Accelerate containers and VMs networking with vDPA - DevConf.CZ 2020
Channel: DevConf
Date: 30/03/2020

Speakers: Maxime Coquelin, Ariel Adam

In this talk we will be introducing vDPA (virtual datapath acceleration) and full virtio HW offloading intended on providing wirespeed/wirelatency L2 interface to containers and VMs. Such interfaces are desired for NFV use cases (VNFs/CNFs) and for enterprise use cases as well.
What makes these interfaces unique compared to existing technologies (such as SRIOV) is that they are based on open standards and open source projects leveraging new smart NICs being developed by major vendors and offloading virtio devices to the HW itself (data and control planes). This decouples the VM/pod running from the NIC being used, which provides a number of major advantages we will be talking about.
We will be covering the building blocks used to implement the Virtio path in the host (kernel/DPDK) and on the consuming app (using DPDK pmds).
We will conclude by presenting the architecture used for providing vDPA interfaces to containers in K8s as a Multus secondary interface and present a live demo.
