Link™ Virtualization Software
for Napatech FPGA-based SmartNICs
Napatech SmartNICs and Link™ Virtualization Software provide a hardware-based solution for OVS offload, dramatically increasing performance while reducing CPU consumption. The Link™ Virtualization Software offloads and accelerates the Open vSwitch (OVS) dataplane to provide increased network performance and much better CPU efficiency with lower complexity and enhanced scalability than alternatives.
Link™ Virtualization Software supports a broad range of applications and use cases – and can immediately improve an organization’s ability to monetize virtualized applications.

Network operators are using virtualized solutions in their network architectures based on open and standard computing platforms, offering the ability to optimize equipment costs and operational expenses by deploying services as software.
For virtualized application hosting, Open vSwitch (OVS) is the default multilayer switching solution. But software-based virtual switching requires significant CPU resources, resulting in low data throughput and wasting valuable CPU cycles.
Napatech’s Link™ Virtualization Software and FPGA-based SmartNICs offer a 60x performance improvement compared to alternative approaches and saves significant CPU resources.

Link™ Virtualization Performance Demo
Napatech’s hardware-based OVS offload solution offers a 6X gain compared to OVS DPDK and 60X gain compared to OVS kernel in performance, while reducing the CPU cycle consumption by as much as 90% compared to alternatives. While kernel based or user space (DPDK) versions of OVS are incredibly CPU intensive with network intensive workloads, Napatech’s SmartNICs and Virtualization software accelerate OVS and provide much better CPU efficiency, lower complexity, enhanced scalability and increased network performance.
Tested with 64byte frames, 1024 megaflows, 8 million individual flows.
For virtualized application hosting, OVS is the default solution for demultiplexing traffic from the network to, from, and between applications running in VMs or containers. Software-only implementations of OVS, though, fail to meet the performance and scale requirements of virtualized applications. Additionally, running OVS in software, which is the standard practice, uses significant CPU resources simply for directing traffic, stealing those CPU resources from revenue generating applications.
Custom Workload Acceleration
Data processing workloads, like encryption, regular expression matching and compression, can be extremely compute intensive when performed in software and require a tremendous amount of CPU cores. By offloading these functions to accelerated SmartNICs, it is possible to significantly increase the workload performance and free CPU cores to support more virtualized applications on the same server.
Napatech’s hardware offload solution utilizes the SmartNIC programmability to allow custom workloads to be implemented in an inline or look-aside model.

VM-to-VM Monitoring provides insight into both North-South and East-West data in virtualized servers without consuming CPU cores.
Napatech’s VM-to-VM monitoring solution can replicate traffic in hardware based in specific ports or flow-based rules and send the mirrored traffic to either another VM or an external analytics solution.
