Harvesting ambient energy will power IoT, scientists say

Stray, ambient magnetic fields that are naturally created from electricity usage should be captured, diverted, and converted into power for Internet of Things sensors, researchers say."Just like sunlight is a free source of energy we try to harvest, so are magnetic fields," said Shashank Priya, professor of materials science and engineering and associate vice president for research at Penn State, in a statement published on the university's web site. "We have this ubiquitous energy present in our homes, office spaces, work spaces and cars. It's everywhere, and we have an opportunity to harvest this background noise and convert it to useable electricity."To read this article in full, please click here

Pushing BGP Flowspec rules to multiple routers

Real-time DDoS mitigation using BGP RTBH and Flowspec describes the open source DDoS Protect application. The software runs on the sFlow-RT real-time analytics engine, which receives industry standard sFlow telemetry from routers and pushes controls using BGP. A recent enhancement to the application pushes controls to multiple routers in order to protect networks with redundant edge routers.

ddos_protect.router=10.0.0.96,10.0.0.97

Configuring multiple BGP connections is simple, the ddos_protect.router configuration option has been extended to accept a comma separated list of IP addresses for the routers that will be connecting to the controller.
Alternatively, a BGP Flowspec/RTBH reflector can be used to propagate the controls. Flowspec is a recent addition to open source BGP software, FRR and Bird, and it should be possible to use this software to reflect Flowspec controls. A reflector can be a useful place to implement policies that direct controls to specific enforcement devices.

Support for multiple BGP connections in the DDoS Protect application reduces the complexity of simple deployments by removing the requirement for a reflector. Controls are pushed to all devices, but differentiated policies can still be implemented by configuring each device's response to controls.

Offer of Assistance to Governments During COVID-19

As the COVID-19 emergency continues to affect countries and territories around the world, the Internet has been a key factor in providing information to the public. As businesses, organizations and government agencies adjust to this new normal, we recognize the strain that this pandemic has put on the groups working to assist in virus mitigation and provide accurate information to the general public on the state of the pandemic.

At Cloudflare, this means ensuring that these entities have the necessary tools and resources available to them in these extenuating circumstances. On March 13, we announced our Cloudflare for Teams products will be free until September 1, 2020, to ensure Cloudflare users and prospective users have the tools they need to support secure and efficient remote work. Additionally, we have removed usage caps for existing Cloudflare for Teams users and are also providing onboarding sessions so these groups can continue business in this new normal.

As a company, we believe we can do more and have been thinking about ways we can support organizations and businesses that are at the forefront of the pandemic such as health officials and those providing relief to the public. Many organizations have reached out to Continue reading

Q&A with Devo: COVID-19 Is Changing the Cloud Conversation

How do companies manage the security implications of working from home, in a country where remote work has generally been frowned on? Devo, a data analytics and security platform with headquarters in Madrid, helps companies get visibility into their networks — something that has become even more critical as more companies rely on virtual private network (VPNs) to security connect team members working from home.  We spoke with Devo, and carloyuen from

When All You Have Are Stretched VLANs…

Let’s agree for a millisecond that you can’t find any other way to migrate your workload into a public cloud than to move the existing VMs one-by-one without renumbering them. Doing a clumsy cloud migration like this will get you the headaches and the cloud bill you deserve, but that’s a different story. Today we’ll talk about being clumsy the right and the wrong way.

There are two ways of solving today’s challenge:

IBM extends z15 mainframe family, intensifies Linux security

IBM continued to reshape the mainframe with an eye toward further integrating it within hybrid clouds and securing Linux-based workloads.On the hardware side, IBM rolled out two entry-level, 19” single-frame, air-cooled platforms, the  z15 Model T02 and LinuxONE III Model LT2. The new machines are extensions of the IBM z15 family that Big Blue rolled out in September of last year. To read this article in full, please click here

How to dispose of IT hardware without hurting the environment

Many enterprises don’t think much about where their obsolete IT gear winds up, but it’s possible to be green-minded, not bust the budget, and even benefit a little from proper disposal. Here is how.Go back to where you bought The first option to consider is returning the equipment the vendor or reseller you bought it from, says Susan Middleton, research director, financing strategies at IDC. “Every year we ask customers, ‘How do you handle end-of-lease?’ Overwhelmingly, they return to vendor or partner who are better equipped to handle recycling,” she says.[Get regularly scheduled insights by signing up for Network World newsletters.] Vendors often give a fair-market buyout for the devices that can go toward new products, Middleton says. “The big players like IBM and HPE do a great job because they can clean them up and resell them, and the facilities to do that are pretty big,” she says.To read this article in full, please click here

Introducing the Calico eBPF Dataplane

eBPF is a hot topic right now; most of the infrastructure-focused conferences and events have included talks on eBPF over the past year, which is creating a lot of interest in the technology.

You might be wondering what eBPF is. eBPF stands for “extended Berkeley Packet Filter” which is a feature in modern Linux kernels that allows you to write mini-programs that are attached to low-level hooks in the Linux kernel, that execute based on certain events (e.g. filtering network traffic). While Calico is primarily focused on networking and security use cases, eBPF is a broad technology that applies to many other use cases as well.

We’ve always been tracking eBPF and it’s potential to enhance Calico, however, most users have not been ready for it. Improving on Calico’s already excellent dataplane using eBPF requires the latest Linux kernels, that are not always available to our enterprise customers that require a vendor-supported Linux distribution to run in production. Nevertheless, we decided to add an eBPF dataplane to support those users that are able to use the latest Linux kernels, as well as provide a future-proofed path for those who will wait until their vendor-supported Linux distributions will support the Continue reading

The Network Impact of the Global COVID-19 Pandemic

With so many countries in lockdown and so many people working (and learning) from home, online usage has risen significantly but so far, the internet is holding up well. Internet traffic is generally to 25% to 30% higher than usual, and what we do online is also changing. Internet usage often increases goes up in a typical month; for Akamai that’s usually 3% growth, in the last month it’s been 30%. In March 2019 their peak traffic was 82Tbps; this March it was 167Tbps and the sustained daily traffic rate is higher than last year’s peak for March. Internet exchanges in Amsterdam, Frankfurt and London saw 10-20% increases in traffic around March 9th, which the exchange in Milan had a 40% increase the day Italy was quarantined. Disturbingly, attacks are up too: Akamai Cloudflare tracks varies by city; it’s only up 11% in Berlin and 22% in London between early January and late March (and 17% up for the UK as whole), but it’s grown by 40% in New York and 48% in San Francisco and Silicon Continue reading
