Abstracts

Heads-up Talk: Towards a Common Measurement Framework for Large-Scale libp2p Deployments using CBOR-based Verifiable Telemetry

• Authors: Johanna Moran, Manu Sheel Gupta Abstract:
  Large-scale peer-to-peer systems have evolved from experimental research prototypes into critical Internet infrastructure supporting decentralized storage, content distribution, blockchain consensus, and increasingly autonomous agent-based applications. Networks such as Ethereum, IPFS, Filecoin, Celestia, and other decentralized ecosystems collectively operate hundreds of thousands of nodes across heterogeneous network environments, making them valuable real-world laboratories for protocol measurement and analysis.

Heads-up talk: Measuring OAuth in MCP: Migration from DCR to CIMD

• Authors: Paul Craleton Abstract:
  The Model Context Protocol (MCP) connects AI applications to third-party servers using OAuth 2.1, and its authorization model has driven real-world deployments of open dynamic client onboarding. This talk presents measurement data from this transition across the MCP ecosystem. We show the relative adoption of CIMD versus DCR over time, and compare token refresh success rates between clients using each mechanism, quantifying the user-visible reliability cost of client record purging under DCR.

Feeding the Crawlers: An Experiment in Deliberate Bot Attraction

• Authors: Dan Silvers Abstract:
  As AI training pipelines grow hungrier for fresh data, the crawlers feeding them have grown increasingly aggressive — creating a meaningful measurement problem. We present ACPWB.com , a fictitious company website designed to attract, classify, and measure AI crawler activity through an abundance of synthetic content. This short talk presents the methodology and preliminary findings from this grand experiment, along with some ideas for future exploration.

A Browser's Perspective: Surprises and Insights from Firefox Networking Telemetry

• Authors: Oskar Mansfeld Abstract:
  Firefox collects anonymized networking telemetry from 200 million monthly active users. A large share of these measurements is directly relevant to maprg and the IETF: congestion control behavior, dns timings, path and connection characteristics, QUIC adoption, protocol evolution and distribution, happy-eyeballs-v3 performance, and more.

Traceroutes

• Authors: Sebastian Kappes (Max Planck Institute for Informatics), Tobias Fiebig (TU Wien), Anja Feldmann (Max Planck Institute for Informatics), Johannes Zirngibl (Max Planck Institute for Informatics) Abstract:
  Traceroute is an important Internet measurement tool used to infer the Internet’s topology and to identify middleboxes. However, we show that TTL jumps exist on the Internet: some devices rewrite the TTL, often to larger value of up to 255. Based on controlled experiments and public data from RIPE Atlas and CAIDA Ark, we show that at least 47 ASes are impacted by path-impairing devices that rewrite the TTL.

Measuring Deployment Characteristics of Post-Quantum TLS Authentication Mechanisms

• Authors: Nalini Elkins Abstract:
  The transition to post-quantum cryptography introduces multiple deployment choices for TLS authentication, including traditional X.509 certificates using ML-DSA, Merkle Tree Certificates (MTC), and other emerging mechanisms. While the cryptographic properties of these approaches are relatively well understood, there is comparatively little operational evidence to help architects evaluate their practical deployment implications. This presentation describes an active measurement methodology for evaluating post-quantum TLS deployments.

Understanding DNS Dynamics over the Starlink Network

• Authors: Robert Richter, Vaibhav Bajpai (Hasso Plattner Institute, University of Potsdam) Abstract:
  Low-Earth Orbit (LEO) satellite networks have as a viable Internet connectivity option, yet their Domain Name System (DNS) behavior remains largely unexplored. This paper presents the first dedicated measurement study of DNS performance in the Starlink network. Our measurements reveal that DNS latency in Starlink is predominantly determined by the satellite hop rather than terrestrial routing, with the CGNAT hop (100.64.0.1) accounting for approximately 69 % of total latency in traceroute measurements.

The Future of DNS Privacy: A Comparison of DNS over QUIC and DNS over HTTP/3.

• Authors: Newton Masinde Abstract:
  Abstract: This study presents a large-scale empirical analysis of DNS-over-Encryption (DoE) protocols, focusing on the adoption, protocol feature support, and impact on webpage loading performance. We conducted measurements across over three thousand DoE resolvers, characterizing their support for features such as session resumption and 0-Round-trip Time (RTT) in DNS-over-QUIC (DoQ) and DNS-over-HTTP/3 (DoH/3). Our extensive latency measurements demonstrate that both protocols perform comparably, with DoQ slightly outperforming on average.

Detecting and Characterizing Exposed BGP Routers

• Authors: Shyam Krishna Khadka (University of Twente), Suzan Bayhan (University of Twente), Ralph Holz (University of Twente, University of Münster), Cristian Hesselman (University of Twente, SURF) Abstract:
  RFC 7454 on BGP operations and security recommends that network operators restrict access to TCP port 179, which routers use to receive reachability messages from their peers. This paper presents a detailed insight into this underexplored problem of exposed BGP routers using an Internet-wide TCP scan of port 179. We identify 141,313 IP addresses that accept TCP connections and exchange OPEN messages, corresponding to 20,432 routers across 4,194 Autonomous Systems (ASes).

Noisy Routers: Investigating the Make-Up of Route Collector Data

• Authors: Ebrima Jaw (University of Twente) Abstract:
  The Border Gateway Protocol (BGP) is a crucial inter-domain routing protocol that uses update messages to enable Autonomous Systems (ASes) to share network reachability information. We identify and characterize high-frequency repeated updates driven by a small fraction of sessions and prefixes.

2. draft-cacciapuoti-qirg-quantum-native-architecture

Abstract : draft-cacciapuoti-qirg-quantum-native-architecture

3. draft-irtf-qirg-qi-multiplane-arch

Abstract : An update on the draft proposing a framework for integrating Quantum Internet services with the current Internet, which the authors believe is close to get ready for last call. The new version includes the introduction of the QUI concept, bridging the gap between the quantum fabric and the service strata, and analysis of how a number of relevant papers in the literature would map to the proposed framework.

4. Building a hybrid infrastructure, combining real and emulated resources

Abstract : We introduce the results regarding hybrid systems, and how they can be used to experiment with service concepts at scale. The current results are basically related to QKD, given the availability of such devices, but there are plans to extend these experiments beyond, as entanglement fabric devices become available.

5. Beyond-QKD Applications of Quantum Networks

Abstract : While quantum memories remain a significant technological frontier, estimated to be a decade away from practical commercialization and deployment, many countries — including most EU member states — are actively deploying long-distance quantum key distribution (QKD) networks using commercially available hardware. This raises an important question: what other applications can leverage the prepare-and-measure or entanglement-generating quantum network hardware built for QKD?

In this talk we will present a literature review including a comprehensive compilation of quantum network applications beyond-QKD that do not rely on quantum memories; each with accessible descriptions, clear hardware requirements, and explicit statements on achievable quantum advantage. We aim to start a conversation between researchers and operators about emerging use cases and deployment pathways for existing quantum technologies.

Abstracts and bios

Mark Nottingham — Cloudflare

AI in Standards Participation

Abstract

AI is increasingly used to research, write, and implement Internet standards — and, increasingly, to participate in standards discourse itself. As an assistive technology, it can lower barriers for those facing language or other obstacles. However, it also makes it easy to participate with limited human effort or understanding, straining a community whose value rests on a finite pool of expert attention.
This talk demonstrates ietf-llm , a tool for querying a working group’s or research group’s public record, and uses it to ground a discussion of where AI helps participation, where it harms it, and what norms the IETF and IRTF might adopt in response.

Speaker bio

Mark Nottingham works on Internet and Web standards at Cloudflare. He is a long-time contributor to the IETF and a member of the Internet Architecture Board (IAB).

Marcelo Santos — Federal Institute of Sertão Pernambucano

From Draft to RFC: Mapping the Mortality of Internet-Drafts across the IETF and IRTF

Abstract

It is well known that most Internet-Drafts never become RFCs. This talk shares early, work-in-progress findings from a study that looks at where in the process drafts tend to stall, using the IETF Datatracker to reconstruct each draft’s lifecycle, including its outcome, authors, affiliations, geography, and process history.
So far, the results suggest that a draft’s fate is shaped largely at one key point: Working Group adoption. Some patterns that appear clear in simple comparisons, such as differences by region, by area, or between the IETF and IRTF, seem to change once adoption is taken into account.
These are preliminary observations rather than firm conclusions, and the analysis is still being refined. The aim of the talk is to share the approach and initial signals, gather feedback, and discuss what they might mean for lowering barriers to entry.
