Predavanje: Prof. Admela Jukan, Next Steps towards IP-optical Service Convergence: A Network Management Perspective

Summary:

Despite the steady and significant increase in Internet traffic, today’s Internet topologies are stable, reliable, and - underutilized. This is mainly due to the proven ISP practice to overprovision IP links, - often up to seventy percent, thus allowing for accommodation of unpredictable flows, while keeping the network stable and resilient against attacks and failures. Even with major benefits, the practice of overprovision leads to high capital and operational expenses, as well as higher energy consumption. At first glance, dynamic optical circuits can address the downsides: optical circuits can be setup to bypass any congested or faulty IP links and are the “greenest technology”. However, the two networks – optical and Internet, have evolved as two fundamentally different and separately managed systems, and cannot easily operate in harmony. In this talk, I will discuss why past approaches to deploy dynamic optical circuits have not been widely adopted for IP routing, - from the point of view of network management, and present our research ideas on how Internet can effectively use optical bypass. I will talk about the importance of new systems research and present new directions in theoretical studies in this field, and also give a practical outlook from our EU Project ONE (www.ict-one.eu).

Bio:

Admela Jukan received her Dr. techn. degree (cum laude) in Electrical and Computer Engineering from the Technische Universität Wien, Austria and the M.Sc. degree in Computer Science from the Politecnico di Milano, Italy. She received her Dipl. -Ing. degree from the Faculty of Electrical Engineering and Computing (FER),  Zagreb, Croatia.

She is Chair Professor of Communication Networks in Electrical and Computer Engineering Department at the Technische Universität Braunschweig, Germany. Prior to coming to TU Braunschweig, she was research faculty at the Institut National de la Recherche Scientifique (INRS) Quebec, Canada, University of Illinois at Urbana Champaign (UIUC) and Georgia Tech (GaTech). In 1999 and 2000, she was a visiting scientist at Bell Labs, Holmdel, NJ. From 2002-2004, she served as Program Director in Computer and Networks System Research at the National Science Foundation (NSF) in Arlington, VA.  

Dr. Jukan serves as Associate Technical Editor for IEEE Communications Magazine and IEEE Network. She is a co-Editor in Chief of the Elsevier Journal on Optical Switching and Networking (OSN). She is an elected Vice Chair of the IEEE Optical Network Technical Committee, ONTC (Chair in 2014).  She currently coordinates a collaborative, large-scale EU project ONE, focusing on network management convergence of optical networks and the Internet. She is recipient of an Award of Excellence for the BMBF/CELTIC project “100Gb Ethernet” and was also awarded the IBM Innovation Award for applications of parallel computing and optical networking for rich digital media services.
