This work contributes to the research area of ForCES. The framework based on Web, including collecting data, transmitting data and drawing graph, is set using the Applet/Servlet frame according to J2EE. In particularly, we present a new arithmetic which can be integrated into the Sugiyama algorithm for drawing hierachical graphs. We propose applying this technique after decreasing the number of so-called dummy nodes in a layered directed cyclic graph and displaying graceful LFBs topology layout. Finally, a series of experimental results and some important conclusions are given.
