Switch Light™ is a Linux-based, thin switching software solution, providing consistent data plane programming abstractions across merchant silicon-based physical switches (white-box or brite-box) and hypervisor vSwitches.
Switch Light is a key enabling technology for Big Switch Networks’ centralized SDN applications, and comes in two flavors:
Together, the Switch Light OS and Switch Light VX enable next generation networking fabrics. In conjunction with a centralized SDN controller, Switch Light enables dramatic reductions in the cost of your network operations and eliminates time-consuming, manual procedures by enabling central provisioning, automation and troubleshooting of both switching platforms and service definitions. Switch Light OS or Switch Light VX are available only as a part the Big Switch Network product portfolio including Big Cloud Fabric and Big Monitoring Fabric.
By leveraging the industry standard Open Network Install Environment (ONIE) and ONL, and a hardware compatibility list shared across the white box switching ecosystem, Switch Light is designed with migration in mind. On startup, a user can opt to boot up either the Switch Light OS, traditional networking OSs from other vendors or a hardware diagnostic OS. There are no hardware or cabling changes required to go between controller-based and traditional box-by-box networking designs -- a simple, low-risk migration path to SDN.
