MCI Inc. teamed with Xtera Communications, Mintera Corp., and Juniper Networks
to successfully transmit 40 Gigabits per second (Gbps) over 3,040 km of
field fiber in MCI's Dallas metro area network. This milestone
demonstrates that next generation technology is now available to
support high-bandwidth IP traffic demands over Ultra Long Haul (ULH)
distances on existing fiber infrastructure while maintaining reliable
"MCI continues to lead the industry in technology innovation and the
delivery of next generation IP services," said Jack Wimmer, MCI vice
president of Network Architecture and Advanced Technology. "As we
execute on our IP convergence strategy, and as customer applications
drive bandwidth onto our network, 40 Gbps transmission becomes an
increasingly important technology to enable efficient scaling of our
The technology field trial, which was conducted in October and
November, carried 74 channels of 10 Gbps traffic and 2 channels of 40
Gbps traffic over 38 individual 80 km spans of standard single mode
fiber around the Dallas metro area using the Xtera all-Raman DWDM
system, Mintera advanced modulation format long reach OC768
transponders, and Juniper Networks T640 IP routers with OC768 short
Using patented all-Raman technologies, Xtera's Nu-Wave Multi-Reach
DWDM platform supports 40 Gbps transmission with unprecedented reach,
extremely high bandwidth, and extensive Optical Add-Drop Multiplexer
(OADM) flexibility to deliver high-quality video, data and advanced
This all-Raman amplifier allows the optical signal to be carried a
greater distance with three times the capacity of most traditional
Erbium Doped Fiber Amplifiers (EDFA). As a result, an all-Raman
approach can translate into lower network costs, increased reliability,
reduced infrastructure builds, simplified channel engineering and
streamlined capacity planning.
Mintera's MI 40000 optical transport equipment enables carriers to
deploy 40 Gbps wavelengths without traffic interruption on
infrastructures designed for, and simultaneously, carrying lower
bit-rate signals. A variety of modulation formats, including DPSK, are
employed to permit this boost in bandwidth efficiency to be implemented
without adding regeneration sites, thus significantly lowering overall
Juniper Networks OC768c router interface enables carriers to
increase the efficiency and capacity of IP networks to better support
bandwidth-intensive applications and services. The Juniper Networks
T-series routing platform offers a combination of advanced routing
features, IP/MPLS capabilities, reliability and scale to support
high-capacity core applications. In combination with the JUNOS software
feature set, the T-series provides the flexibility and scale to help
meet growing bandwidth capacity requirements.
MCI originally demonstrated high-capacity Internet technology in May
2004 when the company successfully transmitted the world's first 40
Gbps IP traffic using MCI optical network fiber between San Francisco
and San Jose, Calif. That was followed weeks later with MCI
extending the reach of 40 Gbps wavelengths to 1,200 km, using the
company's ULH backbone network between Sacramento, Calif., and Salt
Frank Ding, engineering analysis & technical computing manager at Simpson Strong-Tie, discussed the advantages of utilizing the cloud for occasional scientific computing, identified the obstacles to doing so, and proposed workarounds to some of those obstacles.
The private industry least likely to adopt public cloud services for data storage are financial institutions. Holding the most sensitive and heavily-regulated of data types, personal financial information, banks and similar institutions are mostly moving towards private cloud services – and doing so at great cost.
In this week's hand-picked assortment, researchers explore the path to more energy-efficient cloud datacenters, investigate new frameworks and runtime environments that are compatible with Windows Azure, and design a uniﬁed programming model for diverse data-intensive cloud computing paradigms.

When it comes to cloud, long distances mean unacceptably high latencies. Researchers from the University of Bonn in Germany examined those latency issues of doing CFD modeling in the cloud by utilizing a common CFD and its utilization in HPC instance types including both CPU and GPU cores of Amazon EC2.

For engineers looking to leverage high-performance computing, the accessibility of a cloud-based approach is a powerful draw, but there are costs that may not be readily apparent.
05/10/2013 | Cleversafe, Cray, DDN, NetApp, & Panasas | From Wall Street to Hollywood, drug discovery to homeland security, companies and organizations of all sizes and stripes are coming face to face with the challenges – and opportunities – afforded by Big Data. Before anyone can utilize these extraordinary data repositories, however, they must first harness and manage their data stores, and do so utilizing technologies that underscore affordability, security, and scalability.
04/02/2012 | AMD | Developers today are just beginning to explore the potential of heterogeneous computing, but the potential for this new paradigm is huge. This brief article reviews how the technology might impact a range of application development areas, including client experiences and cloud-based data management. As platforms like OpenCL continue to evolve, the benefits of heterogeneous computing will become even more accessible.
