Title:

 "Towards Terabit Ethernet-Based Optical Networking"

Abstract:

 The beginning of the second decade of the 21st century has been characterized by a paradigm shift in the overall meaning of the term “information society.” First, “on-demand” communication and information exchanged at a variety of speeds, connection qualities, and underlying content has become vital. Since the Internet has become synonymous with the information era, significant efforts have been invested in making it flexible, universally accessible and affordable. Secondly, by 2015, IP traffic in the United States alone will reach an annual total of 1,000 exabytes, which is 50 times larger than the corresponding 2008 value. In response to this trend, rapid transition to a unified, high-speed packet-based core/edge network architecture, which extends all the way from data centers to both residential and business end-users, is being undertaken by major telecom carriers all around the globe. The current network must thus evolve into a dual-layer terabit Ethernet architecture that enables flexible data packet transport over fixed, high-speed optical bandwidth pipes. The fundamental question is thus how to reconcile the competing flexibility versus speed requirements, and provide sufficient on-demand bandwidth to each user, while also satisfying quality of service challenges and energy constraints. In this presentation, the key technologies, and practical considerations for realizing the next-generation terabit Ethernet based optical network will be discussed, along with a survey of state-of-the-art research activities and promising future directions in this area.

Bio:

Milorad Cvijetic received his Ph.D. in Electrical Engineering in 1984 from the University of Belgrade in Serbia. After joining the University of Arizona College of Optical Sciences as a professor in August 2011, he established the Advanced Optical Networking Research Lab and began teaching optical communications and networking courses at both the undergraduate and graduate levels. Prior to joining the University of Arizona, he served as vice president and chief technology strategist at NEC Corporation of America in Herndon, Va. In his more than 30 years in optical communications and networking, he has participated in numerous hero experiments in some of the world’s leading industry labs (Nortel, NEC), emerged as one of the pioneers of coherent optical detection systems, and become a technical leader responsible for the introduction of the first terabit DWDM system in the largest global telecom network.


Cvijetic has published over 100 technical papers, has solely authored three books and authored or coauthored 12 US patents, all related to optical communications and networking. He has participated in numerous technical conferences and symposiumsin the roles of conference chairman, technical committee member, short course instructor and invited speaker. His current research interests include high-speed DWDM optical transmission systems with advanced modulation formats and detection schemes, multilayer high-capacity optical networks, high-speed OFDM/MIMO networking and converged optical-wireless systems.
