Software-defined networking touches every industry segment

There’s an inside joke in the software-defined networking industry that “SDN” stands for “still done nothing.” People say that because despite the tremendous hype around SDN, many customers remain confused about what it is, how to deploy it and what the benefits are. This is particularly true in the data center where the stakes are high and any kind of mistake can cost an organization millions of dollars.About 21 months ago, Cisco launched its Application Centric Infrastructure (ACI) solution and threw its hat in the SDN ring. In practicality, ACI is a much broader solution. It uses the principles of SDNs but deals with much more than the network.To read this article in full or to leave a comment, please click here

Hello HaLow: Your guide to the Wi-Fi Alliance’s new IoT spec

The Wi-Fi Alliance recently announced a new IEEE specification, 802.11ah, developed explicitly for the Internet of Things (IoT). Dubbed HaLow (pronounced HAY-Low), it’s aimed at connecting everything in the IoT environment, from smart homes to smart cities to smart cars and any other device that can be connected to a Wi-Fi access point.Here’s what you need to know about HaLow.1. What are the potential advantages of HaLow?First, HaLow operates in the 900-MHz band. This lower part of the spectrum can penetrate walls and other physical barriers, which means better range than the current 2.4GHz and 5GHz Wi-Fi bands.To read this article in full or to leave a comment, please click here

10 things we love about the new Firefox browser

Loving FirefoxRemember when you ditched Firefox for Chrome and pinkie-swore you’d never go back? Yeah, me too. But recently I needed to test one of our web-based apps in Firefox, so, with some hesitance, I took the plunge and installed it. Turns out, the good folks at Mozilla took their vanishing market share to heart and fought back with one of the most notably improved products I have seen in recent memory. Here are 10 things we love about Firefox. (Read the full story.)To read this article in full or to leave a comment, please click here

BMW’s vision for a world of connected cars

As you’re brushing your teeth in the morning you monitor a digital display mirror that shows all your relevant information for the day: Schedule of appointments, weather and battery levels of all your devices, including your phone and BMW i3 electric car in the garage.As you walk into your kitchen and turn on your coffee machine, that’s the cue your car has been waiting for to turn itself on and begin to warm up. Time to go: With a swipe on your touch-enabled car key, the vehicle detaches from its charging unit, pulls out of the garage and up to your front door. It’s already calculated the best route to your first appointment, taking into account traffic and weather.To read this article in full or to leave a comment, please click here

The future of auto safety is seat belts, airbags and network technology

The 1950s saw the introduction of automobile seat belts; in the 70s, airbags began showing up in cars. Electronic Stability Controlled rolled out in the late 80s, and the last decade has seen the deployment of radar and camera-based backup assist and blind-spot warning systems.Auto safety experts say network technology could be the next major car safety innovation. “Decades from now, it's likely we'll look back at this time period as one in which the historical arc of transportation safety considerably changed for the better, similar to the introduction of standards for seat belts, airbags, and electronic stability control technology," said David Freedman, administrator for the National High Transportation Safety Agency (NHTSA) in 2014.To read this article in full or to leave a comment, please click here

Thoughts on Luminus Networks

Late last week, Cyrus Durgin from Luminus Networks published an article on SDx Central titled “The (R)evolution of Network Operations.” You may notice that my name is mentioned at the bottom of the article as someone who provided feedback. In this post, I’d like to share some thoughts—high-level and conceptual in nature—on network operations and Luminus Networks.

I was first introduced to Luminus Networks when I met its CEO, Kelly Wanser, at the Open Networking User Group (ONUG) meeting in New York City last November. We met again in the Denver area in late December, and Kelly gave me a preview of what Luminus was building. I must confess that I was immediately intrigued by what Kelly was describing. One key thing really jumped out at me: we need to treat the network as a system, not as a bunch of individual elements.

When it comes to network monitoring/management/operations, so many of the tools are focused on the individual elements that comprise a network: provisioning a switch, pushing configuration changes to a router or group of routers, polling counters from interfaces on switches, etc. While there’s nothing wrong with any of these things, it seems to me that there’s Continue reading

Docker Networking: macvlan bridge

Docker takes a slightly different approach with its network drivers, confusing new users which are familiar with general terms used by other virtualization products. If you are looking for a way to bridge the container into a physical network, you have come to the right place. You can connect the container into a physical Layer 2 network by using macvlan driver. If you are looking for a different network connection, refer to my docker network drivers post.

Before I begin, you should check some basics on what macvlan is, why it is a better alternative to a linux bridge and how it compares with ipvlan.

Important: As of Docker 1.11 macvlan network driver is part of Docker’s experimental build and is not available in the production release. You can find more info on how to use the experimental build here. If you are looking for a production ready solution to connected your container into a physical Layer 2 network, you should stick to pipework for the time being.

Last but not least, macvlan driver requires Linux Kernel 3.9 or greater. You can check your kernel version with uname -r. If you’re running RHEL (CentoOS, Continue reading

OpenNSL

Open Network Switch Layer (OpenNSL) is a library of network switch APIs that is openly available for programming Broadcom network switch silicon based platforms. These open APIs enable development of networking application software based on Broadcom network switch architecture based platforms.

The recent inclusion of the APIs needed to enable sFlow instrumentation in Broadcom hardware allows open source network operating systems such as OpenSwitch and Open Network Linux to implement the sFlow telemetry standard.

Kansas Heart Hospital hit with ransomware; attackers demand two ransoms

Kansas Heart Hospital in Witchita was hit with ransomware last week. The ransomware attack occurred on Wednesday, and the KWCH 12 news video from Friday night said some files were still inaccessible by the hospital.Hospital President Dr. Greg Duick refused to disclose the ransom amount and the ransomware variant. He said, “I'm not at liberty because it's an ongoing investigation, to say the actual exact amount. A small amount was made.”Yes, the hospital paid the ransom. No, the hackers didn’t decrypt the files—at least it was described as not returning “full access to the files.” Instead, the attackers asked for another ransom. This time the hospital refused to pay because it was no longer “a wise maneuver or strategy.”To read this article in full or to leave a comment, please click here

Boston BSides needs more space to grow

 The Boston BSides conference is bursting at its seams and may have to find a new place to carry out its mission of providing inexpensive IT security training, educational sessions and informal networking where peers can share experiences and help guide aspiring security pros.The conference this weekend at Microsoft’s New England Research and Development (NERD) Center in Cambridge, Mass., was full to capacity with about 400 people attending – the NERD limit, says Daniel Reich, one of the show’s organizers.He says the organizers had to turn away about 100 others who wanted to attend, and after reading surveys by attendees and comments on Twitter, they may be looking for a larger venue for next year.To read this article in full or to leave a comment, please click here
