Pica8 takes an open-source approach to the controller layer, by leveraging more than seven controller initiatives, including Ryu, Floodlight and NOX, and selecting a controller that best matches the customer's application needs.
Pica8's network operating system, PicOS, provides this functionality on top of commodity white-box bare metal switches. PicOS has OpenFlow 1.3 support, through Open vSwitch (OVS) v1.9 integration. OVS runs as a process within PicOS, and provides the OpenFlow interface for external programmability. It also exposes Debian Linux, so enterprises can use their existing tools for programming and optimizing Pica8 open switches to support their network.
