Welcome!

NOXRepo.org is the home of two Open Source control platforms for Software Defined Networks.


NOX is the original OpenFlow controller, and facilitates development of fast C++ controllers on Linux.

(There's also NOX Classic which supports both C++ and Python. We have no plans to do substantial further development on this project, but don't let that stop you from using it if you think it fits your needs best.)

POX is great for diving into SDN using Python on Windows, Mac OS, or Linux -- you can be controlling OpenFlow switches only seconds after downloading it. It's targeted largely at research and education, and we use it for ongoing work on defining key abstractions and techniques for controller design.

You can check out the resources in the menus in the upper right, dive straight into the code on github, read more about NOXRepo.org, or just check out the news and articles below.


The mailing lists aren’t dead!

October 5, 2012 in News

The Google group archives of the mailing lists (or at least the pox-dev one) apparently died a while ago, and I haven’t taken/had time to fix them.  But the lists are actually still active.  I thought I should point this out in case people have been discouraged from joining the lists because they seemed to be dead.  I’ll try to fix the archives at some point, and sorry for the confusion and inconvenience.

New POX branch: betta

September 19, 2012 in News, POX

Today, POX gets its second branch: betta. It’s named after the genus of fish, perhaps the most well known member of which is the rather pretty Betta splendens. This branch is based off my fork which has been slowly accumulating changes for a while now.

POX Web Interfaces

September 12, 2012 in POX

NOX-Classic has had a Qt based GUI for quite a while now, and in slightly modified form, it made it into POX as well.  However, I do hear requests for a web-based GUI from time to time.  I’d like to briefly discuss three relevant items: my own extensible web-based GUI for POX (POXDesk), POX-based JSON-RPC webservices, and Sam Russell’s work using POX with Django.  And if you’re not that interested in the technology behind it, I’ll post some pretty pictures too.

RouteFlow keeps flowing forward

August 1, 2012 in News, NOX, POX, ThirdParty

Congratulations to the RouteFlow team, who announced another update to RouteFlow today! This follows the really big update from earlier this year, which was possibly the first multi-controller SDN application — it utilizes both NOX and POX.

NOX Reference Posted

Just wanted to post a note that we’ve put the doxygen for the new NOX up on the web. You can find a link on the documentation page.

Pocket POX: Taking your OpenFlow controller with you

July 27, 2012 in POX

One of the goals for POX is to have it be easy to get up and running. This fits well with some of its broader goals (e.g., for use in education), and I am sure many people will attest is in contrast to NOX (especially before NOX verity). One of the things that falls out is that it’s pretty easy to get running almost anywhere. I’ve already shown it running on the BeOS-inspired Haiku OS. And while that’s cool, not a whole lot of us have a machine running Haiku. On the other hand, a whole lot of us have smartphones. So sure, why not run POX on one? That way we can all be assured of never getting into that embarassing situation when you’re at a party and everyone else brought an OpenFlow controller except you.

NOX-Classic on github

July 20, 2012 in NOX

As of today, NOX-Classic — the NOX you’ve known since 2009 — is up on github. Sorry this took so long, but it’s done now!

Stanford team wins the Imagine App Challenge… with POX!

The Cable Show is a giant convention put together by the National Cable & Telecommunications Association, which covers content, technology, and future directions for the cable industry. This year, it was toward the end of May in Boston, and included a hackathon.

POX Installation Video

May 7, 2012 in POX, Tips

Brent Salisbury, the author of the Network Static blog, recently posted a YouTube video showing how to get POX up and running on Ubuntu. I wanted to give out a shout of thanks for that, and throw in another little tip or two.

OpenFlow Wireshark Dissector on Windows

March 30, 2012 in Tips, Windows

The OpenFlow Wireshark dissector is part of the OpenFlow reference implementation, and is really a useful tool. Like the rest of the reference implementation, however, it’s really geared at Linux. But one of the goals of POX and — by extension — NOXRepo is to make SDN a bit more accessible, and this motivates getting Mac OS and Windows in on the action too. This led to me writing a post a few weeks ago describing how I built the dissector on Mac OS. Urged on by a post on nox-dev, I thought I’d write up how you can build it on Windows too. (And, again: prebuilt binaries for the impatient :).)
