abstract = {Recent advances in wavelength-division
multiplexing (WDM) technology will provide bandwidth intensive multicast
applications with large transmit capacities. This article provides two new
grooming schemes that lead to efficient resource utilization in WDM networks.
They are called Light-Tree Division-Destination Branch Node-based Grooming
scheme (LTD-DBNG) and Light-Tree Division-Adjacent Node Component-based Grooming
scheme (LTD-ANCG). These schemes are based on the idea of dividing a light-tree
into smaller sub-light-trees. They improve the efficiency of resource
utilization and also lower the optical-electronic-optical conversion overhead.
We use computer simulations to evaluate the performance of these schemes. Our
simulations demonstrate that compared with existing algorithms, these schemes
significantly reduce the request blocking probability (BP) but can be
implemented with very reasonable electronic processing, with LTD-ANCG performing
better than LTD-DBNG but with greater complexity. We also evaluate the BP of
these schemes considering variations in the add/drop ratio and demonstrate that
a proper choice of this ratio will provide target BP with low network costs.}
