6WIND Virtual Accelerator® software provides a solution to power the hypervisor with the required features for virtual networking infrastructure used in Network Function Virtualization (NFV), Data Center Virtualization or Network Appliance Virtualization use cases. Popular use cases include uCPE and Software-defined Networking (SDN) virtual routing and switching solutions. It is deployed in the KVM hypervisor to offer a high performance alternative to SR-IOV and PCI passthrough that break virtualization.


  • A fully supported DPDK-based software data plane available since 2013
  • Line rate hypervisor networking
  • Accelerated virtual switching (Open vSwitch and Linux bridge) and networking (Overlays for multi-tenancy, L3 routing, VRF, ACLs, NAT, IPsec, QoS, TCP offloads and more)
  • Preserves standard Linux commands (tcpdump, iptables, IPsec/XFRM, etc.) for ease of deployment and operation
  • Supports standard network management tools including OpenStack and SDN controllers
  • Supports existing and unmodified workloads through standard Virtio drivers
  • Scalable software-based switching enables Service Chaining
  • No SR-IOV or PCI Passthrough
  • Increase VM density and performance on COTS servers
