— As wavelength-division multiplexing (WDM) evolves towards practical applications in optical transport networks, waveband switching (WBS) has been introduced to cut down the ope...
— In this paper, we study the Routing and Wavelength Assignment (RWA) problem in a semi-dynamic scenario where rearrangements are conducted in a series of sessions after traffic...

—For a large-scale mesh network with dynamic traffic, maintaining the global state information in a centralized fashion is impractical. Hence, distributed schemes are needed to ...
Routing and wavelength assignment (RWA) aims to assign the limited number of wavelengths in a wavelength-division multiplexed (WDM) optical network so as to achieve greater capacit...
In this paper, we address the issue of traffic grooming in arbitrary WDM mesh networks. We present a novel groomer architecture wherein a combination of grooming at two different ...
