When Disaster Strikes: Safeguarding Networks
WASHINGTON --(Business Wire)--
Disasters both natural and human-caused can damage or destroy data and
communications networks. Several presentations at the 2014 OFC
Conference and Exposition, being held March 9-13 in San Francisco,
Calif., USA will present new information on strategies that can mitigate
the impacts of these disasters.
New Algorithm Finds Safe Refuge for Cloud Data
Much of our computing these days, from browsing websites and watching
online videos to checking email and following social networks, relies on
the cloud. The cloud lives in data centers - massive warehouses filled
with thousands of servers that run constantly. Disasters such as
earthquakes, tornadoes, or even terrorist attacks, can damage the data
centers and the communication links between them, causing massive losses
in data and costly disruptions.
To mitigate such potential damage, researchers from the University of
California, Davis (UC Davis), Sakarya University in Turkey, and
Politecnico de Milano in Italy, first analyzed the risk that a disaster
may pose to a communications network, based on the possible damage of a
data center or the links that connect them to users. Then, they created
an algorithm that keeps data safe by moving or copying the data from
data centers in peril to more secure locations away from the disaster.
The algorithm assesses the risks for damage and users' demands on the
network to determine, in real-time, which locations would provide the
safest refuge from a disaster.
"Our content placement solution can be implemented with some
modifications on any existing settings of ata centers and it is
adaptable to different dynamic disaster scenarios," said researcher
Sifat Ferdousi of UC Davis. "This can highly benefit the network
providers in designing disaster-resilient cloud networks."
Presentation M2H.4 titled, "Disaster-Aware (News - Alert) Dynamic Content Placement in
Optical Cloud Networks" will take place Monday, March 10 at 3:15 p.m. in
room 130 of the Moscone Center. The work was done as part of a research
project at UC Davis funded by the U.S. Defense Threat Reduction Agency.
Integrating Wireless with Fiber for Temporary Emergency Networks
Earthquakes, tsunamis, and other natural disasters can sever the optical
fibers that carry data across long distances, leaving telecommunications
networks useless. If fiber-optic cables are down, wireless communication
can fill the void and be part of a temporary, emergency network. But for
such a system to work, wireless technology would have to be integrated
with the fiber-optic network that transports data around the world.
Such an integrated wireless optical system would combine the speed and
bandwidth of fiber optics with the mobility and range of a wireless
network. This system could also be applied in home networks, in which
data is sent via optical cables to the home then broadcasted wirelessly.
One big challenge of an integrated system, however, is to develop the
wireless links that can handle the speed and capacity of optical cables.
Researchers from Fudan University in Shanghai and ZTE (News - Alert) (TX), Inc. in
Morristown, N.J., USA have now developed a new antenna architecture that
allows for a simple and high-speed integrated wireless optical system.
The design relies on two pairs of antennas, explains Jianjun Yu of ZTE.
Because each pair is polarized differently and isolated, there's no
interference between the two pairs, allowing for a simpler structure and
a larger transmission capacity. The new system achieves a
data-transmission rate of 146 gigabits per second (Gb/s), which is the
highest bit-rate-per-channel in a wireless signal shown so far, Yu says.
Presentation M2D.7 titled, "Antenna Polarization Diversity for 146 Gb/s
Polarization Multiplexing QPSK Wireless Signal Delivery at W-band" will
take place Monday, March 10 at 5:30 p.m. in room 122 of the Moscone
PRESS REGISTRATION: A press room for credentialed press and analysts
will be located in the Moscone Center, Sunday through Thursday, March
9-13. Those interested in obtaining a press badge for OFC should contact
Lyndsay Meyer at 202.416.1435 or firstname.lastname@example.org.
For more than 35 years, OFC has been the premier destination for
converging breakthrough research and innovation in telecommunications,
optical networking, fiber optics and, recently, datacom and computing.
Consistently ranked in the top 200 tradeshows in the United States, and
named one of the Fastest Growing Trade Shows in 2012 by TSNN, the
conference unites service providers, systems companies, enterprise
customers, IT businesses, and component manufacturers, with researchers,
engineers, and development teams from around the world. OFC includes
dynamic business programming, an exposition of more than 550 companies,
and cutting-edge peer-reviewed research that, combined, showcase the
trends and pulse of the entire optical networking and communications
industry. OFC is managed by The Optical Society (OSA) and co-sponsored
by OSA, the IEEE (News - Alert) Communications Society (IEEE/ComSoc), and the IEEE
Photonics Society. OFC 2014 takes place March 9-13 at the Moscone
Convention Center in San Francisco, Calif., USA.
