High performance computing is essential for NFV applications.
This article walks you through configuration of OVS with DPDK for inter-VM application use cases. Create an OVS vSwitch bridge with two DPDK vhost-user ports, each connected to a separate VM, then use a simple iperf3 throughput test to evaluate performance.
The networking world is rife with buzz words like SDN, NFVs, Cloud, and Virtualized everything for network switches, routers, firewalls, load balancers, web servers, and other communication functions. Commodity NICs can replace expensive, specialized hardware devices for much less cost and can easily be reconfigured as requirements change. When you are ready for SDN/NFV, where to start, what to...
This article steps you through getting started with the Data Plane Development Kit (DPDK), including building and testing a sample application, l2fwd. It then introduces you to the Data Plane Performance Demonstrator.
This article shows how to configure Intel® Ethernet Flow Director, which can direct Ethernet packets to the core where the packet consuming process is running.
When running in a virtual machine, you may never be sure which physical CPU you are running on - hypervisor can pass anything as CPUID to guests. For best performance, it helps to use the best instruction set supported by a physical CPU - be it AVX512, AVX2, AVX, SSE4.1, AES-NI, or other accelerated instruction sets. Enhanced Platform Awareness features use top-down approach to close this gap,...
To realize the benefits of virtual radio access networks (vRAN), general purpose processors must handle signal processing effectively.
Yardstick NSB is a test framework for measuring VNF performance in an NFV environment or an NFV infrastructure. It runs on native Linux* (bare metal), standalone virtualized, and managed virtualization. This tutorial details how to install Yardstick NSB on bare metal.
