Machine Learning and Network Traffic Management
A while ago Russ White (answering a reader question) mentioned some areas where we might find machine learning useful in networking:
If we are talking about the overlay, or traffic engineering, or even quality of service, I think we will see a rising trend towards using machine learning in network environments to help solve those problems. I am not convinced machine learning can solve these problems, in the sense of leaving humans out of the loop, but humans could set the parameters up, let the neural network learn the flows, and then let the machine adjust things over time. I tend to think this kind of work will be pretty narrow for a long time to come.
Guess what: as fancy as it sounds, we don’t need machine learning to solve those problems.

I gave a presentation at the recent Network Field Day 17 (on my 3rd day working for Juniper). My main goal for this presentation was just to get people excited about building stuff. We tend to focus on vendor-provided solutions in this industry, and there’s a lot of good reasons for that, but it’s also good to stay sharp and be able to build your own solution to fill gaps where necessary.Intentional Infrastructure

We tend to focus on vendor-provided solutions in this industry, and there’s a lot of good reasons for that, but it’s also good to stay sharp and be able to build your own solution to fill gaps where necessary. One reason I joined Juniper is that much of what we offer is built on a highly programmable foundation. So you get the best of both worlds - high-level products to solve the hard problems, but you still have the ability to insert your own custom tooling at various points in the stack.
In the above video, I outlined a simple Github-available demo for applying policies to a vSRX based on the existing services running in Kubernetes, and then verifying those policies are actually working by again using Kubernetes to determine what applications should be available.
My demo is designed to be self-sufficient, meaning you should be able to follow the README and get a working demo. Feel free to watch the above video first for context, then Continue reading

Blame privacy activists for the Memo??
Former FBI agent Asha Rangappa @AshaRangappa_ has a smart post debunking the Nunes Memo, then takes it all back again with an op-ed on the NYTimes blaming us privacy activists. She presents an obviously false narrative that the FBI and FISA courts are above suspicion.I know from first hand experience the FBI is corrupt. In 2007, they threatened me, trying to get me to cancel a talk that revealed security vulnerabilities in a large corporation's product. Such abuses occur because there is no transparency and oversight. FBI agents write down our conversation in their little notebooks instead of recording it, so that they can control the narrative of what happened, presenting their version of the converstion (leaving out the threats). In this day and age of recording devices, this is indefensible.
She writes "I know firsthand that it’s difficult to get a FISA warrant". Yes, the process was difficult for her, an underling, to get a FISA warrant. The process is different when a leader tries to do the same thing.
I know this first hand having casually worked as an outsider with intelligence agencies. I saw two processes in place: one for the flunkies, and Continue reading
Top 5 moments from Networking Field Day 2017
Did you miss Cumulus Networks’ session at Networking Field Day 2017 on February 26th? Or maybe you tuned in, and you want to reminisce on the best moments? Don’t worry, we’ve got you covered! Check out our top five favorite highlights from Technical Marketing Engineer Pete Lumbis’ presentation about managing EVPN/VXLAN. (You can also watch the whole session here, if you’d prefer to hear it from the man himself. Prepare for an intelligent demonstration peppered with some good laughs!)
5) The Legos of Linux
It makes sense to start with the basics, and that’s exactly how we begin the presentation. In a daring move, Pete decides to illustrate Cumulus Linux’s capabilities sans-Powerpoint, and whiteboards the architecture of a Mellanox switch running our OS.
One of the great things about Cumulus technology is that it’s all based in Linux. So, any configurations you would make on a Linux device are exactly the same on Cumulus Linux. Simple, right? That’s exactly our goal — allowing customers to easily customize their network as they see fit with basic building blocks. As Pete describes it, building the network is like “taking those Lego pieces and turning them into Saturn V.” Continue reading
What It Takes to Build a Quantum Computing Startup
If you thought the up-front costs and risks were high for a silicon startup, consider the economics of building a full-stack quantum computing company from the ground-up—and at a time when the applications are described in terms of their potential and the algorithms still in primitive stages.
Quantum computing company, D-Wave managed to bootstrap its annealing-based approach and secure early big name customers with a total of $200 million over the years but as we have seen with a range of use cases, they have been able to put at least some funds back in investor pockets with system sales …

Up and Running with oVirt 4.2 and Gluster Storage
In December, the oVirt Project shipped version 4.2 of its open source virtualization management system. With a new release comes an update to this howto for running oVirt together with Gluster storage using a trio of servers to provide for the system's virtualization and storage needs, in a configuration that allows you to take one of the three hosts down at a time without disrupting your running VMs.
If you're looking instead for a simpler, single-machine option for trying out oVirt, your best bet is the oVirt Live ISO page. This is a LiveCD image that you can burn onto a blank CD or copy onto a USB stick to boot from and run oVirt. This is probably the fastest way to get up and running, but once you're up, this is definitely a low-performance option, and not suitable for extended use or expansion.
Read on to learn about my favorite way of running oVirt.
oVirt, Glusterized
Prerequisites
Hardware: You’ll need three machines with 16GB or more of RAM and processors with hardware virtualization extensions. Physical machines are best, but you can test oVirt using nested KVM as well. I've written this howto using VMs running on my "real" Continue reading

A Behind the Scenes Look at Mobile Ad Fraud
How did I use over a gigabyte of mobile data in a single day? Why is my phone as warm as a hot plate? If you have ever asked yourself either of these questions, you might be the victim of a malicious application that is using your device and consuming your mobile bandwidth to facilitate ad fraud. We have recently identified a large population of apps being distributed from the Google Play Store that support this behavior. These apps are installed on devices on a majority of the major cell phone carriers around the world. These carriers operate in the US (AT&T, Verizon, Sprint, and T-Mobile), Europe (KPN, Vodafone, Ziggo, Sky, Virgin, Talk Talk, BT, O2, and T-Mobile), and the Asia Pacific region (Optus, Telstra, iinet, and others) [Note: Mobile providers and Google have been notified]. Just this morning, before this article was published, Buzzfeed broke another ad fraud story.
