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.
Service chaining is an emerging set of technologies to enable telecom service providers to configure virtualized telecom services that are currently being carried out by proprietary software and hardware. Currently, service chaining requires better methods are required to improve resilience and availability of service chains. Learn about two proof-of-concept demos to address the technology gaps.
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...
Many POCs focus on maximizing network throughput, but an equally important performance metric is latency. The authors used a testbed devised to characterize the performance of a virtual Customer Premises Equipment setup, based on the Intel® Open Network Platform architecture with the Data Plane Development Kit. Testing highlighted significant performance improvements in terms of reduction of...
Learn how to configure jumbo frame support for DPDK-enabled ports on an Open vSwitch* (OvS) bridge and also how memory management for jumbo frames works.
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.
