This event was held in Club Auto Sport, San Jose.

+ +
    +
  • +

    Opening Remarks & Governing Board

    +

    Introduction to the event, including a review of the agenda, logistics and expectations. An update from the Governing Board on who the Governing Board are, what their responsibilities are, progress to date, future priorities/challenges for the project.

    Community Survey Feedback

    +

    We conducted a survey of the DPDK community, soliciting input on a variety of topics including DPDK usage, roadmap, performance, patch submission process, documentation and tools. This session will present the results of the survey, which will help to guide the future direction of the project.

    Reducing Barriers to Adoption - Making DPDK Easier to Integrate into Your Application

    +

    While DPDK is a widely-adopted software package for high-performance networking applications, there are a number of ways in which it is harder to use than it otherwise needs to be. This is especially true when it comes to integrating DPDK with an existing legacy codebase. This presentation will look at some of the issues and provide an update on current development and prototyping work to simplify DPDK integration with existing code.

    New Command Line Interface for DPDK

    +

    The current command line interface for DPDK called cmdline has a number of limitation and a complex user design. The next command line for DPDK called CLI is more dynamic with a simple directory style design. The directory style design allows for commands to be placed in a hierarchy for easy integration, plus supporting a simple argc/argv function interface. Using these features reduced the LOC in test-pmd cmdline file from 12K to ~4K. The presentation includes an example usage.

    Event Adapters - Connecting Devices to Eventdev

    +

    Recently, the DPDK has enabled applications to use dynamically load balanced pipelines with the introduction of libeventdev. In addition to using eventdev for CPU to CPU pipelines, devices such as ethdev, cryptodev and timers need to be able to inject events into eventdev. Currently, we are in the process of upstreaming extensions to eventdev called eventdev adapters for each of these devices that would allow applications to configure event input from these devices to the event device. We will discuss each of the adapter APIs and show example code that allow event based applications to be written in a platform independent manner.

    GRO/GSO Libraries: Bring Significant Performance Gains to DPDK-based Applications

    +

    A major part of packet processing has to be done on a per-packet basis, such as switching and TCP/IP header processing. The overhead of the per-packet routines, however, exerts a significant impact on the performance of network processing. Generic Receive Offload (GRO) and Generic Segmentation Offload (GSO) are two effective techniques for mitigating the per-packet processing overhead by reducing the number of packets to be processed. Specifically, GRO merges the receiving packets of the same flow in RX, while GSO delays packet segmentation in TX.

    Power Aware Packet Processing

    +

    A drive to deliver OPEX saving and performance where and when it's needed. Enter a new era of power optimized packet processing. This talk reviews new & existing DPDK extensions for policy based power control proposed in August and the associated performance benefits.

    Enhanced Memory Management

    +

    In this presentation we will be reviewing Enhanced Memory Management techniques and multi-process enhancements as a possible way to seamlessly solve burning issues like slow initialization, memory protection, memory hotplug, dynamic scale up/down, physically vs virtually contiguous, inter-vm shared memory etc.

    Making networking apps scream on Windows with DPDK

    +

    Network bandwidth is precious and milliseconds matter for many user-mode applications and virtual appliances running on both Linux and Windows. In order to get the best network throughput to process and forward packets, developers need direct access to the NIC without going through the host networking stack. Until now, only developers on Linux and FreeBSD platforms were able to use DPDK to obtain these performance benefits but, we are happy to announce that we have an implementation of DPDK for the Windows platform!

    Unbinding Linux kernel drivers to allow userland IO through VFIO has a number of disadvantages such as another large touchy code base to deal with the hardware, loss of standard Linux tools (ifconfig, ethtool, tcpdump, SNMPd...) and impossibility to accelerate container networking. Mediated device introduced in Linux kernel 4.10 for GPUs and provisions for additional devices hold the promise of collaboration between kernel drivers and userland application in need of direct datapath steering.

    Mellanox bifurcated driver model

    +

    Mellanox PMD uses verbs instead of taking full control over the device (PCI). That allows the kernel (netdev) and more than a single PMD to run on a single PCI function. +If the DPDK app is not steering by rte_flow, all the traffic the packets be processed by the kernel net device.

    DPDK with KNI – Pushing the Performance of an SDWAN Gateway to Highway Limits!

    +

    An SDWAN gateway is usually built with an x86 commercial off-the-shelf (COTS) hardware that often runs a variant of Linux Operating System and requires high throughput for connecting a corporate’s branch network with its Data Centers. However owing to the inherent limitations of standard 4K sized pages without dedicated resource allocations in a general-purpose Linux kernel, it has been seen that even a high-end SDWAN gateway hardware cannot forward traffic to its full potential.

    DPDK as microservices in ZTE Paas

    +

    To provide high performance for ICT (Information Communications Technology) area, we use DPDK as a micro service in container networking. We used primary/secondary mode, rte_ring, sharing meory and so on, to promote the performance of datapath. We achieved bidirectional zero-copy between containers in contrast to only dequeue zero copy in vhost-user/virtio-user.

    Accelerate Clear Container Network performance

    +

    Clear Container is a great technology to secure a container with a fast and lightweight hypervisor, and there might be very different type of workloads running inside Clear Containers, e.g. some workloads require high packet processing rate (PPS) and some workloads require massive data transfer (BPS), given Clear Container’s much higher density than Virtual Machine, a high performance virtual switch is very critical and demands is highly emerged, but current available virtual switches is still far behind those demands.

    Accelerate storage service via SPDK

    +

    SPDK (storage performance development kit, http://spdk.io) is an open source library used to accelerate the storage service (e.g., file, block) especially for PCIe SSDs (e.g., 3D Xpoint SSDs). The foundation of SPDK is the user space, asynchronous and polled mode drivers (e.g., IOAT and NVMe), and the idea of which is similar to DPDK.

    The high-level P4 programming language promises protocol and hardware-agnostic design of network functions. As the low-level functional implementation, the P4 Behavior Model (BMv2) provides the necessary constructional blocks (parser, deparser, lookup tables, and action primitives, etc.) into which any P4 dataplane programs can be compiled.

    Reflections on Mirroring With DPDK

    +

    Debugging network problems is often hard, and further complicated when a guest O/S is provided with an SR-IOV VF bound to a DPDK driver because tools running on the physical host (e.g. tcpdump) lose visibility to the interface. Hardware mirroring of traffic to another VF provides the ability to regain visibility and to help facilitate the troubleshooting process.

    A network application API on top of device APIs

    +

    NFV promise is to be able to instantiate or even live migrate VMs on different platforms and have applications benefit from whatever acceleration is available. As a result, the application developer shall not make compilation or define application architecture based on what he/she expects from the runtime environment. ODP and DPDK have in common the concept of "device" APIs (Ethernet, crypto, events, IPsec, compression...) with distinct approaches.

    SafetyOrange is a portable (4.3 liter) and silent Xeon computer. Well, it is larger than 'DPDK in a box' but it supports two NICs (as of now sporting 2 XL710 cards), has 32G of memory and 14 cores. We have been using it for testing both native and virtualized DPDK appliances also whole virtual routers and served as a traffic generator for performance tests (DPDK pktgen), too. It is a brilliant development environment, too. And at the end of the day it still fits into a regular backpack.

    VPP Host Stack

    Although packet forwarding with VPP and DPDK can now scale to tens of millions of packets per second per core, lack of alternatives to kernel-based sockets means that containers and host applications cannot take full advantage of this speed. To fill this gap, VPP was recently added functionality specifically designed to allow containerized or host applications to communicate via shared-memory if co-located, or via a high-performance TCP stack inter-host.
