of a single screen display, research based on polar coordinate algorithm for the center of radiation hierarchical topology graph realization method, realizes the automatic hierarchical topological graphics display and dynamic update, can achieve to describe a relation of the network equipment efficiently and clearly, the research results have been in multiple unit is a practice test, which provides important means for enhanced network management and maintenance.
