National Science Foundation doles out $12M for wireless growth

The U.S. National Science Foundation yesterday handed out 11 grants, totaling $12 million, to researchers working on bringing the benefits of the public airwaves to more Americans than ever before.The awards went to researchers at a diverse range of educational institutions, including the U.S. Naval Academy, Virginia Tech, Wisconsin, and Texas A&M, among others. The research itself tended to center on work that makes spectrum sharing easier, freeing up space across the increasingly crowded airwaves.Specifically the NSF said the awards were directed at four major areas, including: Innovative radio hardware and access architectures to enable spectrum sharing. Harmonious co-existence of heterogeneous wireless technologies. Development of automated detection mechanisms and compliance certification methods. Spectrum access for science services. +ALSO ON NETWORK WORLD: With help from Docker, Google's Go jumps in popularity + Wi-Fi vs. LTE could be the start of a mobile rollercoasterTo read this article in full or to leave a comment, please click here

Game on: Alienware’s 20-year affair with gaming helps drive the future of VR

Alienware co-founder Frank Azor has fond memories of the comany's early days. It was a wild time of building kick-ass PCs, gaming, lots of sci-fi shows and generally, having a good time. "It was four guys in a tiny little office, sending in a couple of review machines, magazines saying they were great, and the phone beginning to ring very, very slowly. We would sell about one computer every day, maybe," Azor said. October 15 marks 20 years of Alienware's existence. Now a part of Dell, Alienware has matured into a PC gaming powerhouse. It is also driving big changes for virtual and mixed reality, which Azor believes will drive PC growth in the coming decades.To read this article in full or to leave a comment, please click here

Nurturing tomorrow’s techies STEMs from promoting technology in schools

With the school year underway, I’m reminded about the critical role that education and technology play in our future. Whatever your role—parent, teacher, student, mentor, employer, employee—technology literacy needs to be a priority. For those involved with elementary school students, the best place to start is emphasizing education that promotes science, technology, engineering and math (STEM). + Also on Network World: STEM majors dominate salary-based college ranking +STEM programs offer an excellent opportunity to infuse technology into the learning process early on. Business and education experts agree that STEM education better prepares students and opens the door for greater career options. A STEM-based education is important because some element of science, technology, engineering and/or math is evident in most well-paying jobs. A recent article in Network World stated a majority of the highest-paying college majors are in engineering, led by petroleum engineers with a mid-career median salary of $172,000, according to Payscale. To read this article in full or to leave a comment, please click here

Samsung cuts revenue and profit forecast after Note7 fiasco

Samsung Electronics has cut its revenue and profit forecasts for the third quarter, after the disastrous launch of its flagship Galaxy Note7, which eventually led to the company recalling the smartphones and stopping their production in the wake of reports of overheating batteries.The South Korean company said Wednesday that revenue for the quarter was likely to be about 47 trillion won (US$4.2 billion), down from the 49 trillion won that it had expected earlier this month in a preliminary forecast. Operating profit is expected to drop by about 2.6 trillion won to 5.2 trillion won.The company said it was revising its revenue and profit forecast because of the Note7 debacle.To read this article in full or to leave a comment, please click here

Do I Need Redundant Firewalls?

One of my readers sent me this question:

I often see designs involving several more than 2 DCs spread over different locations. I was actually wondering if that makes sense to bring high availability inside the DC while there's redundancy in place between the DCs. For example, is there a good reason to put a cluster of firewalls in a DC, when it is possible to quickly fail over to another available DC, as a redundant cluster increases costs, licenses and complexity.

Rule#1 of good engineering: Know Your Problem ;) In this particular case:

BGP in MPLS Layer 3 VPN – BGP as a PE-CE Routing Protocol

BGP can be used as a PE-CE routing protocol in MPLS Layer 3 VPN. Also Service Providers run MP-BGP (Multiprotocol BGP) if they have MPLS Layer 3 VPN. In this article, MP-BGP will not be explained since it has been explained here earlier in detail. When BGP is used as a PE-CE routing protocol between […]

ICANN and the future of DNS and internet

How Does Internet Work - We know what is networking

I sorry to put here something that is not really technical but with a blog with the name “howdoesinternetwork.com” it would be strange not to follow the story about the future of DNS governance giving the fact that DNS is a crutial part of internet functionality. You probably know how the internet works giving the fast that you are visiting a blog like this. Regardless of that, it will not hurt to explain in few words the importance of DNS (Domain Name System) for normal internet operation.

Disruptive Technologies on the Post Exascale Horizon

Although the timeline for reaching exascale class computing continues to stretch farther into the future, research teams are keeping an eye on what technologies will shape the machines of the post-exascale timeframe, which is in the 2022-2030 timeframe.

While many of the technologies stated in a comprehensive report about post-exascale supercomputers are already in process, albeit in various stages of development and adoption, there is little consensus about which mode of computing will lead us into an era of unprecedented data and simulation potential. Still, the effort on behalf of the EuroLab-4-HPC program is notable in its divisions between where …

SkyGiraffe’s Tableau connector aims to ease business data visualization

While business intelligence software like Tableau helps companies better understand the data that they have saved up in systems of record like databases and CRM software, it can be hard to get the entire picture of a business from the plethora of different sources available.SkyGiraffe is launching a new connector Tuesday to help with that by allowing companies to take live data from a diverse set of systems of record and visualize it in Tableau. The connector is supposed to give businesses a single consistent means of visualizing data, without having to repeatedly configure a bunch of different integrations.To read this article in full or to leave a comment, please click here

BrandPost: Network Performance On Demand

Organizations today need speed and reliability, but also want flexibility and freedom to adjust their services levels and costs to meet changing needs. As health care providers shift to electronic records and files, they’re finding the need to scale up network performance but in a cost-conscious environment are wary about locking themselves into expensive options they need only for high-peak periods.For the Austin Cancer Center, huge imaging files can be a vital component of diagnosis and treatment. But moving large data sets such as digital PET scan images of a gigabyte or more between the 12 campuses in the system would create a huge bottleneck over most enterprise Ethernet LANs, or a huge expense to create peak capacity that is often underutilized.To read this article in full or to leave a comment, please click here

Ganging up Accelerators to Beat Scale Limits

It is not news that offloading work from CPUs to GPUs can grant radical speedups, but what can come as a surprise is that scaling of these workloads doesn’t change just because they run faster. Moving beyond a single node means encountering a performance wall, that is, unless something can glue everything together so it can scale at will.

There are already technologies that can take multiple units of compute and have them share work from supercomputing and other areas (consider ScaleMP, for instance) but there are limitations to these approaches and thus far, they haven’t extended to meet the …
