In this talk, we analyze traffic data collected from deployed networks (a cellular wireless network used by public safety agencies, a satellite network used by Internet service providers, and the Internet). We also describe the current projectdealing with traffic collection from BCNet, the Vancouver Lower Mainland Gigabit Ethernet network. We describe collection of traffic data and employ statistical analysis to characterize traffic loads and distribution of applications and packet sizes in a hybrid satellite-terrestrial system. We investigate long-range dependence as the traffic patterns vary during a day, propose a traffic model on the Transmission Control Protocol (TCP) connection level, and use data from billing records to predict traffic using autoregressive integrated moving average model and evaluate its performance. Data collected from BCNet will be used to analyze behavior and performance of the Border Gateway Protocol (BGP) with a goal to design better routing algorithms. Biografia Resumida Ljiljana Trajkovic´ (S'78-M'86-SM'95) received the Dipl.Ing. degree in her native Yugoslavia in 1974, the M.Sc. degrees in electrical engineering and computer engineering from Syracuse University, Syracuse, NY, in 1979 and 1981, respectively, and the Ph.D. degree in electrical engineering from University of California, Los Angeles, in 1986. She is currently a Professor in the School of Engineering Science at Simon Fraser University, Burnaby, BC, Canada. From 1995 to 1997, she was an NSF Visiting Professor in the Electrical Engineering and Computer Sciences Department at University of California, Berkeley. She was a Research Scientist at Bell Communications Research, Morristown, NJ, from 1990 to 1997, and a Member of Technical Staff at AT&T Bell Laboratories, Murray Hill, NJ, from 1988 to 1990. Her research interests include high-performance communication networks, intelligent control of communication systems, computer-aided circuit analysis and design, and theory of nonlinear circuits and dynamical systems. She is Technical Program Co-Chair of ISCAS 2005. She served as Technical Program Chair and Vice General Co-Chair of ISCAS 2004. Dr. Trajkovic is currently serving on the Board of Governors of the IEEE Circuits and Systems Society and the IEEE Systems, Man, and Cybernetics Society. She is an Associate Editor of the IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS (PART I). She was an Associate Editor of the IEEE TRANSACTIONSONCIRCUITSAND SYSTEMS (PART II) from 2001 to 2003, the IEEE CIRCUITS AND SYSTEMSMAGAZINE from 2001 to 2003, and the IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS (PART I) from 1993 to 1995. She was Chair of the IEEE Technical Committee on Nonlinear Circuits and Systems in 1998. She is currently Chair of the IEEE Circuits and Systems Society joint Chapter of the Vancouver/Victoria Sections.
