24. Fall 2006 I2 Member Meeting Conclusions

25. Fall 2006 I2 Member Meeting A Book written by the Community Published!

26. Fall 2006 I2 Member Meeting Conclusions Control Plane research is vital to meeting future generation Grid computing - with a strong focus on algorithms to meet the needs of driving applications. Simplifying Control of Global network resources in coordination with compute relevant resources (clusters, data store, instruments, etc.) is critical to next generation Scientific and Enterprise advancements. The Research networks ( w/ exception to Japan’s Carriers) are the ones taking bold steps w/ control plane deployments, testbed infrastructures… Continue to foster collaboration and apply lessons learned to production quickly. International Collaboration is a very Key ingredient for the future of Scientific discovery - The control of Optical network plays the most critical role in achieving this!
