We are pleased to announce the Call for Participation for the FOSDEM 2026 Network Devroom The FOSDEM Network devroom hosts a diversity of talks covering open source networking projects and technologies. The scope of the Network devroom is broad and targets those software developers engaged in network design, monitoring, management and software development with open source tools. We typically host a variety of talks on networking topics including: - Network monitoring (inventory, discovery and telemetry) - Network management (enterprise, carrier-grade, cloud, IoT) - Networking protocols (the full alphabet soup) - Cybersecurity (IPS, IDS, Deep-Packet Inspection) - Development tools (libraries, SDKs, plugins) - Network stacks Suggested Topics ================ If it moves network packets, monitors, or interacts with, or supervises entities that move network packets, it is likely a topic the devroom is interested in. A very /non-exhaustive/ list of the projects and topics we would love to see on the schedule are: Monitoring and Observability: Prometheus, OpenTelemetry, ntopng, AI-driven analysis Programmable Data Planes: XDP/eBPF, DPDK, FD.io/VPP, PF_RING, Snabb, P4, Grout Cloud-Native Networking: Cilium, Calico, Istio, Linkerd Routing and Switching: FRRouting, BIRD, OVN, Open vSwitch, EVPN, SRv6 Security and Visibility: Zeek, Suricata, nDPI, Wazuh, CrowdSec, TLS/QUIC visibility Scanning and Testing: nmap, zmap, TRex, Scapy, OpenVAS Telcos: Magma, free5GC, Nephio, O-RAN, MEC and edge networking Tunneling and Security: IPsec, strongSwan, Openswan P2P: libp2p, Matrix, IPFS, DHTs Tooling: benchmarking, network emulation, CI/CD for networking Hardware offloads: Smart NICs, Network processors, SoCs Talks should be aimed at a technical audience, but should not assume that attendees are already familiar with your project or how it solves a given problem. Talk proposals may cover very specific solutions to a problem, or may be a higher-level project overview for lesser-known projects. Important Dates =============== Submission open: 30th October 2025 Submission deadline: 5th December 2025 Acceptance notifications: 12th December 2025 Final schedule announcement: 15th of December 2025 Devroom: 31st of January Proposals ========= We invite short (20–25 min) talks, demos, and lightning talks (5–10 min) showcasing open-source tools, frameworks, standards, or community experiences.

by Quentin Monnet 30 Oct '25

30 Oct '25

We are delighted to announce the Call for Participation for the second eBPF Devroom at FOSDEM! Mark the Dates -------------- * December 1st, 2025: Submission deadline * December 15th, 2025: Announcement of accepted talks and schedule * January 31st, 2026: eBPF Devroom at FOSDEM eBPF at FOSDEM -------------- Originally introduced to make the Linux kernel more programmable, eBPF allows users to load safe and efficient programs into the kernel, in order to implement custom logic running on specific events. The main use cases include kernel or user-space tracing and monitoring, network packet processing, security policies enforcement, and process scheduling. Today, eBPF also extends to Windows, user-space runtimes, and hardware offloads. The depth of the ecosystem has expanded far beyond its original goals and has seen increasing adoption from both enthusiasts and professionals within the open-source community, while the list of use cases and eBPF-based projects continues to grow. After hosting a number of eBPF-related talks in various devrooms over the years, FOSDEM 2026 welcomes a devroom dedicated to eBPF for the second time! This devroom aims at gathering talks about various aspects of eBPF, ideally on multiple platforms. Topics of Interest ------------------ FOSDEM is an event centered on free and open-source software development, and brings the opportunity to reach a large audience of knowledgeable, highly technical open-source software activists. If you have something to present about eBPF, we would love for you to consider submitting a proposal to the Devroom. The projects or technologies discussed in the talks MUST be open-source. Topics of interest for the Devroom include (but are not limited to): * eBPF development: recent or proposed features (on Linux, on other platforms, or even cross-platform), such as: * eBPF program signing and supply chain security * Profiling eBPF with eBPF * eBPF-based process schedulers * eBPF in storage devices * eBPF verifier improvements or alternative implementations * eBPF for profiling AI workloads * Deep-dives on existing eBPF features * Working with eBPF: best practices, common mistakes, debugging, etc. * eBPF toolchain, for compiling, managing, debugging, packaging, and deploying eBPF programs and related objects * eBPF libraries, in C/C++, Go, Rust, or other languages * eBPF in the real world, production use cases and their impact * eBPF community efforts (documentation, standardization, cross-platform initiatives) The list is not exhaustive, don’t hesitate to submit your proposal! Format ------ FOSDEM 2026 will be an in-person event in Brussels, Belgium. We do not accept remote presentations. We’re looking for 20- to 30-minute presentations. The duration should include time for questions: allow at least 5 to 10 minutes to answer questions from the public. Note that due to time constraints, we may end up offering a slot duration different than the one requested when submitting. If you have specific duration requirements, we encourage you to mention them in your proposal. You can look at last year's schedule for inspiration, at https://archive.fosdem.org/2025/schedule/track/ebpf/ How to Submit ------------- Please submit your proposals on Pretalx, FOSDEM’s submissions tool, at https://pretalx.fosdem.org/fosdem-2026/cfp Make sure to select “eBPF” as the track. Code of Conduct --------------- All participants at FOSDEM are expected to abide by the FOSDEM’s Code of Conduct. If your proposal is accepted, you will be required to confirm that you accept this Code of Conduct. You can find this code at https://fosdem.org/2026/practical/conduct/ Devroom Organisers ------------------ * Alexei Starovoitov * Andrii Nakryiko * Bill Mulligan * Daniel Borkmann * Dimitar Kanaliev * Quentin Monnet * Yusheng Zheng If you have questions about any aspects of this Call for Participation, please email us at ebpf-devroom-manager(a)fosdem.org, and we will do our best to assist you.

If you are unsure about what direction to take a topic, please reach out so we can assist you. Talks should be aimed at a technical audience, but should not assume that attendees are already familiar with your project or how it solves a given problem. Talk proposals may cover very specific solutions to a problem, or may be a higher level project overview, particularly for lesser known projects. Recordings of the prior Energy devroom sessions can be viewed at https://archive.fosdem.org/2023/schedule/track/energy/ https://archive.fosdem.org/2024/schedule/track/energy/ and https://archive.fosdem.org/2025/schedule/track/energy/ which may be useful examples for preparing your proposal. Please feel free to suggest a duration between 15 minutes and 45 minutes (making sure to account for time for questions) but note that the final decision on talk durations will be made by the devroom managers based on the number of received proposals. We may decide to schedule shorter slots so that more speakers can participate. ## Key dates * 1st December: CfP submission deadline * 15th December: Announcement of selected talks * 31st January: Energy devroom at FOSDEM, you must be available onsite (in Brussels, Belgium) to present your talk.
