6WIND Virtual Accelerator® is a host network acceleration software that provides a solution to power the virtual networking infrastructure with the required features, performance and scalability. Used in Network Function Virtualization infrastructure (NFVi), Data Center Virtualization or Network Appliance Virtualization use cases. It’s based on 6WIND core technology (6WNOS).
Features
Mature solution for high performance I/O leveraging DPDK, with multi-vendor NIC support
Accelerated virtual switching (Open vSwitch and Linux bridge) and networking (Overlays, Filtering/NAT, IP Forwarding, IPsec) using the fastest packet processing algorithms
Ease of deployment and operation
Preserves standard Linux commands (tcpdump, iptables, IPsec/XFRM, etc.) for ease of deployment and operations
Supports standard network management tools (OpenStack and SDN controllers)
Supports existing workloads through standard Virtio drivers
Scalable software-based switching enables Service Chaining
High virtualization performance without SR-IOV
Advanced monitoring through streaming telemetry with time series data base and graphical analytics
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.
6WIND Virtual Accelerator provides efficient switching to increase virtual infrastructure performance.
Testing in live OpenStack environments shows most Virtual Network Functions (VNFs) can achieve performance boosts of up to 5x and 20 Gbps throughput without SR-IOV or any changes to the VNF.
By offloading network packet processing to dedicated CPU cores, 6WIND Virtual Accelerator maximizes the number of Virtual Machines (VMs) without affecting individual networking performance requirements. The increased VM density can be applied to additional VNFs such as load balancers, firewalls, etc. to generate new revenue streams on existing servers.
