PLVision’s engineers have enabled support of Intel DPDK for Ostinato – an open source and cross-platform traffic generator.

DPDK is a user-space software library that provides considerable speed improvements via:

  • Avoiding latency caused by copying through kernel space
  • Replacing interrupts with polling
  • Using HW-optimized features (batch mode, SSE, NUMA).

Having preserved full functionality of Ostinato in this implementation, we have been able to achieve the following traffic improvements:

  • 10G full rate TX on any packet size
  • 10G full rate TX/RX on packet size starting from 128B
  • 10G full rate RX/Capture on packet size starting from 256B.
