SUMMARY:DPDK Userspace\, Dublin
DESCRIPTION:Userspace 2016 was a developer forum which focused on the elements of DPDK which are most pertinent to the open source software community members. The two-day event at the Clayton Hotel in Dublin included highly interactive discussions on the latest features and upcoming changes to DPDK. \n\nDPDK Roadmap\n\nBruce Richardson(Intel) \nThis session will be an open discussion on the DPDK roadmap. It will cover topics such as:\n– What do people plan to contribute to 17.02/17.05?\n– What gaps exist in the roadmap? \n\nVideo | Slides \n\n\nDPDK Hyper-V Support\n\n\nStephen Hemminger(Microsoft) \n\n\nThis presentation will cover the strategy and implications of Hyper-V support in DPDK. \n\nVideo | Slides \n\n\nNFV Use-case Enablement on DPDK and FD.io\n\n\nJasvinder Singh(Intel)\, Cristian Dumitrescu(Intel) \n\n\nThis presentation will discuss the rapid development of NFV use cases such as a virtualized provider edge router (vPE) using the DPDK and VPP framework on Intel multicore CPUs.  Additionally\, this talk will focus on enabling DPDK Hierarchical Quality of Service Schedular (HQoS) in VPP framework. This will include the configuration of HQoS instances and their execution in VPP. \n\nVideo | Slides \n\n\nMbuf Changes\n\nOlivier Matz(6WIND) \n\nThis session will be an open discussion on mbuf changes that are required\, including mbuf extension for external data. \n\nVideo | Slides \n\n\nCryptodev and IPsec Acceleration\n\n\nDeclan Doherty(Intel)\,Damjan Marion(Cisco)\, Sergio Gonzalez Monroy(Intel) \n\n\nThis presentation will consist of 3 parts: \n\nA comprehensive overview of the cryptodev framework in DPDK\, including its architecture\, poll mode drivers\, crypto application development\, and details on the future roadmap.\nAn overview of the Vector Packet Processing (VPP) project in FD.io.\nA description of the integration of cryptodev into VPP to accelerate IPsec.\n\n\nVideo | Slides \n\n\nTransport Layer Development Kit (TLDK)\n\n\nKeith Wiles(Intel) \nThis presentation describes the Transport Layer Development Kit (TLDK) project in FD.io. It will include some performance measurements of TLDK. \n\n\n\nVideo | Slides \n\n\nmOS Networking Stack: A Specialized Network Programming Library for Stateful Middleboxes\n\nProf KyoungSoo Park(KAIST) \n\nStateful middleboxes such as intrusion detection systems and stateful firewalls rely on TCP flow management to keep track of on-going network connections. Implementing complex TCP state management modules for network appliances in high-speed networks is difficult. This is especially more challenging due to the lack of a reusable networking stack that provides a development interface that monitors fine-grained flow states for stateful middleboxes. This presentation describes the middleware Operating System (mOS) which aims to address this gap. \n\nVideo | Slides \n\n\nTRex Traffic Generator – Stateless Support\n\n\n\nHanoch Haim(Cisco) \n\n\n\nThis presentation will give high level of the capability/design of the new stateless features in Trex and how it is used by the FD.io project. \n\nVideo | Slides \n\n\nDPDK Project Growth\n\nTim O’Driscoll(Intel) \n\nAs DPDK continues to expand\, we need to consider what changes need to be made in order to facilitate that growth. One obvious change would be to move the project to an independent body such as the Linux Foundation. \n\nVideo \n\n\nDPDK optimal performance everywhere\n(Rallying with a Formula 1)\n\nThomas Monjalon (6WIND) \n\nThis presentation will be about the fundamentals of DPDK. First of all\, the DPDK userspace drivers process packets at lightning speed. And it runs on several architectures with a long list of supported devices. But the real uniqueness of DPDK is to combine optimal performance with a broad hardware support and à la carte packaging. Surprisingly\, there are always some new promising optimizations to unlock the full power of the hardware. Also\, after 5 years of existence\, the project is still making some progress to be easier to use in more and more environments. Finally it is essential to remember that these improvements are possible thanks to an amazing and fast growing Open Source community. \n\nVideo | Slides \n\n\nIdentifying and Fixing Performance Bottlenecks\n\nBruce Richardson (Intel) \n\nThis presentation will focus on identifying and fixing performance bottlenecks using the Intel® VTune™ Amplifier. An example from the i40e driver will be used to illustrate the process. \n\nVideo | Slides \n\n\nRe-structuring the DPDK Device Driver Framework \n\nShreyansh Jain (NXP) \n\nExpanding DPDK to support non-PCI devices e.g. platform bus devices in a SoC \n\nVideo | Slides \n\n\nMellanox Bifurcated DPDK PMD\n\n\nRony Efraim (Mellanox) \n\n\nMellanox PMD is based on Bifurcated driver and allows the kernel (netdev) and more than one PMD to run on the same PCI. If the DPDK app is not setting a rule to steer this traffic it will be processed by the kernel. \n\nVideo | Slides \n\n\nIntel I40E Bifurcated Driver\n\nJingjing Wu (Intel) \n\nDPDK is known to build the high performing data plane workload on Intel Architecture and platform\, a real world packet processing workload often relies on heavily on the Linux kernel and its large stack for the control plane design and implementation. As a known limit\, Linux performance is not sufficient for high speed data plane workloads. In order to combine the advantages of both\, a few key technical components can be used to make DPDK and kernel stack work and evolve independently. \n\nA high speed data path between Linux kernel and DPDK. (Kernel NIC Interface\, KNI\, TAP).\nA high speed data traffic direction into Linux Kernel and DPDK. (Bifurcated driver\, Virtualization)\n\n\nVideo | Slides \n\n\nInterworking with the Linux Kernel\n\nFerruh Yigit(Intel)  \n\nThis session will be an open discussion on the challenges of interworking with the kernel\, the inability to upstream enhancements like KDP/KCP to either the kernel or DPDK\, and possible next steps. \n\nVideo | Slides \n\n\nMonitoring your DPDK Application/Interfaces with Collectd\nEmma Foley (Intel)\,  Maryam Tahhan (Intel)\, Daniel Parker(Intel) \n\nVideo | Slides \n\ndeb_dpdk – Challenges and Opportunities when Packaging DPDK\n\n\nChristian Ehrhardt (Canonical)\, Luca Boccassi(Brocade) \n\n\nDPDK is special in many ways which make packaging and distributing it a more interesting effort compared to many other programs or libraries. This talk is about challenges we faced\, what we can learn from them and where we expect potential areas of improvement in the future. Working together on those should help DPDK distribution and growing a higher adoption rate. \nVideo | Slides \n\n\nUsability (including packaging\, stable releases\, LTS releases etc.)\n\nJohn McNamara (Intel)\, Christian Ehrhardt (Canonical)\, Luca Boccassi(Brocade) \n\nThis session will be an open discussion on usability\, including topics such as packaging\, stable releases\, LTS releases etc. \n\nVideo | Slide \n\n\nTesting and Continuous Integration\n\n\nQian Xu (Intel) \n\n\nPresentation from Qian on DPDK CI Enhancements. \nThis presentation will focus on testing\, performance testing and CI\, and how these can be further improved. \n\nVideo | Slides \n\n\nOpen vSwitch DPDK Acceleration Using HW Classification\n\nRony Efraim (Mellanox) \n\nHow to use HW classification to accelerate OpenvSwitch DPDK. NIC HW can classify the packets and return flow id that can be used instead of classification the packet by software. NIC HW can classify the packets drop and count them in order to preform aging and statistics. \n\nVideo | Slides \n\n\nAn Implementation of a P4 Software Dataplane Using Open vSwitch\n\n\nCian Ferriter (Intel) \n\n\nP4 is an emerging standard for programming dataplanes. Although its initial applicability is for hardware dataplanes (in particular switching ASICS)\, its paradigm shifting approach to programming the dataplane can equally be applied to software dataplanes with interesting consequences. The first mainstream implementation of a software P4 dataplane is likely to be via Open vSwitch and is based on DPDK. This presentation will talk about this work and what it means to the DPDK community. \n\nVideo | Slides \n\n\nBridging the gap between hardware functionality in DPDK applications and vendor neutrality in the open source community\n\nIan Stokes (Intel)\, Sugesh Chandran (Intel) \n\nTo date there has been multiple efforts to make use of hardware features and functionality in the fast-path of OVS to improve performance e.g. Intel XL710 VxLAN tunnel optimization using flow director feature\, Intel XL710/82599  packet type identification etc. However implementations to date have been hardware specific and as such are not acceptable to the Open vSwitch community due vendor neutrality. Feedback from the Open vSwitch community indicated that what is required is a common hardware API that is vendor neutral and easily consumable. \n\nVideo | Slides \n\n\nTesting and Benchmarking Applications with MoonGen\n\nPaul Emmerich (Technical University of Munich) \n\nMoonGen is a fully scriptable high-speed packet generator built on DPDK and LuaJIT. It can saturate a 10 Gbit/s connection with 64 byte packets on a single CPU core while executing user-provided Lua scripts for each packet. Multi-core support allows for even higher rates\, we have evaluated it at rates above 100 Gbit/s at 200 Mpps. \n\nVideo | Slides \n\nClosing Remarks\n\nJim St. Leger (Intel) \n\nVideo

APIs such as the eth dev API help achieve this to a degree but specific device capabilities and driver behavior beneath the eth dev API make a truly generic approach in OVS DPDK difficult.

This talk introduces a JSON based API to retrieve metrics and telemetry from DPDK. It shows how simple the monitoring of any DPDK application can be if we expose DPDK metrics through a simple RESTful API\, which can be consumed by any service-assurance agent (eg: CollectD). Building this functionality into the DPDK primary application enables the Service Assurance agent to monitor all DPDK applications as generic entities\, instead of each application providing an ad-hoc implementation. \n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-youtube”] Watch Video »\n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-file-pdf-o”] Download Slides »[/vc_column_text][vc_column_text][/vc_column_text][/toggle][toggle color=”Default” title=”Closing Remarks + Identify Topics for BoF Evening Discussions”][vc_column_text]Closing Remarks + DPDK Developer Appreciation awards\, Evening Discussions \nClosing remarks at the end of day one. \n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-youtube”] Watch Video »\n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-file-pdf-o”] Download Slides »[/vc_column_text][vc_column_text][/vc_column_text][/toggle][toggle color=”Default” title=”Scaling the DPDK Community”][vc_column_text]Scaling the DPDK Community\nJohn McNamara\, Intel and Kevin Traynor\, Red Hat\nAs the community continues to grow\, our ability to scale and support our customers is increasingly important.

In open lab\, standard testbeds are designed by each vendor\, and all testbeds are managed centralized. Based on standard testbeds\, a unified test suite can be well defined to cover OSes\, platforms\, NICs and their combination. With standard testbeds and a unified test suite\, execution time is fined controlled and consistent quality indicator can be provided to all users. Meanwhile\, CI system is designed to monitor patches in community\, to trigger build test on each OS\, and to dispatch tests to testbeds in open lab. Finally\, the validation results are showed in CI dashboard. Furthermore\, CI system includes a database in the back-end to support to track quality and performance data. \n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-youtube”] Watch Video »\n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-file-pdf-o”] Download Slides »[/vc_column_text][vc_column_text][/vc_column_text][/toggle][toggle color=”Default” title=”Extending DPDK Flow Classification Libraries for Determinism and Cloud Users”][vc_column_text]Extending DPDK Flow Classification Libraries for Determinism and Cloud Users\nSameh Gobriel\, Intel\nIn this talk we will briefly present new technologies to extend DPDK flow classification libraries to cover more general use cases. We will fist provide an overview of the different classification libraries (e.g. hash library\, EFD library\, membership library\, ..etc.) and highlight the set of usages where each library is a best fit for. Next\, we provide details of new extensions that we are adding to the hash library to support read/write concurrency and guaranteed flow insertion\, Both features\, in our point of view\, are must have for a wide set of usages especially to support telco workloads. Additionally we present new research directions we are investigating on how to use DPDK flow classification libraries to optimize cloud key-value stores. We highlight bottlenecks of the current indexing schemes of such huge stores\, and how DPDK can be augmented (e.g. by extending membership library to support range filters\, and lossy caches\, ..etc.) to help address these bottlenecks. We are soliciting feedback of DPDK developers and users on our new research directions and looking forward to any collaboration opportunity to optimize cloud workloads. \n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-youtube”] Watch Video »\n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-file-pdf-o”] Download Slides »[/vc_column_text][vc_column_text][/vc_column_text][/toggle][toggle color=”Default” title=”Lock-Free Read-Write Concurrency in rte_hash”][vc_column_text]Lock-Free Read-Write Concurrency in rte_hash\nHonnappa Nagarahalli\, Arm\nRecent patches have tried to address the reader-writer concurrency in rte_hash library. However\, these fall short on solving the problem on multiple use cases. These solutions result in further significant problems when the use cases involve preemptible writer threads. Lock-free addition and deletion algorithms are required to truly solve the read-write concurrency. This talk explores the need for lock-free algorithms in the context of rte_hash library\, the changes required in rte_hash for 64bit systems. It will also discuss various options available for solving the issue on 32bit systems and seek feedback. Performance numbers with this proposal will also be presented. \n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-youtube”] Watch Video »\n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-file-pdf-o”] Download Slides »[/vc_column_text][vc_column_text][/vc_column_text][/toggle][toggle color=”Default” title=”Recent Power Management Enhancements in DPDK”][vc_column_text]Recent Power Management Enhancements in DPDK\nDavid Hunt\, Intel\nDPDK PMDs typically poll on rings\, making the cores look 100% busy to the OS. Using Power Management Unit (PMU) counters\, it is possible to differentiate between busy and non-busy poll loops\, allowing scaling down of the core frequency during low-traffic situations\, and scaling up (including Turbo) in high traffic situations\, without modifying the application. A patch demonstrating this method has been added to DPDK 18.08 using the branch hits and branch misses PMU counters. The talk will give an overview of power management techniques in DPDK\, and detail the methods used in the latest DPDK Power Management features. \n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-youtube”] Watch Video »\n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-file-pdf-o”] Download Slides »[/vc_column_text][vc_column_text][/vc_column_text][/toggle][toggle color=”Default” title=”Soft NIC: Build Your Own NIC Pipeline in SW”][vc_column_text]Soft NIC: Build Your Own NIC Pipeline in SW\nCristian Dumitrescu\, Intel\nThis presentation describes the benefits of using the DPDK Soft NIC\, which allows building custom NIC pipelines at the speed of SW development. \n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-youtube”] Watch Video »\n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-file-pdf-o”] Download Slides »[/vc_column_text][vc_column_text][/vc_column_text][/toggle][toggle color=”Default” title=”urdma: A Remote Direct Memory Access verbs provider using DPDK”][vc_column_text]urdma: A Remote Direct Memory Access verbs provider using DPDK\nPatrick MacArthur\, UNH InterOperability Laboratory\nRemote Direct Memory Access (RDMA) provides a low latency\, high throughput network interconnect with kernel bypass and zero copy between application virtual memory regions. RDMA deployments require expensive\, specialized hardware. Software RDMA providers have been developed to allow testing and research of RDMA features without this specialized hardware. Historically\, these software providers\, including softiwarp and softroce (rxe)\, have been implemented in the kernel. Using DPDK\, we have developed an RDMA provider named urdma that performs data transfer entirely in userspace with only minimal connection management in the kernel. The urdma provider uses a variant of the standard iWARP protocol over UDP\, and is capable of running on commodity NICs. The kernel and userspace components of urdma are available under an open-source license. This presentation will discuss goals\, the design and implementation of the provider\, issues encountered during development\, and a performance evaluation. \n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-youtube”] Watch Video »\n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-file-pdf-o”] Download Slides »[/vc_column_text][vc_column_text][/vc_column_text][/toggle][toggle color=”Default” title=”Tungsten Fabric DPDK Based vRouter HW Offloads”][vc_column_text]Tungsten Fabric DPDK Based vRouter HW Offloads\nOlga Shern\, Mellanox\nThere is a wide range of smart/intelligent NICs emerging on the market\, implemented using various technologies. These NICs are capable of being programed to perform advanced packet classification and modification operations\, allowing to implement flexible packet processing pipelines implementing switching\, routing\, tunneling\, etc. This talk will present work being done to accelerate the Tungsten Fabric DPDK based vRouter\, using DPDK rte_flow API to implement a generic\, vendor-agnostic\, open source offload module. We will also discuss potential future enhancements to DPDK rte_flow APIs to enable additional accelerations. \n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-youtube”] Watch Video »\n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-file-pdf-o”] Download Slides »[/vc_column_text][vc_column_text][/vc_column_text][/toggle][toggle color=”Default” title=”DPDK PMD for AF_XDP”][vc_column_text]DPDK PMD for AF_XDP\nXiaoyun Li\, Intel\nAF_XDP\, which can be regarded as an upgraded version of AF_PACKET\, can provide more than 10 times performance improvement. It can also connect the XDP pass-through to user-space directly\, which means an ebpf program that processes packets can be forwarded to an application in a very efficient way. Thus enabling a delicate PMD for AF_XDP is valuable for DPDK applications to benefit from it. In this presentation\, we will share our recent work about enabling a DPDK Polling Mode driver for AF_XDP. Firstly\, we will briefly introduce AF_XDP and why we need a DPDK PMD driver for AF_XDP. Then we will present the implementation details on how to translate AF_XDP language (XDP socket\, ebpf redirect map…) into DPDK language (ethdev\, queue)\, how to reach zero copy between rte_mempool and XDP umem\, and so on. At last\, we will share some ideas for future improvement such as utilizing the busy poll feature to improve performance. \n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-youtube”] Watch Video »\n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-file-pdf-o”] Download Slides »[/vc_column_text][vc_column_text][/vc_column_text][/toggle][toggle color=”Default” title=”DPDK + eBPF”][vc_column_text]DPDK + eBPF\nKonstantin Ananyev\, Intel\nBPF is used quite intensively inside Linux (and BSD) kernels for various different purposes and proved to be extremely useful. BPF inside DPDK might also be used in a lot of places for a lot of similar things. As an example to: – packet filtering/tracing (aka tcpdump) – packet classification – statistics collection – HW/PMD live-system debugging/prototyping – trace HW descriptors\, internal PMD SW state\, etc. The presentation provides information about current status of DPDK eBPF library and ideas for further enhancements and usage scenarios. \n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-youtube”] Watch Video »\n[icon color=”Accent-Color” size=”tiny” icon_size=”” image=”fa-file-pdf-o”] Download Slides »[/vc_column_text][/toggle][/toggles][/vc_column][/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” scene_position=”center” text_color=”dark” text_align=”left” overlay_strength=”0.3″ shape_divider_position=”bottom”][vc_column column_padding=”no-extra-padding” column_padding_position=”all” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_shadow=”none” column_border_radius=”none” width=”1/1″ tablet_text_alignment=”default” phone_text_alignment=”default” column_border_width=”none” column_border_style=”solid”][vc_column_text]\nSponsors:\n \n[/vc_column_text][/vc_column][/vc_row]
