Abstract
The original mode becomes hard to meet the requirement of power communication resource management for the network environment with complex topology structure, with multi-vendor resource in it. Since management of power communication resource is faced with a variety of challenges, it is very meaningful to set up a suitable topology for the connection of power communication resource and visualize this topology in an optimized way. This paper firstly analyzes several classic layout algorithms for topology visualization and makes a comparison among these algorithms, and then selects a modified tree layout algorithm based on a spanning tree frame to visualize the network topology according to the characteristics of power communication resource management's network topology.
