Period: 1Q11

I. Major accomplishments

OpenFlow support in PEN experiments.

A. Milestones achieved

Gave a demo and a tutorial at GEC10.

B. Deliverables made

• OpenFlow enabled OpenVZ containers
• GEC10 tutorial web site
• GEC10 tutorial handouts

II. Description of work performed during last quarter

A. Activities and findings

In order to achieve OpenFlow support we had to modify the approach to interface allocation within the host PEN image. By default interface allocation predominantly utilizes virtual interfaces and bridging. Unfortunately, the Linux Bridge is incompatible with OpenFlow. The new approach adjusts the scripts to assign VLAN tagged interfaces directly to virtual containers. This enables virtual containers which can be utilized as OpenFlow switches.
