Networking 2004: Tutorials
Tutorial Title: Automatically Switched Optical Networks (ASON) Instructor: Andrzej Jajszczyk Department of Telecommunications,  AGH University of Science and Technology Al.

Description of the tutorial: Growing competition between network operators, new characteristics of traffic as well as network survivability challenges trigger the need to migrate from SDH/SONET-based networks to a more flexible and dynamic optical infrastructure. The proposed tutorial will present current standards and concepts related to such an infrastructure and ways to implement it in real networks, along with challenges facing designers and system engineers. The tutorial presents migration from current networks towards Automatic Switched Optical Networks (ASON) that give the means to deliver end-to-end, managed bandwidth services efficiently, expediently and at reduced cost. Current status of optical networking is outlined and driving forces behind ASON are enumerated. Transport, control, and management planes of ASON are described, including such issues as: optical cross-connects, add-drop multiplexers, control plane models, and management of optical networks. Approaches to service resilience in optical networks using the ASON functionality are reviewed. The tutorial is concluded by presenting current standardization activities, open issues and perspectives of intelligent optical networking. Biography: Andrzej Jajszczykis a Professor at the AGH University of Science and Technology in Krakow, Poland. He received M.S., Ph.D., and Dr Hab. degrees from Poznan University of Technology in 1974, 1979 and 1986, respectively. He spent a year at the University of Adelaide in Australia, two years at Queen’s University in Kingston, Ontario, Canada, and half a year at École Nationale Supérieure des Télécommunications de Bretagne, France, as a visiting scientist. He is the author or co-author of six books and more than 170 scientific papers, as well as 19 patents in the areas of high-speed networking, telecommunications switching, and network management. He has been a consultant to industry, telecommunications operators, and government agencies in Poland, Australia, Canada, France, Germany, and the USA. He was the founding editor of the IEEE Global Communications Newsletter, editor of IEEE Transactions on Communications, and Editor-in-Chief of IEEE Communications Magazine. Starting from January 1, 2004, he is Director of Magazines for IEEE Communications Society. He has been involved in organization of numerous technical and scientific conferences. He is an IEEE Communications Society Distinguished Lecturer. He is a member of the Association of Polish Electrical Engineers and a Fellow Member of IEEE. He was a recipient of the Honorable Mention, IEEE Communications Society Best Tutorial Paper Award in 1995.
