I’m hopeful of this white box approach to networking but cautiously optimistic. It would be great to put opensource software of openswitch like software on white box devices. While not SDN or Openflow directly it does give a great deal more capability to SDN type implementations. As the interface into the hardware layer is open and standard.
My reservation is the ability to innovate at the hardware layer at the same pace you can now with proprietary operating systems. Who’s going to invest in make a white box fabric that will compete with Cisco, Juniper and Arista? Top of the rack is a start but ultimately we’d like to see this in the core as well. I have a difficult time seeing open compete at the entire data center fabric level. I’m hopeful however that it will.
