IDG Contributor Network: Leveraging reconfigurable computing for smarter cybersecurity, part 2

In my last column, I looked at the challenges facing security teams today and, in particular, the need for more intelligent cybersecurity solutions, more powerful cybersecurity appliances and faster response to security incidents. We also looked at how reconfigurable computing solutions are addressing the need for more powerful appliances and enabling faster response to security incidents. In part 2, we will dive deeper into the latest developments in enabling more intelligent and comprehensive cyber security solutions and how reconfigurable computing can make a difference.To read this article in full, please click here

IDG Contributor Network: 5 predictions for the Internet of Things in 2018 and beyond

The Internet of Things (IoT) has started to move to the mainstream in enterprises across all industries. With IoT spending set to increase by 15 percent to reach $772.5 billion by the end of 2018, the coming year will undoubtedly bring further growth in the number of connected devices and enterprise IoT projects. More importantly, I believe that in 2018 enterprise IoT projects will finally move beyond merely automating existing business processes, to truly transforming industries by creating entirely new revenue streams and business models. This will be due in part to the concurrent rise of synergistic technologies such as artificial intelligence (AI) and fog computing, as well as an industry-wide move toward greater interoperability, standards and collaboration.To read this article in full, please click here

SD-WAN deployment options: DIY vs. cloud managed

So you’re ready to deploy an SD-WAN.

Measuring Network Bandwidth using Iperf and Docker

At the heart of any network engineer’s toolkit, are applications that let you peer into the network for performance, congestion and capacity planning. One of the thoroughbreds in the open source network tools collection is iperf. Iperf has been around for a long time. The good folks at ESnet updated the original iperf with new features and what not and ... The post Measuring Network Bandwidth using Iperf and Docker appeared first on NetworkStatic | Brent Salisbury's Blog.

What’s Your Biggest Professional Challenge?

Now that we are in a new year (wow, it is hard to believe it is 2018), I want to ask a simple question. With what you are trying to accomplish at work or in your career, what is your biggest challenge? Is it something only you can deal with or is it something that someone can help with? Would you consider this challenge a personal challenge for your own career goals, or is it a challenge that you are trying to solve to further your employer’s objectives?

For me the answer would be something like this–

  1. Biggest Professional Challenge–distractions
  2. Who can help with this–mostly me, but my employer certainly doesn’t help and probably doesn’t truly understand the efficiencies that could be gained.
  3. This is a personal challenge–but my employer could certainly reap the rewards if I could improve in this area.

I wouldn’t necessarily consider this my resolve for 2018. However, it is certainly an area that I will work hard to improve in this new year. 

What are your challenges? Maybe I could help. Maybe it could even be interesting enough to be a new distraction that steals all my attention and becomes a new area of complete Continue reading

Worth Reading: Network Applications are Interactive

The proliferation of mobile devices and the interconnectivity between them has created new application opportunities. These new applications are no longer limited to a single system space but are spread across many system spaces. This shift of application from single system-spaced, host-based systems to multisystem-spaced solutions is being hampered by software toolsets that are stuck in the older sequential computational models. —Antony Alappatt @The Association of Computing Machinery

2018: Advocacy and Action

Happy New Year!

2018 offers exciting promise and opportunity for the Internet Society and the work of our global community for a better Internet. We’ll continue the positive momentum we started in 2017, when we celebrated our 25 year milestone and strengthened our impact around the globe.

Thank you to all who joined us on this amazing journey.  Take a look back at many of last year’s highlights.

Our ongoing mission to protect and to shape the Internet for future generations is not an easy task. However, we are well positioned with the people, resources, and commitment from across our global community to be a bold, powerful force for change.

To carry forward our focus on access and trust as the two most pressing issues facing the Internet today, in 2018 we will execute our Action Plan that outlines our advocacy efforts in these areas with a detailed set of priorities for maximum impact. In addition, we will continue to extend our community and organization to build a stronger foundation for realizing our vision, and foster new initiatives that respond to today’s rapidly changing world.

While I have announced my plans to pass on the CEO baton once the Continue reading

VXLAN routing with EVPN: asymmetric vs. symmetric model

We all know and love EVPN as a control plane for VXLAN tunnels over a layer 3 infrastructure (Need a refresher? Check out our blog post on the topic). EVPN gives us the ability to deploy VXLAN tunnels without controllers. Plus, it offers a range of other benefits such as reduction of data center traffic through ARP suppression, quick convergence during mobility, one routing protocol for both underlay and overlay and the inherent ability to support multi-tenancy (just to name a few). So EVPN for VXLAN for all of your layer 2 needs, right? Well it’s a little more complicated than that.

Customers need to also communicate between VXLANs and between a VXLAN tunnel and the outside world, so VXLAN routing must also be enabled in the network — which is what I cover in this post. Previous generation merchant silicon does not internally support VXLAN routing, so customers implement a workaround — adding an external loopback cable, sometimes called hyperloop, to the switch. The newer chips that support VXLAN routing allow us to route directly on the ASIC, eliminating the need for the hyperloop.

VXLAN routing can be performed with one of two architectures – centralized or distributed. Continue reading

Secure your SDN controller

Managing networks has become increasingly complex, and it will remain a challenge as the use of Internet of Things devices continues to grow. This complexity makes it difficult to reconfigure a traditional network in a timely manner to respond to malicious events or fix configuration errors.A software-defined network (SDN) can help by giving network engineers the flexibility to dynamically change the behavior of a network on a node-by-node basis — something not typically available in a traditional network. An SDN uses virtualization to simplify the management of network resources and offers a solution for increased capacity without significantly increasing costs.To read this article in full, please click here

The Humble API

Network Engineering and coding, like many other things in the information technology world, share overlapping concepts—even if we don’t often recognize the overlap because we are too busy making up new names to describe the same thing. For this week’s video, I turn my attention to the Application Programming Interface, or the API.
