Corsa Technology offers a full, OpenFlow programmable data plane
that delivers performance, flexibility, and scale.

The first use case for SDN-based metering and QoS involves large data set transfers, such as between major research facilities and super computer labs. Corsa's demo uses OpenFlow 1.3.
Presented by Bruce Gregory, David Whittaker, and Carolyn Raab.
