Abstract:
Explosion of data and mass availability of Internet
connections around the globe had created huge bandwidth requirements
for bandwidth hungry applications. Despite the technological advances
in the core and their ability to transport, still much work has to be
done in the access networks in order to be able to let the broadband
traffic be transmitted transparently. Current solutions for access
networks do not provide a concrete solution for the famous last mile
problem. In this talk we will present optical access networks as viable
solutions to the ongoing problems in the access networks. Further we
will cover physical and technological limitations with the current
state-of-the-art optical technology. We will address the optical access
networks promises in responding to these shortcomings. We will focus on
passive optical networks (PONs), reviewing different type of PONs
considering their benefits and limitations. Ethernet passive optical
network (EPON) has been considered as an attractive solution to
next-generation broadband access networks due to its low cost and high
throughput. However, designing efficient bandwidth allocation
algorithms (DBAs) is a critical issue in EPON. In this talk, we will
also cover dynamic bandwidth allocation algorithms along with the role
which the multipoint control protocol (MPCP) plays in their design.
Bio:
Hussein Mouftah joined the School of Information Technology and
Engineering (SITE) of the University of Ottawa in 2002 as a Tier 1
Canada Research Chair Professor, where he became a University
Distinguished Professor in 2006. He has been with the ECE Dept. at
Queen's University (1979-2002), where he was prior to his departure a
Full Professor and the Department Associate Head. He has six years of
industrial experience mainly at Bell Northern Research of Ottawa (now
Nortel Networks). He served as Editor-in-Chief of the IEEE
Communications Magazine (1995-97) and IEEE ComSoc Director of Magazines
(1998-99). He is the author or coauthor of five books and more than 800
technical papers and 9 patents in this area of broadband packet
switching networks, optical and mobile wireless networks and quality of
service over the Internet. He is the joint holder of 5 Best Paper
and/or Outstanding Paper Awards. He has received numerous prestigious
awards, such as the 2007 RSC Thomas W. Eadie Medal, the 2006 IEEE
Canada McNaughton Gold Medal, the 2006 EIC Julian Smith Medal, the 2004
IEEE ComSoc Edwin Howard Armstrong Achievement Award, the 2004 George
S. Glinski Award for Excellence in Research of the U of O Faculty of
Engineering, the 1989 Engineering Medal for Research and Development of
the Association of Professional Engineers of Ontario (PEO), and the
Ontario Distinguished Researcher Award of the Ontario Innovation Trust.
Dr. Mouftah is a Fellow of the IEEE (1990), the Canadian Academy of
Engineering (2003) and the Engineering Institute of Canada (2005). |
