Abstract:  Optical networks are different from conventional networks
from the security point of view for two main reasons: transparency -
this means that optical signals are routed through the network without
the network being aware of what information is carried by the signals,
and data rate - their high data rates imply that conventional security
measures may not be sufficient to keep up with the rate at which the
network can deliver data.  Furthermore, optical signal quality
monitoring is more difficult and not as extensive as electronic
monitoring.  Accordingly, physical security of the optical network must
be an important design consideration, and significantly enhanced
understanding of survivable optical network design is critical from all
layers' viewpoints.  

In this talk, two main research areas addressing the above issues will
be discussed: 
(a) monitoring and alarm management in optical networks for rapid
localization and isolation of fault and attack point, and (b)
provisioning network resources so that the network can adequately react
to detected faults/attacks.

The Speaker: Hyeong-Ah Choi is a Professor of Computer Science and
Director of the GW Center for Networks Research at the George Washington
University.  She received her Ph.D. degree in Computer Science from
Northwestern University in 1986.  Her current research interests include
networking, algorithms, network security, optical networks, and wireless
sensor networks.
