When ESnet engineers began to study the idea of building a new 100 Gbps network between the US and Europe, a primary concern was ensuring the service would be robust and built from multiple underlying links — so that if one went down, researchers could still rely on sufficient bandwidth. Based on data collected by Caltech physicist and networking pioneer Harvey Newman, the team understood multiple cables are sometimes cut simultaneously.
SX1400, SX1700 and SX1710 Ethernet switches are top-of-rack Open Ethernet software-defined networking (SDN) 10/40/56 Gigabit switches. Based on Mellanox’s SwitchX-2 switch ICs, they provide enhanced control plane capabilities and allow for the design of hyperscale data center networks and control-intensive cloud applications.
As with the proverbial canary in the coal mine, birds serve as an indicator of the health of our environment. Many common species have experienced significant population declines within the last 40 years. Suggested causes include habitat loss and climate change, however to fully understand bird distribution relative to the environment, extensive data are needed.
NASA has formally delivered to Alaskan officials a new technology that could help pilots flying over the vast wilderness expanses of the northern-most state. The technology is designed to help pilots make better flight decisions, especially when disconnected from the Internet, telephone, flight services and other data sources normally used by pilots.
Mellanox Technologies a supplier of interconnect solutions for servers and storage systems, has announced that its end-to-end 10 and 40 Gigabit Ethernet interconnect solutions support the recently announced IBTA RoCEv2 specification.

Big Data, it seems, is everywhere, usually characterized as a Big Problem. But researchers at Lawrence Berkeley National Laboratory are adept at accessing, sharing, moving and analyzing massive scientific datasets. At a July 14-16, 2014, workshop focused on climate science, Berkeley Lab experts shared their expertise with other scientists working with big datasets.
In my 15 or so years leading the charge for Ethernet into higher speeds “high performance computing” and “research and development” have always been two areas that the industry could count on where higher speeds would be needed for its networking applications. For example, during the incarnation of the IEEE 802.3 Higher Speed Ethernet Study Group that looked beyond 10GbE, and ultimately defined the 40 Gigabit and 100 Gigabit Ethernet ...
It is the central means of communication of our times: Electronic mailing. Worldwide, short messages as well as large data packages can be exchanged rapidly and at low costs. 30 years ago, the first e-mail arrived in Germany at the then Universität Karlsruhe (TH), today’s Karlsruhe Institute of Technology. It was the first Internet-based connection between the American network CSNET (Computer Science Net) and the new Karlsruhe CSNET server.
Scientists from AT&T, IBM and ACS announced a proof-of-concept technology that reduces set up times for cloud-to-cloud connectivity from days to seconds. This advance is a major step forward that could one day lead to sub-second provisioning time with IP and next-generation optical networking equipment and enables elastic bandwidth between clouds at high connection request rates using intelligent cloud data center orchestrators.
HPC-X Scalable Software Toolkit is a comprehensive software suite for high-performance computing environments that provides enhancements to significantly increase the scalability and performance of message communications in the network. The toolkit provides complete communication libraries to support MPI, SHMEM and PGAS programming languages, as well as performance accelerators that take advantage of Mellanox scalable interconnect solutions.
IBM is making high performance computing more accessible through the cloud for clients grappling with big data and other computationally intensive activities. A new option from SoftLayer will provide industry-standard InfiniBand networking technology to connect SoftLayer bare metal servers. This will enable very high data throughput speeds between systems, allowing companies to move workloads traditionally associated with HPC to the cloud.
Big Web sites usually maintain their own “data centers,” banks of tens or even hundreds of thousands of servers, all passing data back and forth to field users’ requests. Like any big, decentralized network, data centers are prone to congestion: Packets of data arriving at the same router at the same time are put in a queue, and if the queues get too long, packets can be delayed.
Mathematical equations can make Internet communication via computer, mobile phone or satellite many times faster and more secure than today. Results with software developed by researchers from Aalborg University in collaboration with the Massachusetts Institute of Technology (MIT) and California Institute of Technology (Caltech) are attracting attention in the international technology media.
Internet access is becoming increasingly mobile, and the next billion users will experience the Internet in new ways from those already online. The experience of Internet connectivity is far from uniform, and observing the variety of connectivity, and how it is changing over time is important. Smartphone users around the globe can download an app and contribute their measurements to a global picture of Internet diversity and evolution.
In quantum mechanics, interactions between particles can give rise to entanglement, which is a strange type of connection that could never be described by a non-quantum, classical theory. These connections, called quantum correlations, are present in entangled systems even if the objects are not physically linked. Entanglement is at the heart of what distinguishes purely quantum systems from classical ones — why they are potentially useful.
For the past 21 years, the TOP500.org has been ranking supercomputers by their performance on the LINPACK Benchmark. Reported two times a year, the release of the list is anticipated by the industry. As with any such ranking, the top of the list often garners the most attention. However, such emphasis on the top of such a list, would limit one’s understanding of the different supercomputers in the TOP500...
Washington State University has developed a wireless network on a computer chip that could reduce energy consumption at huge data farms by as much as 20 percent.
In the coming decades, we will likely commute to work and explore the countryside in autonomous, or driverless, cars capable of communicating with the roads they are traveling on. A convergence of technological innovations in embedded sensors, computer vision, artificial intelligence, control and automation, and computer processing power is making this feat a reality.
Internet regulation in the United States is potentially facing a major change. FCC Internet Neutrality rules — also referred to as Net Neutrality rules — currently apply, but thanks to pressure from Internet Service Providers (ISP), legislators and recent court rulings, that might change. You have undoubtedly heard the term Net Neutrality before, but may be at a loss regarding what it means or what its implications are.
If future generations were to live and work on the moon or on a distant asteroid, they would probably want a broadband connection to communicate with home bases back on Earth. They may even want to watch their favorite Earth-based TV show. That may now be possible thanks to a team of researchers from MIT's Lincoln Laboratory who, working with NASA last fall, demonstrated for the first time that a data communication technology exists ...

Data transfers from the Large Hadron Collider at CERN in Switzerland to sites in the U.S. have historically taken different paths — 15 in all — via 10 gigabit per second (Gbps) links separately managed by three research networks in the U.S. and Europe. So, what would happen if those massive datasets were instead transferred using a single 100 Gbps connection?
