A. Activities and findings

The University of Wisconsin-Madison recently launched WISDOM (the Wisconsin Institute on Software-defined Datacenters in Madison). This initiative brings together faculty and students from networking, systems, and security to address the challenges and opportunities of software-defined data centers, which form the core of the future cloud platform. Several projects have been spawned under this initiative which rely on the UW-Madison OpenFlow testbed for prototyping and evaluation. The projects include: software-defined interfaces for layer 3-7 network services, efficient scaling and load balancing of layer 3-7 network services deployed in clouds, development of distributed denial of service and anomaly detection frameworks for software-defined networks, integration of software-defined storage (SDS) and software-defined networking (SDN), and several others.

To support these projects, we have reconfigured our network in a small data-center-like tree topology, and we are in the process of deploying software-defined switching and virtualization software on these nodes to provide a more cloud-like environment for experimentation. We are also in the process of acquiring more servers and switches to double the size of the topology and include higher-bandwidth 10Gbps links between our aggregation and core layers. Once we gain more experience in managing and experimenting in the testbed, we hope to make it available to external experiementers to support their work on clouds and data centers.

D. Outreach activities

We have established an SDN Development Group at UW-Madison to train both graduate and undergraduate students how to design and implement a variety of SDN applications. We started by having the participants work through the OpenFlow tutorial, using our GENI infrastructure to test their applications. Currently, the students are working on a variety of individual and group projects to further expand their SDN development skills.
