Computer Visualization of Optical Network Behavior
Faculty Mentor: Dr. Yung-Jui (Ray) Chen
Expected Graduation Date: May 2010
The goal is to design and code a visualization program to be utilized to study the optical network behavior under the Generalized Multi-protocol Label Switching (GMPLS) management model. The network will be empowered with the Wavelength Division Multiplexing (WDM) technology. The WDM technology allows a single fiber-optic connection between two nodes to carry multiple independent signal channels using different wavelengths. This allows the nodes to have a much greater capacity in communication. Furthermore each channel can be routed through intermediary nodes via its unique wavelength without electronic equipment intervention. This is called wavelength routing. The fiber optics network is a collection of edge nodes and core nodes connected by a fiber optic channel. The edge node collects data packets from users, groups them intelligently into wavelength channels and sends them through the network to reach destination users. The core nodes routes traffic through wavelength routing or regroups the incoming traffic from different sources and sends them out on new wavelength channels. The network research is to study and identify the proper management model and control parameters. The intention of the visualization program is to show how the traffics are arranged and are traveling through the network and to provide statistical display regarding the simulation at each edge and core node. The program shall be written in Java and will utilize two graphical packages, one is called Prefuse while the other is called Profusians.
