Access to the IETF network
The NOC team has an ongoing experiment that allows you to join the IETF network remotely as well as at an IETF meeting venue.
Requests for networking capabilities beyond wireless access to the IETF network (e.g., wired ports, L2 access, prefix delegation) can be sent to support@ietf.org.
All requests are addressed on a best effort basis. Advance notice is appreciated and improves the odds of your request being fulfilled.
Champions can request a Webex account they can use to schedule meetings for their team. These are similar to the Webex accounts allocated to working group chairs to be used for virtual interim meetings. An account can be requested by a team champion at any time. Accounts will remain active and available for the duration of the IETF meeting. Request your account HERE. In the request form, you can use your project name where it asks for "Working Group Name" ("Hackathon Project Name").
In addition to registering for the Hackathon and subscribing to the Hackathon list. It is recommended to monitor both the Hackathon wiki and the list as the Hackathon approaches, determine which project(s) are of interest to you, and reach out to the champions of those projects to determine how best to be involved and coordinate with the rest of the team working on each project.
Champions are welcome and encouraged to list times and mechanisms for collaborating with their team in the Team Schedule. Participants can use this page to determine how and when to reach other team members.
The Hackathon kickoff and the project results presentations can be joined via Meetecho. The Hackathon Zulip stream may be used for general and project specific communication.
All Hackathon participants are free to work on any code. The rules regarding that code are what each open source project and each participant's organization says they are. The code itself is not an IETF Contribution. However, discussions, presentations, demos, etc., during the Hackathon are IETF Contributions (similar to Contributions made in working group meetings). Thus, the usual IETF policies apply to these Contributions, including copyright, license, and IPR disclosure rules.
Note, all projects are open to everyone. However, some champions have identified their projects as being particularly good for those who are new to the IETF or new to the Hackathon. These projects are marked with a star, i.e. *. If you are championing a project that is great for newcomers, please add a * at the end of your project name.

Thread Overview
Thread is a specification for how to carry IPv6 datagrams over a self-configuring mesh of low-power IEEE 802.15.4 wireless links. Stuart Cheshire gave a brief presentation about Thread at the IETF 119 IAB Open meeting in Brisbane. The Thread specification is developed and published by the Thread Group. There are several independent implementations of Thread, the main one being the OpenThread open source project. This Hackathon event is open to all β Thread Group membership is not required, though of course Thread Group members are also welcome to participate.

Objectives
Space communications have large delays (2 secs one-way delay to Moon, 4-22 mins to Mars) and intermittence (because relay orbiters going on the other side of the celestial body). The key adaptations to make to the IP stacks are (briefly, see drafts for details) - for forwarders facing intermittence, store temporarily packets instead of dropping them, when a link goes down - adjust transport and application timers. The TIPTOP working group is making group progress on specifications. The purpose of this experiment is to start trying early implementations and get experience on using applications in this environment.
We will be broadcasting two SSID on the hackathon wireless network: ietf-moon which will inject a 2 seconds one-way delay and ietf-mars which will inject a 4 minutes delay. Both will also see intermittence. Everybody is very welcome to participate and test the network, but make sure to follow the instructions as typical Internet applications won't work as is in this environment.

Artificial Intelligence (AI) is rapidly reshaping industries and daily life, driven by advances in large language models (LLMs) such as ChatGPT, Claude, Grok, and DeepSeek. These models have demonstrated the transformative potential of AI across diverse applications, from productivity tools to complex decision-making systems. However, the effectiveness and reliability of AI hinge on two foundational processes: training and inference. Each presents unique challenges related to data management, computation, connectivity, privacy, trust, security, and governance. In this project, we introduce the Data and Agent Aware-Inference and Training Network (DA-ITN) framework β a unified, intelligent, multi-plane network architecture designed to address the full spectrum of AI system requirements. The architecture features dedicated control, data, and operations & management (OAM) planes to orchestrate training, inference, and agentic services while ensuring reliability, transparency, and accountability.
In this demo, we will be showcasing the first look into a concept that we refer to as data descriptors. These are unique extractions collected from data available for training and can be used to guide the all of the AI services that the DA-ITN enables. As an exampled, we will be demonstrating how these data descriptors are used to facilitate efficient sequential training of a model across a knowledge sharing network that consists of a number of connected data nodes and an orchestrator.

The Static Context Header Compression (SCHC) mechanism is a framework that reduces protocol overhead in IoT environments, where computing resources are limited (little memory or processing power, large battery life-span constraints, ...).
As its name suggests, SCHC relies on a static shared context, or set of rules, to be able to compress and decompress network packets. This is a challenge in highly dynamic or constantly evolving network traffic.
The CORECONF (CoAP Management Interface) standard is a promising means to manage client/server resources and configurations in constrined networks.
We propose extending the SCHC framework with rule and context management capabilities through CORECONF, to make it possible to adapt SCHC rules on the fly.

Test interoperability of Post Quantum algorithms in x.509 structures (Certificates, keys, CMS and other drafts). This project started in November 2022 and continues to evolve. We currently have some github automated actions to automaticlaly test submitted artifacts allowing implementations to get immedidate feedback on their compatibility. This allows us to test interoperability between different algorithm implementations, gain experience using these new algorithms, and provide feedback to the standards groups about practical usage.
A good starting place is our Github repository: https://github.com/IETF-Hackathon/pqc-certificates
For information on OIDs used to create interoperable structures, consult: https://github.com/IETF-Hackathon/pqc-certificates/blob/master/docs/oid_mapping.md
At IETF 124, we plan to add more automation and others are invited to test interoperability. Also, the composite signatures recently had IANA OIDs assigned, so a number of people are interested in testing composite signatures interoperability.

Deployment of Remote Attestation (RA) in the field is complicated by a lack of standard mechanisms to help combine it with existing protocols. Most notable is the lack of any widely-deployed approach to leveraging PKI and RA together to set up a secure channel. The newly minted Secure Evidence and Attestation Transport (SEAT) WG aims to standardize solutions in this space. The Remote Attestation with Exported Authenticators (draft-fossati-seat-expat) draft is meant to provide a solution for integrating RA into a TLS stack. This hackathon project deals with producing working code for draft-fossati-seat-expat.

RADIUS has had 30 years of protocol issues. The existing specifications say that servers must discard well-formed, authentic, packets from known clients. There are no provisions for rate limiting packets. In many cases, packets are sent and never see a reply, which contributes to network instability.
We want to add some functionality (current plan is to focus primarily on Protocol-Error) to RADIUS servers (FreeRADIUS, radsecproxy, Radiator)

Multipath Traffic Engineering (MPTE) is a traffic engineering (TE) paradigm that combines TE with Equal/Unequal-Cost Multipath (ECMP/UCMP) load-balancing. The notions of MPTE and of an MPTE Directed Acyclic Graph (MPTED) tunnel are introduced in [draft-kompella-teas-mpte]. An MPTED tunnel is a Traffic Engineering (TE) construct that contains a constrained set of paths representing an optimized Directed Acyclic Graph (DAG) from one or more ingresses to one or more egresses. The paths that make up an MPTED tunnel traverse a set of junction nodes, and the state associated with the MPTED at each junction node constitutes a set of previous-hops and a set of next-hops over which traffic is load-balanced in a weighted fashion. Provisioning an MPTED tunnel in a TE network using a signaling protocol involves provisioning control and forwarding plane state at each junction node. An MPTED tunnel may be realized over a Multiprotocol Label Switching (MPLS) forwarding plane or a native Internet Protocol (IP) v4/v6 forwarding plane using an appropriate tunnel type. Depending on the deployment needs, a centralized or a distributed approach MAY be adopted for provisioning an MPTED tunnel.

PacketScope is a general-purpose protocol stack analysis and debugging tool based on eBPF. It integrates performance optimization, anomaly diagnosis, and security defense to provide fine-grained tracing and intelligent analysis of network packets at the protocol stack level. The project aims to solve common pain points such as difficult diagnosis of performance bottlenecks, unclear packet transmission paths, and hard-to-detect low-level protocol attacks (e.g., at layers below traditional WAF/IDS).
The tool consists of three main microservice modules:
