Next Generation SDN Interfaces

Enabling full lifecycle control and automated network management

  • Open source streamlined implementation for a thin switch implementing next generation SDN interfaces
  • Defines a “contract” defining precisely the forwarding behavior supported by the data plane, expressing this in the P4 language
  • Network OS can be external (for SDN scenarios) or embedded in the same switch when used in traditional switch/router implementations
