- 5. Networking Hardware is a Commodity Broadcom dominates the silicon market (think Intel x86) • Currently used by all major ToR switches OEM Manufacturers build systems based on Broadcom design • OEMs have a roadmap of upcoming systems • In many cases, Brand vendors pick existing design and only add their software • Switches are internally virtually identical CONFIDENTIAL 6

- 16. OpenFlow Model 17 SDN Controller Features/Apps Controller Platform Networking Silicon Network OS SDN Client SDN Protocol (e.g. OpenFlow) Vendor B • Controller Platform • Applications on Top Vendor A • Build Feature Switch • Adds OpenFlow Client SDN Enabled Switch Customer • Picks Controller • Picks Switch • Best-of-breed • Innovation now can happen! Who can name an example of a production deployment that follows this model?
- 17. OpenFlow Deployments Today • SDN is doing extremely well – ONS with 1,600 attendees – NSX at $200m run rate, 400 customers – BSN had $1m in pre-orders for it’s Cloud Fabric – Analyst predictions are going up… • Why is no one following the original model?
- 18. OpenFlow Development The original model constrains innovation New Chip Feature under NDA 1 year OpenFlow 1.X Standard dev 1 year Vendors implement OF 1.X on Switch 1.5 years Controller Development 1 years 4.5 years Networking industry is moving very quickly Standards-based development model slows down innovation.
