What's new in CloudNetEngine vSwitch 2.1

  • Pure polling RX mode to improve NFV workloads performance further. (CNE vSwitch uses interrupt + poll hybrid RX mode by default)
  • A new scheduling policy for RXQ NUMA strong affinity.
  • Performance improvement on large scale concurrent flows.
  • Upgrade control/management front end to OVS 2.8.2.

vSwitch performance comparison


For NFV workloads, CNE vSwitch 2.1 can get 20~50% higher throughput than OVS-DPDK under various packet size and number of concurrent flows.



For Enterprise workload, CNE vSwitch 2.1 saves around 50% CPU cycles and get 10~20% higher throughput comparing to Native OVS.
