SDN with Big Data Analytics for an Intelligent Network

Software, cloud computing and IOT are rapidly transforming networks in a way, and at a rate, never seen before. With software-as-a-service (SaaS) models, enterprises are moving more and more of their critical applications and data to public and hybrid clouds. Enterprise traffic, that never left the corporate network, is now shifting to the Internet, reaching out to different data centers across the globe. Streaming Video (Netflix, Youtube, Hulu, Amazon) accounts for an absurdly high percentage of traffic in the Internet and content providers have built out vast content distribution networks (CDNs) that overlay the Internet backbone. Higher resolutions (HD and UHD) will increase the traffic further, and by some accounts, will be over 80% of the total network traffic by 2020. More and more businesses are being created that reach their customers exclusively over the Internet (Spotify, Amazon, Safari, Zomato, etc). Real-time voice and video communications are moving to cloud-based delivery and network operators are challenged to deliver these services without impacting user quality of experience. And if this was’nt enough, with the advances being made in IOT, we have more devices than ever, lively communicating and chatting in real time over the Internet.

Security becomes a prime concern as Continue reading

Worth Reading: The Smart Home Battle Front

The fragility of “smart homes” was brought to the forefront this week as a letter made the rounds allegedly sent by an ISP to its customers noting that those accused of repeated online copyright infringement activity could have their internet access suspended. Such a letter is hardly remarkable in today’s copyright aware environment, but what made this one stand out is the ISP’s notice that suspension of a user’s internet connection “may affect other services which you may have connected to your internet service, such as the ability to control your thermostat remotely or video monitoring services.” Does this really mean our ISP has the ability to cut off our heat in the middle of the winter? —Kalev Leetaru @ Forbes

IDG Contributor Network: Is it time for a network tax cut?

It is truly remarkable to what extent corporate and personal behavior is dictated by tax policy. Much of the discussion in our nation’s capital in regard to tax reform has been about competitiveness as a rational to lower corporate tax rates. It appears as though the United States charges a 20 percent higher tax rate than much of the rest of the world, forcing corporations to shift some operations and assets into lower tax rate jurisdictions. It’s safe to say that tax policy impacts behavior in measurable ways.Just yesterday I was speaking with a communications service provider analyst. We discussed the overhead of SD-WAN tunnels. I showed the math of how it can tax various protocols. The tax for various protocols was:To read this article in full, please click here

OVN and Red Hat Virtualization: Installing OVN

Hi folks, in the last article I provided an overview and introduction to OVN. This time around, I’ll provide a walkthrough on how to actually install it in your RHV environment. My colleague Tony created an Ansible playbook to automate the installation, and I’ll share the link to that at the end. Let’s get started.

Necessary Channels and Subscriptions

One of the first thing that Tony covers in the demo is that he used the standard channels for both RHV-M (engine) and Hosts (hypervisors) – nothing special is needed from a subscription standpoint as all of the packages are now included in RHV 4.1. Using the `ovs-vsctl show` command, we see that even though the openvswitch package is pulled in as part of the host install, nothing is configured by default.

Automate the Installation with Ansible

Next, we see Tony’s Ansible playbook. It covers 2 plays, one for the engine (RHV-M) and one for the hosts. Not only does it install the packages, but it configures firewalld. Specifically, the playbook does the following:

On the Engine:

It installs “ovirt-provider-ovn” package then it starts/restarts multiple services, north and southbound connections are set.

On the Hosts:

It installs the “ovirt-provider-ovn-driver” package. Continue reading

IDG Contributor Network: 3 ways networking will change for the better in 2018

As I discussed in "Why web-scale is the future," over the past year, we’ve seen more organizations embrace it as the “go-to” model for flexible, resilient and on-demand infrastructure. Gartner predicts that by 2020, 40% of global enterprise CIOs will have initiated a corporate web-scale IT initiative.As web-scale principles continue their rise within large enterprises, the role the network plays for the business, as well as the day-to-day working lives of network engineers, will change in some pretty significant ways in the year ahead.1. Networks will help fuel digital transformation rather than slow it down 40 percent of CEOs rank digital transformation as their top imperative, according to a recent Economist Intelligence Unit survey. More than ever, digital transformation is crucial to business success; in 2018, spending on the software, hardware and services that enable digital transformation will reach nearly $1.3 trillion, predicts analyst firm IDC. This figure “represents a 16.8 percent jump compared to the $1.1 trillion spent this year,” according to Datamation.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

Looking Back: 2017 Project Report Card

As has become my custom for the past several years, I wanted to take a look at how well I fared on my 2017 project list. Normally I’d publish this before the end of 2017, but during this past holiday season I decided to more fully “unplug” and focus on the truly important things in life (like my family). So, here’s a look back at my 2017 projects and a report card on my progress (or lack thereof, in some cases).

For reference, here’s the list of projects I set out for myself in 2017:

  1. Finish the network automation book.
  2. Launch an open source book project.
  3. Produce some video content.
  4. Get the Full Stack Journey podcast back on track.
  5. Complete a “wildcard project.”

So, how did I do with each of these projects?

  1. Finish the network automation book: I’m happy to report that all the content for the network automation book I’ve been writing with Jason Edelman and Matt Oswalt is done, and the book is currently in production (and should be available to order from O’Reilly very soon). I had hoped to get the content done in time for the book to be available for order before the Continue reading

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 ...
