Optical Path Design Method considering Wavelength Utilization Efficiency and Wavelength Conversion in Multiple Network Configurations

Abstract (in Japanese) (See Japanese page) 
(in English) In the development of optical transmission networks, optical paths accommodated in each single network up to now are likely to be accommodated across multiple networks. In this case, optocal path design is executed in each network. Therefore, considering the wavelength continuity constraint, optical paths to be configured across networks may conflict with wavelengths in use between the networks. In order to decrease wavelength conflicts between networks, it is effective to use wavelength conversion and to route design in the optical path design. However, while the wavelength conversion easily improves wavelength utilization efficiency as it is used, the use of wavelength conversion requires equipment and power costs. In addition, in route design, wavelength resource consumption is large and wavelength utilization efficiency is lowered depending on the selected route. Therefore, when accommodating optical paths across multiple networks, it is necessary to design optical paths by considering wavelengths used in other networks and taking into account the use of wavelength conversion functions and route selection. In this paper, we propose a optical path design method that takes into account the utilization of wavelength conversion functions among multiple networks in order to accommodate optical paths with efficient wavelength utilization while utilizing appropriate wavelength conversion functions in a multi-network configuration. Specifically, the proposed method designs optical paths using a cost function that minimizes the use of wavelength conversion functions and load-balances the routes. The performance of the proposed method is evaluated by simulation, and it is shown that the proposed method can accommodate more optical paths than the conventional method.
