SUMMARY OF QUALIFICATIONS

Dr. Konstantinos Kanonakis was born in Heraklion Crete, Greece, in 1982. He was awarded his PhD degree in the field of optical networks from the School of Electrical and Computer Engineering of the National Technical University of Athens (NTUA), Greece, in 2008 and the Dipl.-Ing. Degree from the same university in 2004. In March 2008 he joined the High-Speed Networks and Optical Communications group in AIT as a Post-Doc researcher. His main research interests are in the area of traffic engineering, design and analysis of architectures and control protocols for optical core and broadband access networks as well as their implementation in hardware. He has co-authored more than 20 papers that appeared in international peer-reviewed journals and conferences and serves as a reviewer for major journals (IEEE/OSA Journal of Lightwave Technology, Elsevier Computer Networks) and conferences.

RESEARCH/PROFESSIONAL EXPERIENCE

March 2008 – Present: Athens Information Technology, Athens, Greece:

Position: Post-Doc Researcher, member of the High-Speed Networks and Optical Communications Group.

Participates in the FP7 STREP project ICT-SARDANA, working on Architectural and MAC layer issues of next generation WDM-PON networks. He is also involved in the FP7 NoE projects BONE and EUROFOS.

January 2008 – March 2008: Forthnet S.A., Greece:

He worked for the demonstration application of the national project NGEAN. His involvement was in the programming of the embedded processors of a FPGA-based router.


September 2004 – January 2008: Telecommunication Systems Laboratory, National Technical University of Athens, Greece:

In the framework of the FP6 IP projects IST-MUSE I-II and IST-NOBEL I-II he was involved in the design, analysis and simulation of optical and broadband access networks.

In the framework of IST-MUSE I-II he performed extensive studies and simulations on broadband access networks. Part of his work was the investigation of scheduling mechanisms for the support of QoS at the access multiplexer. In addition, he was involved in the design of a generic scheduling component which can be configured to support various numbers of flows and used for building hierarchical schedulers in hardware using VHDL. The schedulers reside at the access multiplexer nodes, which aggregate traffic from access networks and forward it to the aggregation/metro networks over 10Gbps links. In October 2006 he cooperated with Alcatel-Lucent researchers for the successful integration of an instance of the design on FPGA at the company’s labs in Antwerp. Finally, he investigated ways of providing QoS at the access network to services lacking explicit signaling.

The work he has done for the projects IST-NOBEL I-II consists of studying novel optical core network architectures and protocols. More specifically, he was involved in the design of two different architectures and the respective control protocols for optical burst-switched networks. The first is based on clustering the system nodes, with different control protocols being used inside and outside the clusters, while the second makes use of slotted pipelined two-way reservations, achieving efficient and loss-less operation. The performance of both schemes has been evaluated using computer simulations, and it has been shown that they both outperform typical OBS approaches. Moreover, he developed analytical models for the evaluation of the aforementioned protocols, as well as for the performance of burst assembly mechanisms.

 

Summer 2003: University of Ljubljana, Slovenia:

As an exchange student he was involved in the research activities of the computer vision laboratory of the University of Ljubljana, Slovenia.

 

TEACHING EXPERIENCE

September 2004 – February 2008: Automation Engineering Department, Technological Institute of Piraeus, Greece:

He worked as a teaching assistant at the Automation Engineering Department of the Technological Institute of Piraeus, teaching the “Internet Protocols” course.
