Floodlight OpenFlow Controller GUI Applet
There is a new FloodLight OpenFlow SDN controller GUI out from a Marist College and IBM research group/internship. I am guessing it is the same IBM researcher that developed the FloodLight web UI. This applet allows one to instantiate a flow from the GUI along with a couple of other bells and whistles. It is great to see the public/private …
How to Build an SDN Lab without Needing OpenFlow Hardware
How do you build a networking lab without networking equipment? Yet another plus in the column of open software driven networks.

Configuring VXLAN and GRE Tunnels on OpenvSwitch
I have done a couple of GRE tunnel how-tos using OpenvSwitch (OVS). I had been itching to give VXLan a spin in OVS so why not ferret out someones tree on GitHub. I believe VXLan is still scheduled to officially release soon in OpenvSwitch. So here are the steps for installing, configuring tunnels on OpenvSwitch with VXLan and GRE encapsulations. …

OpenvSwitch Configure from Packages and Attaching to a Floodlight OpenFlow Controller
OpenvSwitch Configure from Packages and Attaching to a Floodlight OpenFlow Controller: Couple folks have asked about installing OpenvSwitch from packages on Ubuntu 12.04 as opposed to from source. The default repos have v1.4 up so almost at the latest v1.4.1. OVS will be the de facto vSwitch in the hyper-scale providers in the future in my opinion. As Vmware’s Nicira acquisition …
MPLS VPLS configuration with Juniper JunOS
Posting a Juniper VPLS how-to on a couple of J-series routers. Have been pretty SDN focused lately so wanted to get some real stuff in for a post. Docs on JunOS VPLS can be shaky so nothing like a couple real configs to plugin your address in the lab if having problems with L2 VPNs. This includes MPLS VPLS configuration …
OpenStack Essex and Quantum Installation using OpenvSwitch from Scratch
Here is a walkthrough for the Quantum Network Manager Plugin for OpenStack Essex with a Quantum Installation with OpenvSwitch. It is still in dev so expect weird things and stability issues. For a guy with a networking bread and butter this is the extremely exciting piece of OpenStack for me. I will do a followup and try and breakdown the OpenvSwitch …
