DPDK and 802.11 - Robert McMahon, Umber Networks

Tuesday May 12, 2026 09:25 - 10:10 CEST

Rum 17+18 - Floor 3

DPDK transformed wired networking by giving host software direct control over packet processing. This talk makes the case that the same approach should be applied to 802.11 wireless.

Wi-Fi’s real behavior—contention, TXOP scheduling, A-MPDU aggregation, rate adaptation, and retries—is hidden below the 802.3 interface inside firmware and hardware state machines. This prevents per-packet observability and programmable control.

We propose a Wi-Fi Poll Mode Driver model that operates natively on 802.11 frames, exposing aggregation and retry behavior as first-class metadata and accepting explicit transmission parameters (MCS/NSS/BW, TXOP limits, retry policy). With this interface, a DPDK application can coordinate microsecond-scale MAC scheduling with millisecond-scale ECN/AQM control.

We outline the required PMD interface, metadata surface, and driver hooks needed to bring software-defined control to wireless networking.

Applying Header–Data Split To Zero-Copy Data Transfer - Dapeng Sang & Wei Yan, ByteDance

Tuesday May 12, 2026 10:15 - 10:25 CEST

Rum 17+18 - Floor 3

In this presentation, we will explore the application of header-data split in zero-copy mechanisms within a disaggregated userspace protocol stack to improve performance and multi-tenant memory safety. We focus on two key points:
1. Performance Optimization
a. Zero-Copy: Achieve zero-copy between the application and the NIC, reducing latency and saving CPU resources.
b. Cache Efficiency: By applying HDS, the userspace stack only loads the protocol headers, reducing cache pollution and making protocol parsing faster.
c. Cross-Socket Access: Headers and payloads can reside on different sockets, eliminating the need for remote data access by applications.
2. Memory Permission Isolation
a. Memory Sharing and Safety: Each application creates memory pool and shares it with the userspace stack. Only read permission is retained in userspace stack after registration on device.
b. Fault Containment and Protection: In the event of memory exceptions in either the application or the userspace stack, their operational stability remain unaffected.
Through detailed design, we have enhanced the performance and safety. Attendees will get an in-depth look at the practical application.

Bridging DPDK and NIC HQoS With Priority-Aware Backpressure - Rubens Figueiredo, BISDN GmbH

Tuesday May 12, 2026 10:55 - 11:25 CEST

Rum 17+18 - Floor 3

Hierarchical QoS (HQoS) in DPDK enables fine-grained shaping across tens of thousands of flows, but scaling beyond a single core remains challenging. While rte_sched offers flexible software HQoS, synchronization and cache overheads constrain multi-core performance. Modern NICs such as the Intel E810 offer line-rate hardware HQoS, but only at coarse granularity, lacking per-flow control. Partial offload combines both data planes, preserving fine-grained control in software and aggregate shaping in hardware. However, for current partial offloads, the split is uncoordinated. Software selects packets assuming TX capacity is available, but under overload, the NIC may accept only part of the burst, dropping some packets. Because these drops occur after the scheduler, high-priority traffic may discarded, breaking QoS guarantees and increases latency. We introduce Priority-Aware Backpressure (PAB), an extension to DPDK that treats NIC TX failures as congestion signals and dynamically adjusts dequeue budgets per priority. PAB keeps drops within scheduler control, preventing high-priority loss and maintaining stable latency under sustained overload across eight schedulers and 32000 flows.

Finding the Best Path To the Kernel - Stephen Hemminger, Independent

Tuesday May 12, 2026 11:30 - 12:00 CEST

Rum 17+18 - Floor 3

DPDK offers multiple virtual devices for kernel packet exchange: tap, af_packet, af_xdp, pcap, and virtio-user. This talk benchmarks all five approaches and provides guidance on selecting the right one for your use case.

When DPDK applications need kernel connectivity—control plane traffic, management interfaces, or integration with kernel services—developers must choose among several virtual devices. Direct comparisons are scarce.

Grout: Two Years in - Building a Production-Ready DPDK Router - Robin Jarry, Red Hat

Tuesday May 12, 2026 13:35 - 14:05 CEST

Rum 17+18 - Floor 3

grout, an official dpdk.org project, is modular DPDK-based software utilizing the DPDK graph library. This is the third project update, following presentations in September 2024 and May 2025.

The talk will start with a brief recap of grout's design principles: strict separation between control and data planes, OSI layer-based module organization, and runtime configuration via a socket API.

Since May 2025, major updates include an OpenMetrics exporter for production monitoring, a DHCP client for dynamic addresses, improved control plane interfaces for FRR integration, continued multi-VRF work, and Layer 2 bridging with MAC learning. We will discuss the technical challenges and solutions.

We will discuss concrete deployment scenarios: integrating grout with OpenStack Neutron as a third-party L3 provider, and using grout as a PE router in Kubernetes environments. Each use case highlights different grout capabilities.

Finally, you will discover our roadmap for the coming year. Bring your use cases, features and ideas so we can integrate them in the roadmap: what should be added to grout so you can use it?

Integrating FRR With Grout - Robin Jarry, Red Hat

Tuesday May 12, 2026 14:10 - 14:40 CEST

Rum 17+18 - Floor 3

DPDK-based routing stacks often integrate with Linux by using the kernel as the primary routing and control point, with routing state mirrored into a userspace dataplane. While effective, this model couples the dataplane closely to kernel routing semantics.

This talk explores an alternative architectural approach: treating the DPDK dataplane itself as the routing data plane. Grout is designed to integrate directly with FRRouting (FRR), with routes programmed from FRR straight into Grout, without requiring a kernel FIB.

Using FRR’s dataplane (dplane) API, we developed a Zebra dataplane plugin that intercepts routing operations before kernel installation and translates routes, nexthops, addresses, and VRF information into Grout API calls. This avoids kernel-to-userspace route synchronization and simplifies control/data-plane interactions.

TAP and TUN interfaces provide Linux connectivity for FRR protocol daemons (BGP, OSPF, IS-IS), while packet forwarding remains in DPDK. We also discuss VRF integration, including mapping Linux VRF identifiers to Grout VRF IDs, and present a reusable design pattern for integrating FRR with DPDK-based routing data planes.

DPDK Powered Data Acquisition Systems at CERN - Roland Sipos, CERN

Tuesday May 12, 2026 15:25 - 15:55 CEST

Rum 17+18 - Floor 3

At CERN, the European Organization for Nuclear Research, DPDK has evolved from a performance enabler to a common technology for data acquisition and readout systems across multiple practical use-cases. It is deployed in production in multiple experiments like NA62 and in the prototype detectors at CERN’s Neutrino Platform, and forms part of the architectural foundation for large-scale experiments like DUNE.
For NA62, DPDK replaced a commercial, licensed networking solution, enabling a fully open-source readout stack with improved maintainability and long-term sustainability.
In the DUNE experiment’s prototypes, the challenge was not only transitioning from custom protocols to standard Ethernet, but scaling to multi-100Gbps UDP inputs per computing node. This required NUMA-aware architecture, RX queue partitioning, multi-process separation of control and data planes, memory pool tuning, burst optimization, and careful interrupt and polling strategies to sustain deterministic throughput.
The talk presents concrete architectural patterns, tuning strategies, and operational lessons from large-scale, long-running deployments for physics experiments at CERN.

Running a High-Performance DPDK-Based Router on Kubernetes - Andrea Panattoni, Red Hat

Tuesday May 12, 2026 16:00 - 16:30 CEST

Rum 17+18 - Floor 3

Grout is a DPDK-based software router that supports IPv4/IPv6
forwarding, VRFs, NAT, and FRR integration. Deploying it, as any DPDK application, inside a Kubernetes pod presents a fundamental challenge: DPDK expects direct hardware access, hugepages, and dedicated CPU cores, while Kubernetes abstracts all of these away by design.

This talk walks through deploying Grout on Red Hat OpenShift, leveraging the platform's operator ecosystem to bridge the gap between DPDK's hardware requirements and Kubernetes' abstraction model. It covers the full stack: configuring the SR-IOV Network Operator to expose virtual functions, using the Node Tuning Operator and PerformanceProfiles to guarantee isolated CPUs, Hugepages, and NUMA-aligned scheduling, and packaging Grout as a container that can consume these resources.

Using DPDK on Embedded RISC-V Cores of a NIC - Dmitry Kozlyuk, Mitigator Global

Tuesday May 12, 2026 16:35 - 17:05 CEST

Rum 17+18 - Floor 3

Data-path accelerator (DPA) is an NVIDIA BlueField-3 subsystem that consists of a large number of RISC-V cores integrated with the NIC fabric. DPA cannot comprehensively host DPDK, because DPA is running an RTOS without any conventional services except scheduling. Besides, DPDK core abstractions are suboptimal for DPA or have limited use there. On the other hand, it is desired to run advanced and well-tested DPDK algorithms on DPA. Doing so means running DPDK control plane and data plane code on separate HW and in very different environments. We describe the needed adjustments to DPDK libraries to do so and measure the performance of DPDK code running on DPA. We also outline and discuss the gaps that DPDK could overcome to allow its use in such heterogeneous environments.
