Worryingly, the QAnon conspiracy theory has<br>implications in the real world, with supporters of the theory participating in<br>real-world violent acts like the US capitol attack in 2021. At the same time,<br>the QAnon theory started evolving into a global phenomenon by attracting<br>followers across the globe and, in particular, in Europe. Therefore, it is<br>imperative to understand how the QAnon theory became a worldwide phenomenon and<br>how this dissemination has been happening in the online space. This paper<br>performs a large-scale data analysis of QAnon through Telegram by collecting<br>4.5M messages posted in 161 QAnon groups/channels. Using Google's Perspective<br>API, we analyze the toxicity of QAnon content across languages and over time.<br>Also, using a BERT-based topic modeling approach, we analyze the QAnon<br>discourse across multiple languages. Among other things, we find that the<br>German language is prevalent in QAnon groups/channels on Telegram, even<br>overshadowing English after 2020. Also, we find that content posted in German<br>and Portuguese tends to be more toxic compared to English. Our topic modeling<br>indicates that QAnon supporters discuss various topics of interest within<br>far-right movements, including world politics, conspiracy theories, COVID-19,<br>and the anti-vaccination movement. Taken all together, we perform the first<br>multilingual study on QAnon through Telegram and paint a nuanced overview of<br>the globalization of the QAnon theory.<br> %K Computer Science, Computers and Society, cs.CY,cs.SI %B WebSci '23 %P 75 - 85 %I ACM %@ 979-8-4007-0089-7

While using port 0 is not<br>allowed in most transport protocols, we see a non-negligible share of traffic<br>using port 0 in the Internet. In this study, we dissect port 0 traffic to infer<br>its possible origins and causes using five complementing flow-level and<br>packet-level datasets. We observe 73 GB of port 0 traffic in one week of IXP<br>traffic, most of which we identify as an artifact of packet fragmentation. In<br>our packet-level datasets, most traffic is originated from a small number of<br>hosts and while most of the packets have no payload, a major fraction of<br>packets containing payload belong to the BitTorrent protocol. Moreover, we find<br>unique traffic patterns commonly seen in scanning. In addition to analyzing<br>passive traces, we also conduct an active measurement campaign to study how<br>different networks react to port 0 traffic. We find an unexpectedly high<br>response rate for TCP port 0 probes in IPv4, with very low response rates with<br>other protocol types. Finally, we will be running continuous port 0<br>measurements and providing the results to the measurement community.<br> %K Computer Science, Networking and Internet Architecture, cs.NI

We show that this is partially possible in many cases due to<br>advances in software testing and the structure of P4 programs. Our insight is<br>that runtime verification can detect bugs, even those that are not detected at<br>compile-time, with machine learning-guided fuzzing. This enables a more<br>automated and real-time localization of bugs in P4 programs using software<br>testing techniques like Tarantula. Once the bug in a P4 program is localized,<br>the faulty code can be patched due to the programmable nature of P4. In<br>addition, platform-dependent bugs can be detected. From P4_14 to P4_16 (latest<br>version), our observation is that as the programmable blocks increase, the<br>patchability of P4 programs increases accordingly. To this end, we design,<br>develop, and evaluate P6 that (a) detects, (b) localizes, and (c) patches bugs<br>in P4 programs with minimal human interaction. P6 tests P4 switch<br>non-intrusively, i.e., requires no modification to the P4 program for detecting<br>and localizing bugs. We used a P6 prototype to detect and patch seven existing<br>bugs in eight publicly available P4 application programs deployed on two<br>different switch platforms: behavioral model (bmv2) and Tofino. Our evaluation<br>shows that P6 significantly outperforms bug detection baselines while<br>generating fewer packets and patches bugs in P4 programs such as switch.p4<br>without triggering any regressions.<br> %K Computer Science, Software Engineering, cs.SE,Computer Science, Learning, cs.LG,Computer Science, Networking and Internet Architecture, cs.NI

We present Flowyager, a system that is built on<br>top of existing traffic capture utilities. Flowyager generates and analyzes<br>tree data structures, that we call Flowtrees, which are succinct summaries of<br>the raw flow data available by capture utilities. Flowtrees are self-adjusted<br>data structures that drastically reduce space and transfer requirements, by 75%<br>to 95%, compared to raw flow records. Flowyager manages the storage and<br>transfers of Flowtrees, supports Flowtree operators, and provides a structured<br>query language for answering flow queries across sites and time periods. By<br>deploying a Flowyager prototype at both a large Internet Exchange Point and a<br>Tier-1 Internet Service Provider, we showcase its capabilities for networks<br>with hundreds of router interfaces. Our results show that the query response<br>time can be reduced by an order of magnitude when compared with alternative<br>data analytics platforms. Thus, Flowyager enables interactive network-wide<br>queries and offers unprecedented drill-down capabilities to, e.g., identify<br>DDoS culprits, pinpoint the involved sites, and determine the length of the<br>attack.<br> %K Computer Science, Networking and Internet Architecture, cs.NI

Nevertheless, bugs,<br>misconfigurations, faults or attacks can introduce inconsistencies that<br>undermine correct operation. Previous work in this area, however, lacks a<br>holistic methodology to tackle this problem and thus, addresses only certain<br>parts of the problem. Yet, the consistency of the overall system is only as<br>good as its least consistent part.<br> Motivated by an analogy of network consistency checking with program testing,<br>we propose to add active probe-based network state fuzzing to our consistency<br>check repertoire. Hereby, our system, PAZZ, combines production traffic with<br>active probes to continuously test if the actual forwarding path and decision<br>elements (on the data plane) correspond to the expected ones (on the control<br>plane). Our insight is that active traffic covers the inconsistency cases<br>beyond the ones identified by passive traffic. PAZZ prototype was built and<br>evaluated on topologies of varying scale and complexity. Our results show that<br>PAZZ requires minimal network resources to detect persistent data plane faults<br>through fuzzing and localize them quickly.<br> %K Computer Science, Networking and Internet Architecture, cs.NI

To take advantage of the networks' diverse paths characteristics (delay, bandwidth, and reliability) and aggregate bandwidth, we need smart strategies for choosing which interface(s) to use for what traffic. In this paper, we present an approach how to tackle this challenge as part of the Operating System (OS): With the concept of Socket Intents, applications can express what they know about their communication pattern and their preferences. Using our Socket Intents Prototype and our modified BSD Socket Interface, this information is used to choose the most appropriate path or path combination on a per message or per connection basis. We evaluate our system based on the use case of Web browsing: Using our prototype and a client-side proxy, we show the feasibility and benefits of our design. Using a flow-based simulator and a full factorial experimental design, we study a broad range of access network combinations (based on typical DSL and LTE scenarios) and real workloads (Alexa Top 100 and Top 1000 Web Sites). Our policies achieve performance benefits in more than 50% of the cases and speedups of more than factor two in 20% of the cases without adding overhead in the other cases. %K Computer Science, Networking and Internet Architecture, cs.NI

The networking<br>community is actively engaged in debating the fairness, performance, and<br>applicability of QUIC for various use cases, but these debates are centered<br>around a narrow, common theme: how does the new reliable transport built on top<br>of UDP fare in different scenarios? Support for unreliable delivery in QUIC<br>remains largely unexplored.<br> The option for delivering content unreliably, as in a best-effort model,<br>deserves the QUIC designers' and community's attention. We propose extending<br>QUIC to support unreliable streams and present a simple approach for<br>implementation. We discuss a simple use case of video streaming---an<br>application that dominates the overall Internet traffic---that can leverage the<br>unreliable streams and potentially bring immense benefits to network operators<br>and content providers. To this end, we present a prototype implementation that,<br>by using both the reliable and unreliable streams in QUIC, outperforms both TCP<br>and QUIC in our evaluations.<br> %K Computer Science, Networking and Internet Architecture, cs.NI
