Fujitsu, a leading provider of business, information technology, and communications solutions, announced today that researchers from Fujitsu and The University of Texas at Dallas have been presented with the “Best Paper Award” at the 14th International Conference on Optical Networking Design and Modeling (ONDM 2010) for their joint paper on “Traffic Grooming and Regenerator Placement in Impairment-Aware Optical WDM Networks”. The annual award honors authors who present the highest quality paper at the conference.

In the award-winning paper the researchers examined the various capital costs associated with traditional approaches to overcoming signal degradation that results from common traffic grooming and signal regeneration in optical networks. The equipment modeling examples presented in the paper illustrate a variety of regenerator and electronic grooming scenarios, and resulting calculations confirm that optical network capital equipment costs can be significantly reduced when regenerator and electronic grooming functions occur together as compared to the placement of only regenerators or only electronic grooming.

The authors of the paper are Ankitkumar N. Patel, Chengyi Gao, and Jason P. Jue from the Erik Jonsson School of Engineering and Computer Science at The University of Texas at Dallas, and Xi Wang, Qiong Zhang, Paparao Palacharla, and Takao Naito from Fujitsu Laboratories of America.

“The breakthrough research by our scientists and graduate students from UT Dallas continues a long-standing tradition of Fujitsu collaborating with universities on cutting-edge communications projects,” said Hitoshi Matsumoto, president and CEO of Fujitsu Laboratories of America. “In this particular case I’m extremely pleased to see the authors recognized for the positive impact their discovery could have on the future of optical communications. Their work on this paper illustrates the type of industry-leading innovation our engineers incorporate into the optical networking products that our service provider and Enterprise customers deploy around the world.”

The ONDM conference, held January 31 through February 3 in Japan, focuses on cutting-edge, state-of-the-art research in optical networking. Organizers encouraged the submission of research papers relating the topics of optical networking to other areas and disciplines, such as the integration of optical and wireless networks or the role of optical networks for the future of Internet design.
