You might be familiar with the idea of using BGP as an SDN tool that pushes forwarding entries into routing and forwarding tables of individual devices, allowing you to build hop-by-hop path across the network (more details in Packet Pushers podcast with Petr Lapukhov).
Researchers from University of Louvain, ETH Zürich and Princeton figured out how to use OSPF to get the same job done and called their approach Fibbing. For more details, listen to Episode 45 of Software Gone Wild podcast with Laurent Vanbever (one of the authors), visit the project web site, or download the source code.
Just in time for thanksgiving, Cisco has released version 1.0 of the popular network simulation tool VIRL. This is a major new release moving from Openstack Icehouse to Openstack Kilo. This means that your previous release of VIRL will NOT be upgradeable, only a fresh install is available. Cisco has started mailing out a link to the new release and I received my download link yesterday. It is also possible to download the image from the Salt server to the VM itself and then SCP it out from the VM, this is described in the release notes here.
The following platform reference VMs are included in this release:
There are also Linux container images included. These are the following:
This means that it will be a lot easier to do traffic generation, bandwidth testing and simulating a WAN by inserting delay, packet loss and jitter. It’s great to see Continue reading
An emergency switch replacement can ruin your day. However, having network config backups is not enough. Restoring full service may not be as easy as just copying the running configuration from your RANCID CVS repo, or your colleagues hard drive. Restoring the ‘identity’ … Continue reading

After DockerCon EU in Barcelona several people asked me: “Is this for real?”. Yes it is, and today we are releasing the code for the entire “Unikernels, meet Docker!” demo on GitHub.
To get started, clone the DockerConEU2015-demo repository and follow the instructions in README.md. You will need a Linux host with Docker and KVM installed.
Apart from the MySQL, Nginx and PHP with Nibbleblog unikernels shown in the demo, the repository also contains some simpler examples to get you started that we did not have time to show live in the short time-slot. There’s also an in-progress MirageOS/KVM port, so stay tuned for a future post on that.
Presented as a ‘cool hack’ in the closing session of the conference, this demo is just a taste of what is possible. Next, I’m going to work with the wider unikernel and Docker developer community on a production quality version of this demo. The goal is to make unikernel technology easily accessible to as many developers as possible!
Personally, I would like to thank Amir Chaudhry, Justin Cormack, Anil Madhavapeddy, Richard Mortier, Mindy Preston and Jeremy Yallop for helping me put the demo Continue reading
IT has been trained to operate equipment, but can they--and should they--learn the fundamentals that underpin the infrastructure? Does the enterprise have the skills, resources, and competency to handle the transition to the cloud? Check out this passionate debate.

By the time you read this, I’ll be down at Oak Island on the North Carolina Coast, where my wife will be getting the turkey ready, and making a white chocolate cheesecake. No, I won’t tell you the address, but I will tell you this.
I’m thankful for this year.
I’m thankful for my family. For my wife and kids who put up with me and my insane schedule.
I’m thankful for my friends (I would list them all, but I’d probably forget someone, which would hurt feelings; it just doesn’t seem right to hurt anyone’s feelings today). Across the years, I’ve been taught so much about networking and engineering in the last 20+ years, from working on RADAR systems to large scale data centers. I’ve been given so many opportunities to write and speak, and been shown how to be just a better person.
I’m thankful that God has opened a door into a top notch PhD program, the support structure every PhD student needs to succeed, and two great mentors (more than anyone could ask for).
I know it’s not Thanksgiving in every country in the world. But there’s never a bad day to give thanks for what Continue reading

Wow, another year swooshed by. I can’t believe it’s almost gone. Maybe it’s all the travels I had throughout the year, and I MUST start with a huge THANK YOU to whoever is watching after me – there wasn’t a single major SNAFU.
Next, I’d like to thank the people who caused all that travel: attendees of my workshops.

If you haven't heard what they actually did you'll hardly even believe it. That's this week's feature interview.
