Open≠Interoperable,why?
1. Access to Products
2. New Types of Interop Variables
4. Integration Resources Gap
3. Exponentially Larger Interop Matrix
Problem:AccesstoProducts(trytobuysome)
Solution:Getafewsamplestogetherinoneplace(sandbox)andmakeitavailabletoeveryone

4. Integration Resources Gap
2015• October 2015 Fidelity OCP EW Boston, MA • Launch Open Networking Integrators List10/40G Ethernet
2016• August 2016 UNH-IOL OCP EW Durham, NH • Add LR, LR-Lite Optics to Open Networking Integrators List• Add 100G to Open Networking Integrators List at NH OCP EW
2017
• March 2017 OCP US Summit Santa Clara, CA• Launch ONIETested.org• 100+ Configs on Open Networking Integrators List 💯• Launch UNH-IOL OSVS
