Accomplishments 1:
Advancing GENI Spiral 2 Goals
•
This work supports the Meso-scale deployment described in Section 7.4
•
Specifically, we are upgrading key parts of our infrastructure to give
researchers connectivity to OpenFlow-enabled switch ports.
•
At GEC8, we participated in the Aster*x demo from Stanford University.
Stanford researchers were able to use OpenFlow-connected resources at
Princeton as part of a multi-campus demonstration.

Issues
– Concern is the lack of long-term support and commitment to
OpenFlow by mainstream vendors.
• There is a great deal of interest in the vendor community
• However, we still don't see OpenFlow in deployed product offerings
– Current SNAC release only uses lower 48-bits of datapath ID.
Consequence is only one OpenFlow entity per HP switch managed
by a given instance of SNAC.
• Developers are aware and working the issue

Plans
•
What are you plans for the remainder of Spiral 2?
– Continue to support the Aster*x demo for GEC9
– Continue to deploy additional OpenFlow-capable switching in our production
infrastructure
– Continue to develop expertise in OpenFlow so we can migrate existing home-grown
tools to OpenFlow.
– Continue to grow number of users on our OpenFlow network.
•
The GPO is starting to formulate goals for Spiral 3. What are your thoughts
regarding potential Spiral 3 work?
– For us, Spiral 3 work will be a continuation of Spiral 2:
• Continued growth and deployment
