DPDK vHost User Improvements and Their Benefit to the DPDK Datapath in OVS- Ciara Loftus, Intel

Sign up or log in to save this to your schedule and see who's attending!

DPDK libraries accelerate packet processing in Open vSwitch for both physical and virtual interfaces. vHost User is the defacto standard virtual interface accelerated by DPDK that provides a high bandwidth path to VMs and VNFs for NFV use cases. This presentation will describe the many new vHost User features that are available in DPDK today and that OVS leverages in order to provide a feature-rich accelerated virtual interface for NFV.
After a brief introduction to the vHost User standard, the most recent developments in the standard will be described. Several new features have been integrated into OVS in the last year, including vHost User NUMA-Awareness, vHost User client-mode and vHost User reconnect. An overview of each of these features will be presented, along with the associated performance improvements from both the typical throughput perspective as well as the functional perspective.
To conclude, some of the future improvements will be discussed, including the vHost PMD and the virtio-user concept. Finally some discussion on general performance enhancements that are in development which aim for DPDK vHost User to reach the maximum achievable performance with the existing vHost User standard.
