DPDK Summit, San Jose

Roadmap for Future Releases

This presentation will outline the roadmap for future DPDK releases including 16.11 and 17.02.

Virtualization of Network Packet Monitoring Systems Using DPDK

In order to better plan and utilize their networks, Network Administrators need solutions which give them the visibility into the network. Happiest Minds enabled the transformation of a leading Network Packet Monitoring company to co-create the Network Virtual Packet Monitoring system leveraging the key technology innovations like DPDK.

This presentation will describe the development of NFV use cases such as a virtualized provider edge router (vPE) using the DPDK and FD.io projects.

Technical Panel

The panel will be comprised of some of the technical experts from the DPDK community. It will involve an interactive Q&A with the audience.

DPDK in a Box

DPDK in a Box is small, low-cost DPDK platform running on a Minnowboard. It’s not intended for volume production, but may be useful for universities and independent developers who want to work on DPDK but have a limited budget.

DPDK Vhost/Virtio Status

A lot of development effort has been done to DPDK vhost-user/virtio recently, including improving the performance, enhancing the stability and adding more functionality. This presentation will describe some recent enhancements including vhost-user multiple-queue and vhost-user reconnect.

Understanding the Performance of DPDK as a Computer Architect

In our experiments, OVS­DPDK can achieve a maximum of 8x throughput increase compared with vanilla OVS. To understand the performance difference, we leverage advanced profiling tools such as Intel VTune Amplifier and Linux perf [4] to investigate in detail what system architecture parameters are affected by OVS­DPDK for achieving the speedups.

DPDK, VPP/FD.io and Accelerated Open vSwitch

In this talk, Mr. Herbert compares VPP with Open vSwitch. Although both VPP and OVS utilize DPDK for data plane acceleration, they are very different in internal architecture and implementation. Mr. Herbert will discuss these differences in the context of various use cases and how performance can vary and how in different uses one may shine while the other may falter.

PISCES: A Programmable, Protocol-Independent Software Switch

Software switches are typically based on a large body of code, and changing the switch is a formidable undertaking. Instead, it should be possible to specify how packets are processed and forwarded in a high-level domain-specific language (DSL) such as P4, and compiled to run on a software switch. We present PISCES, a software switch derived from Open vSwitch (OVS) DPDK-based implementation, a hard-wired hypervisor switch, whose behavior is customized using P4.

Berkeley Extensible Soft Switch (BESS)

This presentation will describe the Berkeley Extensible Soft Switch (BESS).

Change Before You Have to Be Claimed
[from  Change Before You Have To. (Jack Welch)]

In this talk, we share the latest experiment and performance tuning knowledge of scale-out NFV environment in ShowNet of Interop Tokyo 2016. We deployed a set of DPDK-enabled routing VNFs on DPDK-enabled hypervisor vSwitch called Lagopus vSwitch with DPDK vhost-user PMD to examine their performance scalability.

Transport Layer Development Kit (TLDK)

This presentation describes the Transport Layer Development Kit (TLDK), which is an FD.io project that provides a set of libraries to accelerate L4-L7 protocol processing for DPDK-based applications. The initial implementation supports UDP, with work on TCP in progress. The project scope also includes integration of TLDK libraries into Vector Packet Processing (VPP) graph nodes to provide a host stack.

DPDK in Overlay Networks and How it Affects NFV Performance

One approach to network virtualization is via end-system IP/VPN based overlays. To implement these end-system IP/VPNs, often a kernel based software module is leveraged. However, when the module resides in the host kernel, it incurs a performance penalty. To alleviate these performance penalties, the OpenContrail implementation leveraged DPDK and ported the kernel based distributed forwarding module to the user space.

Innovative NFV Service-Slicing Solution Powered by DPDK

In this presentation, the speaker will talk about:

• Introduction of ‘Service-Slicing-Gateway’ that realizes the IoT-service-slicing
• Why DPDK is necessary
• How we overcome the issues faced in the past NFV development

Why are Open and Programmable Data Planes Critical to the Future of Networking?

This talk will present the need for programmability and openness of the data plane and the benefits to the networking industry as a whole. Specifically the talk will include details on P4, a high-level, networking domain-specific and open programming language and the ecosystem that is burgeoning around it.

Getting Your Code Upstream Into DPDK

In you have a simple one-line patch or a full blown Poll Mode Driver this talk will explain how to get that code upstream into DPDK. It will discuss the DPDK community, the mailing list, the patch process, the contributors guides, the ABI policy, code reviews, documentation and other aspects that make up the DPDK ecosystem.

Putting DPDK in Production

This presentation will cover:

• User perspective on DPDK, including consumability and packaging considerations
• The importance of ABI stability and Long Term Support
• Security for DPDK guest and host (DPDK vswitch)

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.
