TOAN LAB AT UA
The TOAN Testbed Provides state of the art optical transmission
and switching system platforms for prototyping device and
sub-system performance. New tools are under development
to provide software defined networking test and inter-operability
services for
optical devices and systems. Research in the testbed focuses on optical
transmission
system control including real-time fast wavelength reconfiguration, integrated photonic
devices, software defined networking (SDN), 100Gb/s coherent transmission, and optical performance
monitoring.
An SDN controlled fiber optic network that supports real time optical switching will exhibit a cy-
ber physical network interdependence with the ‘cyber’ data network over which the SDN control is
communicated. This figure, to the right, illustrates the complex inter-dependencies that can arise
between nodes in the two different networks.
In the Lab
Together with the data center testbed at UC San Diego, TOAN serves as the main testbed facility for the CIAN center.
Faculty and industry partners in the center regularly make use of its unique capabilities. The testbed is under the di-
rection of Dr. Kilper. He manages the lab and together with his team supports the testbed use by other CIAN partners,
while also using the lab for their own novel research activities.
Applications
Connectivity to networks such as the Internet is essen-
tial across society and a critical part of the infrastructure
in a metropolitan area. The capabilities investigated in
the TOAN Testbed would enable optical networks, the
plumbing and roadways of the Internet, to be reconfig-
ured on demand in response to the changing network
requirements in urban areas. Through the innovation in
TOAN, traffic bottlenecks can be rapidly resolved and
high bandwidth applications such as big data, telemed-
icine, and video can be flexibly moved to high capacity
express-ways.

The Up-and-Coming Research
The TOAN testbed is using fast laser tuning
and controls to mitigate the power dynamics
in optical networks. This technology enables
fast, real-time wavelength reconfiguration in
a larger metro network. New SDN methods are
studied in order to organize and manage multi-
layer network systems and to optimize the
performance of both data centers and wide area
or aggregation networks.
