| Summary: | A wavelength channel offers a much larger bandwidth than multicast applications require.
In order to improve the efficiency, wavelength division multiplexing (WDM) technology
can be used for multicast applications with large transmitting capacity. This final year
project aims to develop a proper traffic grooming methods and gain a better
understanding on the working theories of the WDM technology. We launch a new
grooming scheme with leakage control. Light trees with acceptable percentage of
wastage will be chosen for the grooming. The method of building new light trees will be
based on the idea of tree splitting. Computer simulations are used to evaluate the
performance of this scheme. Through the analysis, we conclude that introducing leaking
into the grooming scheme improves the efficiency of the resource utilization. The
relationship between blocking probability and the add-and-drop ratio is also investigated
in this report. With a proper add-and-drop ratio, the performance of this scheme can be
optimized. We suggest that the programming should be further improved and different
network topologies can be used in the future study. |
