This article explores the internal details of provisioning a physical machine using OpenStack*. Steps for setting up OpenStack are included, and no special hardware is required to begin use.
Enhanced Platform Awareness (EPA) relies on a set of OpenStack Nova* features called Host Aggregates and Availability Zones. The Nova scheduler uses these objects to determine which host a guest should be launched on based on the capabilities of the host and the requested features of the virtual machine (VM). This article demonstrate how EPA can be used by the operator in OpenStack deployments...
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.
This article presents a firewall for OpenStack’s Neutron project that is based entirely on Open vSwitch rules. The firewall is based on "learn action" and uses the same public API to talk to the Neutron agent as the existing Linux Bridge firewall implementation, making it a straight swap for people already using OVS.
Network Function Virtualization (NFV) replaces existing networking appliances such as routers and switches, with virtualized, software-based implementations of these appliances running on standard high-volume servers (also known as Virtual Network Functions (VNFs)). By leveraging NFV, ISPs can provide a virtual Customer Premises Equipment (vCPE) solution to reduce their overall operating and...
Get an overview of OvS-DPDK—the high performance, open source virtual switch. Dive deeper into individual OvS-DPDK features with links to related technical articles and tutorials.
The Data Plane Development Kit (DPDK) packet capture framework consists of the DPDK pdump library and DPDK pdump tool. The article describes how the feature works and shows how to set up traffic monitoring on DPDK-controlled devices.
Learn, review, or get started with DPDK. This article contains links to all session videos and slides presented at Intel Developer Zone DPDK/NFV July 2016 Devlab.
Describes the design and implementation of the datapath classifier – aka dpcls – in Open vSwitch* (OVS) with Data Plane Development Kit (DPDK). It presents flow classification and the caching techniques, and also provides greater insight on functional details with different scenarios.
Configure the DPDK link aggregation feature. Link aggregation combines multiple network connections in parallel to increase throughput beyond what a single connection could sustain.
