Abstract: | The bandwidth of a wavelength channel in WDM optical networks is very high compared to the user’s requirements for various
applications. Therefore, there is a scope for better utilization of channel bandwidth by traffic grooming, in which several
user’s channels are multiplexed for transmission over a single channel. Several research works have been reported on traffic
grooming routing and wavelength assignment (GRWA) for static and dynamic traffic pattern under centralized environment. Distributed
dynamic grooming routing and wavelength assignment (DDGRWA) is a new and quite unexplored area in WDM optical mesh networks.
This article introduces the concept of distributed traffic grooming in WDM mesh networks which also includes virtual topology
construction, reconfiguration, routing and wavelength assignment in the distributed environment assuming incoming traffic
to be dynamic in nature. We have also presented simulation results of our algorithm on dynamically generated traffic under
various network topologies. |
