It is now a ready-to-use Debian-based distribution that makes use of the Data Plane Development Kit (DPDK) libraries to provide highly efficient software packet-processing on x86 hardware , and in addition to Broadcom’s Open Network Switch Layer (OpenNSL) libraries to support a hardware programming plugin architecture for merchant silicon based forwarding. An example OpenNSL plugin for the UFiSpace S9500-30xs device is provided.
