Use the Data Plane Development Kit with Open vSwitch* to Create vHost User Non-Uniform Memory Access AwarenessLearn about the concept of vHost User non-uniform memory access (NUMA) awareness, how it can be tested, and the benefits the feature brings to Open vSwitch* (OvS) with the Data Plane Development Kit (DPDK).
This article describes the concept of Data Plane Development Kit (DPDK) pdump, how it can be tested, and the benefits the feature brings to Open vSwitch* (OvS) with DPDK. OvS users will learn how to monitor traffic on DPDK devices in their setup.
vHost User client mode addresses a limitation in the DPDK, whereby if the vHost User backend crashes or is restarted, virtual machines with DPDK vHost User ports cannot re-establish connectivity and are essentially rendered useless from a networking perspective. vHost User client mode solves this problem.
This tutorial describes how to set up a demonstration or test cluster for Open vSwitch* (OvS) and Data Plane Development Kit (DPDK) to run together on OpenStack*, using DevStack* as the deployment tool and the Neutron ML2/GRE Tunnel plugin.
