Building real world datacenter networks using OpenFlow white box switches

For this event we will be hosting David Liu, Chief Architect of Pica8

About David Liu

David Liu, Chief Architect at Pica8, brings an extensive software and service provider background to the discussion. Before Pica8, David held software management positions with Cortina Systems, Ericsson and Lantern Communications. He holds a MS in Computer Science from University of Michigan.


White box switches are emerging as a viable alternative for network architects deploying software defined networks, but SDN deployments will require OpenFlow support. In this presentation, David will explain the experience of taking an OpenFlow white box switch to production in 3 data centers. The presentation will cover the following topics:

- How to work through limited TCAM in commercial silicon and maximize the TCAM usage for production

- How to scale an OpenFlow-based data center network under constraints

- How commercial silicon supports the OpenFlow 1.3 specification

- Additional features of the OpenFlow specification that will drive commercial silicon development

- Interworking L2/L3 and an OpenFlow network on the same switch

      Tejas, do you mean meetup page or specific company page, please? In case it's meetup, I was unable to locate that page. Grateful for your assistance.

    David, Looking forward to your talk on the production environment this time. The last time you did a presentation for us was an immersive hands-on which was very helpful to our audience!!

    Vikram, Thank you for inviting me. Just like to share the scale of the OpenFlow network to be in production next month. It has 3 data centers, each one has 12 racks with ToR, EoR, and Border (Inter DC) switches in a hierarchical configuration, but only runs OpenFlow 1.3. David
