PROJECT
OUTLINE
This research project is to investigate
the performance of a number of different dynamic routing and wavelength
assignment (RWA) strategies for survivable wavelength-routed optical
networks (WRONs). It includes how to establish a lightpath (i.e. end-to-end
all-optical connection) between two nodes in a network. It is implemented
using language C. The objective is to minimize the amount of resources
needed for each lightpath. The routing strategies will take into account
the availability of channels on a fiber, the number of transmitters,
receivers per node, and length of the proposed path. In addition, it
includes consideration of how to maximize "sharing" of resources
for backup paths, which usually remain idle under normal fault-free
conditions.
Through this project, I will learn the fundamental concepts
of optical networks, related development and research directions. Then
I will implement and test the optimal integer linear programming (ILP)
formulation using CPLEX.
Finally, I will develop and test heuristics for RWA in optical network
and compare the performance with the optimal solutions.
This project has the close relation with the previous
projects (see related projects) that
I had worked under Dr.
Jaekel's supervision before.
