Carp branch released

November 12, 2013 in News, POX

A few weeks ago, a new development branch appeared: dart. When this happens, it generally means that the previous branch is moving to release, and there should be an announcement and so on. I’ve been intending to do all that, but haven’t gotten around to it, so instead… you just get this quick notice. :) Maybe I’ll find time to come back and extend it later, but the highlights are that carp is now the default branch and new development is going into dart. This reflects the fact that new projects are quite probably best served by starting from there rather than its predecessor (betta). Hope everyone finds this to be true!

POX and Gephi graph streaming / visualization

June 2, 2013 in News, POX

POX has an unsupported visualization GUI in the form of POXDesk, but today it got another somewhat different option. Gephi is a great (open source) graph visualization and manipulation package. It has a plugin for streaming graphs in and out over HTTP, and POX’s new misc.gephi_topo component uses this to stream switches, links, and (optionally) hosts to it. Once the graph is in Gephi, you can export it to graph file formats, analyze it in a bunch of different ways, just look at it, render it as SVG, and so on. Read on for more info and a screenshot.

POX as an OpenFlow Switch

June 1, 2013 in News, POX

POX is now an OpenFlow switch as well as an OpenFlow controller. Most of the code for this has actually been in the repository for a while and has been used along with the STS SDN Troubleshooting Simulator, but we’ve never had all the pieces assembled in the repository to actually let you run POX as a standalone switch until now. It’s definitely not the best switch, but it might do in a pinch and someone may find some use for it. We’re hoping to improve its spec conformance some in the next couple of weeks. As for performance… I wouldn’t hold your breath for big improvements. :)

New POX branch: carp

May 20, 2013 in News, POX

A little while back, POX’s betta branch was unceremoniously made a release branch and became the default when cloning POX. This was a reflection of the decision that you were strictly better off using betta than its predecessor (angler). This also meant it was time to create a new branch for active development — that branch is carp.

NOXRepo Web Forums

February 13, 2013 in News

The nox-dev mailing list was one of the first places on the net to discuss OpenFlow and SDN issues. Since then, we’ve added other ways to contact us and engage the community. For example, the pox-dev mailing list, the github Issues system, and comments on We’ve just added another on a sort of trial basis: web forums.

This week, POX’s betta branch gained a simple DHCP server. I’m actually aware of at least three other POX DHCP servers(!), but this is the first one in the mainline. It’s pretty bare-bones, but it might Do The Job for you (and if it doesn’t maybe it’s at least a start). It also demonstrates a rarely seen POX feature: multiple launch functions.

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.

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.
