IoT’s payoff is in the big picture, and Nokia knows it

Large IoT systems usually have more than one job and need to work with other systems to be effective. Simplifying all this is one of the main things enterprise IoT platforms are designed to do.But it’s a moving target, so vendors need to keep adding new capabilities to their platforms. On Tuesday, Nokia announced updates to its Impact software platform to cover IoT applications including lighting, video analytics and parking management. There are also updates to accommodate new low-power networks.Impact is one of several software platforms designed to make IoT into more than a bunch of disparate sensor networks or automation systems. One application, like smart street lighting, may make another one, like connected parking meters, more effective. Data is the key, and integration can make all data more valuable.To read this article in full or to leave a comment, please click here

Amazon, Expedia tell US court Trump immigration order affects business

Amazon and Expedia have submitted declarations in a federal court in Washington, claiming that a recent immigration order by U.S. President Donald Trump is disrupting their business and affecting employees.The actions by these companies come amid widespread public protests against the order, with many tech companies prominently in the opposition.The declarations were filed by Amazon and Expedia in a lawsuit in which Washington State Attorney General Bob Ferguson has asked the court to invalidate parts of the executive order for a number of reasons including that it discriminates in the issuance of immigrant visas on the basis of race, nationality, place of birth, or place of residence.To read this article in full or to leave a comment, please click here

Why Are High-Speed Links Better than Port Channels or ECMP

I’m positive I’ve answered this question a dozen times in various blog posts and webinars, but it keeps coming back:

You always mention that high speed links are always better than parallel low speed links, for example 2 x 40GE is better than 8 x 10GE. What is the rationale behind this?

Here’s the N+1-th answer (hoping I’m being consistent):

Big Cloud Fabric Innovations for Hyper-converged, Containers and SDDC

Addressing 2016

Time for another annual roundup from the world of IP addresses. Let’s see what has changed in the past 12 months in addressing the Internet, and look at how IP address allocation information can inform us of the changing nature of the network itself.

Flokibot Invades PoS: Trouble in Brazil

Introduction Threat actors salivate at the thought of an increased volume of credit and debit card transactions flowing through endpoints they have compromised with card-stealing malware. While there are many distinct malware families that scrape unencrypted process memory to obtain cards, some of these malware capabilities overlap with generic information stealing trojans such as Flokibot […]

VRF Series Article 5 – Stateful Inter-Vrf connectivity

This is the fifth and final article in a series that focused on Segmenting Layer 3 Networks with VRFs. In the third article, we discussed creating a shared services VRF and using it within the otherwise segmented network. In that article I alluded to the fact that we would asav-1 later cover a way to securely allow traffic to flow between security zones. That is the intent of this article.

In this article, I am going to attach two sub interfaces between asav-1 and Main. One will attach into data and the other into pci. We will apply a simple policy that denies all traffic from data to pci, but allows telnet from pci to data (bad security example, but easy to demonstrate).

Before we jump into the configuration, I want to share the entire topology and give a summary of the current configuration status.

VRF_No_Int_Index

Current Configuration

In the above topology, anything that starts with “data” is in the data VRF. Likewise, anything that starts with “pci” is in the pci VRF. Everything within a given VRF can communicate with everything else in that same VRF. Both pci and data can communicate with the shared VRF (test IP address is Continue reading

Convince your manager to send you to DockerCon

Has it sunk in yet that DockerCon is in roughly 2 months? That’s right, this year we gather in April as a community and ecosystem in Austin, Texas for 3 days of deep learning and networking (with a side serving of Docker fun). DockerCon is the annual community and industry event for makers and operators of next generation distributed apps built with containers. If Docker is important to your daily workflow or your business, you and your team (reach out for group discounts) should attend this conference to stay up to date on the latest progress with the Docker platform and ecosystem.

Do you really want to go to DockerCon, but are having a hard time convincing your manager on pulling the trigger to send you? Have you already explained that sessions, training and hands-on exercises are definitely worth the financial investment and time away from your desk?

Well, fear not! We’ve put together a few more resources and reasons to help convince your manager that DockerCon 2017 on April 17-20, is an invaluable experience you need to attend.

Something for everyone

DockerCon is the best place to learn and share your experiences with the industry’s greatest minds and the guarantee Continue reading

Looking Ahead: My 2017 Projects

For the last few years, I’ve been sharing my list of projects for each year (here’s the list for 2012, the list for 2013, 2015’s list, and last year’s list—I didn’t do a list for 2014). Toward the end of each year, I also publish a “report card” assessing my performance against that year’s list (here’s the 2016 assessment). In this post, I’m going to share my list of planned projects for 2017.

Without further ado, here’s the list for 2017:

Finish the network automation book. One way or another, the network automation book I’m writing with Jason Edelman and Matt Oswalt is getting finished in 2017. (It’s available now as an Early Access edition if you’d like to give it a look and provide some feedback.)
Launch an open source book project. This is something I’ve been tossing around for a while now. Since my efforts at making code contributions to an open source project aren’t going so well (though I’m going to keep moving in that direction), I figured I’d contribute in a way I know I can do. This is going to be a “cookbook”-style book, and the goal I’m setting Continue reading

VRF Series Article 4 – VRF-lite in a DMVPN Network

As we’ve progressed through the Segmenting Layer 3 Networks with VRFs series, we have continued to build out a network that looks more like what we would see within an enterprise environment. This post takes it one step further and leverages the DMVPN (dynamic multipoint VPN) functionality to extend the network securely over the public DMVPN Internet. In the examples here, we actually go one step beyond a typical DMVPN and map VRFs to tunnels using the tunnel key. This allows the pci and data VRFs to maintain isolation across the VPN.

One more thing that we will do that isn’t related to the core requirement of segmenting pci from data is leveraging a F-VRF (or front side vrf) on the DMVPN routers to isolate the Internet facing interfaces that connect them to the public cloud. This is my preferred method for DMVPN deployment if I’m not doing split tunnelling (i.e. I am back-hauling all traffic to a central location).

As a prerequisite, I will go ahead and build out the Internet router and the interface on Main that connects to DMVPN-hub.

F5 Networks taps versatile Ciena higher-up to take over as CEO

F5 Networks CEO and President John McAdam, thrust back into that role in late 2015 under unusual circumstances, has announced that Ciena SVP and COO Francois Locoh-Donou will succeed him on April 3.McAdam joined F5 in 2000 and served as CEO and President until July 2015, when he handed the reins to Manuel Rivelo. But Rivelo stepped down in December of that year for unspecified personal conduct issues, and McAdam jumped back into the fray at the Seattle company, which he has helped to build into an application delivery powerhouse generating about $2B in annual revenue.
