Περίληψη ομιλίας:
High-speed packet switches achieve increasingly higher throughputs and
better jitter management at
the expense, however, of substantial increase in utilized power. The latter
has become an acute
problem, as higher power results in unacceptable thermal stress of switching
chips/systems and
requires extensive cooling apparatus. Low power circuit design is one way to
partially address the
problem. Instead, in this talk we focus on operational and algorithmic
methods for power managing
switches.
We present some recent results for power-aware packet scheduling in packet
switches. We focus on
the power vs. latency tradeoff and discuss how to systematically manage
power/speed modes against
acceptable packet delays and traffic bursts. The power management algorithms
are also aligned with
the need to achieve maximal throughput when the traffic load becomes
excessive.

Nick Bambos is a Professor at Stanford University, having a joint
appointment in the Department of
Electrical Engineering and the Department of Management Science &
Engineering. He heads the
Network Architecture and Performance Engineering research group at Stanford,
conducting research
in wireless network architectures, the Internet infrastructure, packet
switching, network management
and information service engineering, engaged in various projects of his
Network Architecture
Laboratory (NetLab). He is now heading a new research initiative at Stanford
on Networked
Information Service Engineering.
He received his Ph.D. in Electrical Engineering and Computer Sciences (EECS)
from the University
of California at Berkeley (1989), as well as the M.S. in EECS (1987) and the
M.A. in Mathematics
(1989) from the same University. He graduated in Electrical Engineering from
the National
Technical University of Athens-Greece (1984) with first class honors. Before
joining Stanford as an
Associate Professor in 1996, he served as Assistant (1990-95) and tenured
Associate Professor
(1995-96) in the Electrical Engineering Department of the University of
California at Los Angeles
(UCLA).
Nick Bambos has held the Cisco Systems Faculty Development Chair (1999-2003)
in computer
networking at Stanford and has won the IBM Faculty Award (2002) for
high-impact research in
performance engineering of computer systems and networks. He has received
various awards,
including the NSF young investigator award, the Cisco Systems Chair at
Stanford, the IBM faculty
award, etc. He has also been a U.C. Regents Fellow, a David Gale Fellow, and
an Earl Anthony
Fellow.
