This work<br>contributes to research efforts to detect and understand hateful content on the<br>Web by undertaking a multimodal analysis of Antisemitism and Islamophobia on<br>4chan's /pol/ using OpenAI's CLIP. This large pre-trained model uses the<br>Contrastive Learning paradigm. We devise a methodology to identify a set of<br>Antisemitic and Islamophobic hateful textual phrases using Google's Perspective<br>API and manual annotations. Then, we use OpenAI's CLIP to identify images that<br>are highly similar to our Antisemitic/Islamophobic textual phrases. By running<br>our methodology on a dataset that includes 66M posts and 5.8M images shared on<br>4chan's /pol/ for 18 months, we detect 573,513 posts containing 92K<br>Antisemitic/Islamophobic images and 246K posts that include 420 hateful<br>phrases. Among other things, we find that we can use OpenAI's CLIP model to<br>detect hateful content with an accuracy score of 0.84 (F1 score = 0.58). Also,<br>we find that Antisemitic/Islamophobic imagery is shared in 2x more posts on<br>4chan's /pol/ compared to Antisemitic/Islamophobic textual phrases,<br>highlighting the need to design more tools for detecting hateful imagery.<br>Finally, we make publicly available a dataset of 420 Antisemitic/Islamophobic<br>phrases and 92K images that can assist researchers in further understanding<br>Antisemitism/Islamophobia and developing more accurate hate speech detection<br>models.<br> %K cs.SI,Computer Science, Computers and Society, cs.CY

To mitigate<br><br><br><br>this adverse effect, mainstream social media platforms employed soft moderation<br><br><br><br>interventions (i.e., warning labels) on potentially harmful posts. Despite the<br><br><br><br>recent popularity of these moderation interventions, we lack empirical analyses<br><br><br><br>aiming to uncover how these warning labels are used in the wild, particularly<br><br><br><br>during challenging times like the COVID-19 pandemic. In this work, we analyze<br><br><br><br>the use of warning labels on TikTok, focusing on COVID-19 videos. First, we<br><br><br><br>construct a set of 26 COVID-19 related hashtags, then we collect 41K videos<br><br><br><br>that include those hashtags in their description. Second, we perform a<br><br><br><br>quantitative analysis on the entire dataset to understand the use of warning<br><br><br><br>labels on TikTok. Then, we perform an in-depth qualitative study, using<br><br><br><br>thematic analysis, on 222 COVID-19 related videos to assess the content and the<br><br><br><br>connection between the content and the warning labels. Our analysis shows that<br><br><br><br>TikTok broadly applies warning labels on TikTok videos, likely based on<br><br><br><br>hashtags included in the description. More worrying is the addition of COVID-19<br><br><br><br>warning labels on videos where their actual content is not related to COVID-19<br><br><br><br>(23% of the cases in a sample of 143 English videos that are not related to<br><br><br><br>COVID-19). Finally, our qualitative analysis on a sample of 222 videos shows<br><br><br><br>that 7.7% of the videos share misinformation/harmful content and do not include<br><br><br><br>warning labels, 37.3% share benign information and include warning labels, and<br><br><br><br>that 35% of the videos that share misinformation/harmful content (and need a<br><br><br><br>warning label) are made for fun. Our study demonstrates the need to develop<br><br><br><br>more accurate and precise soft moderation systems, especially on a platform<br><br><br><br>like TikTok that is extremely popular among people of younger age.<br><br><br><br> %K cs.SI,Computer Science, Computers and Society, cs.CY

To support the growing number of users and their increasing demands,<br>operators have to continuously scale their network footprint -- e.g., by<br>joining Internet Exchange Points -- and adopt relevant technologies -- such as<br>IPv6. IPv6, however, has a vastly larger address space compared to its<br>predecessor, which allows for new kinds of attacks on the Internet routing<br>infrastructure.<br> In this paper, we present Kirin: a BGP attack that sources millions of IPv6<br>routes and distributes them via thousands of sessions across various IXPs to<br>overflow the memory of border routers within thousands of remote ASes. Kirin's<br>highly distributed nature allows it to bypass traditional route-flooding<br>defense mechanisms, such as per-session prefix limits or route flap damping. We<br>analyze the theoretical feasibility of the attack by formulating it as a<br>Integer Linear Programming problem, test for practical hurdles by deploying the<br>infrastructure required to perform a small-scale Kirin attack using 4 IXPs, and<br>validate our assumptions via BGP data analysis, real-world measurements, and<br>router testbed experiments. Despite its low deployment cost, we find Kirin<br>capable of injecting lethal amounts of IPv6 routes in the routers of thousands<br>of ASes.<br> %K Computer Science, Networking and Internet Architecture, cs.NI

MPTCP has been<br>under active development since its standardization in 2013, and more recently<br>in February 2020, MPTCP was upstreamed to the Linux kernel. In this paper, we<br>provide an in-depth analysis of MPTCPv0 in the Internet and the first analysis<br>of MPTCPv1 to date. We probe the entire IPv4 address space and an IPv6 hitlist<br>to detect MPTCP-enabled systems operational on port 80 and 443. Our scans<br>reveal a steady increase in MPTCPv0-capable IPs, reaching 13k+ on IPv4<br>(2$\times$ increase in one year) and 1k on IPv6 (40$\times$ increase). MPTCPv1<br>deployment is comparatively low with $\approx$100 supporting hosts in IPv4 and<br>IPv6, most of which belong to Apple. We also discover a substantial share of<br>seemingly MPTCP-capable hosts, an artifact of middleboxes mirroring TCP<br>options. We conduct targeted HTTP(S) measurements towards select hosts and find<br>that middleboxes can aggressively impact the perceived quality of applications<br>utilizing MPTCP. Finally, we analyze two complementary traffic traces from<br>CAIDA and MAWI to shed light on the real-world usage of MPTCP. We find that<br>while MPTCP usage has increased by a factor of 20 over the past few years, its<br>traffic share is still quite low.<br> %K Computer Science, Networking and Internet Architecture, cs.NI

Specifically, by<br>sending unsolicited and unauthenticated SNMPv3 requests, we obtain detailed<br>information about the configuration and status of network devices including<br>vendor, uptime, and the number of restarts. More importantly, the reply<br>contains a persistent and strong identifier that allows for lightweight<br>Internet-scale alias resolution and dual-stack association. By launching active<br>Internet-wide SNMPv3 scan campaigns, we show that our technique can fingerprint<br>more than 4.6 million devices of which around 350k are network routers. Not<br>only is our technique lightweight and accurate, it is complementary to existing<br>alias resolution, dual-stack inference, and device fingerprinting approaches.<br>Our analysis not only provides fresh insights into the router deployment<br>strategies of network operators worldwide, but also highlights potential<br>vulnerabilities of SNMPv3 as currently deployed.<br> %K Computer Science, Networking and Internet Architecture, cs.NI

Because of this promise, the platform become<br>popular among users who were suspended on mainstream social networks for<br>violating their terms of service, as well as those fearing censorship. In<br>particular, the service was endorsed by several conservative public figures,<br>encouraging people to migrate from traditional social networks. After the<br>storming of the US Capitol on January 6, 2021, Parler has been progressively<br>deplatformed, as its app was removed from Apple/Google Play stores and the<br>website taken down by the hosting provider.<br> This paper presents a dataset of 183M Parler posts made by 4M users between<br>August 2018 and January 2021, as well as metadata from 13.25M user profiles. We<br>also present a basic characterization of the dataset, which shows that the<br>platform has witnessed large influxes of new users after being endorsed by<br>popular figures, as well as a reaction to the 2020 US Presidential Election. We<br>also show that discussion on the platform is dominated by conservative topics,<br>President Trump, as well as conspiracy theories like QAnon.<br> %K cs.SI,Computer Science, Computers and Society, cs.CY, Physics, Physics and Society, physics.soc-ph

Traditionally, such<br>efficiency-related questions were tackled only at the level of the overall<br>system, and in a peer-to-peer (P2P) setting where miners directly connect to<br>one another. Despite it being common today for miners to pool compute<br>capacities in a mining pool managed by a centralized coordinator, efficiency in<br>such a coordinated setting has barely been studied.<br> In this paper, we propose a simple model of a proof-of-work blockchain with<br>latencies for both the P2P and the coordinated settings. We derive a<br>closed-form expression for the efficiency in the coordinated setting with an<br>arbitrary number of miners and arbitrary latencies, both for the overall system<br>and for each individual miner. We leverage this result to show that<br>inequalities arise from variability in the delays, but that if all miners are<br>equidistant from the coordinator, they have equal efficiency irrespective of<br>their compute capacities. We then prove that, under a natural consistency<br>condition, the overall system efficiency in the P2P setting is higher than that<br>in the coordinated setting. Finally, we perform a simulation-based study to<br>demonstrate that even in the P2P setting delays between miners introduce<br>inequalities, and that there is a more complex interplay between delays and<br>compute capacities.<br> %K Computer Science, Cryptography and Security, cs.CR

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

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

In this paper, we propose a framework to study fact checking<br>efforts using Google Trends, a signal that captures search interest over topics<br>on the world's largest search engine. Our framework consists of extracting<br>claims from fact checking efforts, linking such claims with knowledge graph<br>entities, and estimating the online attention they receive. We use this<br>framework to study a dataset of 879 COVID-19-related fact checks done in 2020<br>by 81 international organizations. Our findings suggest that there is often a<br>disconnect between online attention and fact checking efforts. For example, in<br>around 40% of countries where 10 or more claims were fact checked, half or more<br>than half of the top 10 most popular claims were not fact checked. Our analysis<br>also shows that claims are first fact checked after receiving, on average, 35%<br>of the total online attention they would eventually receive in 2020. Yet, there<br>is a big variation among claims: some were fact checked before receiving a<br>surge of misinformation-induced online attention, others are fact checked much<br>later. Overall, our work suggests that the incorporation of online attention<br>signals may help organizations better assess and prioritize their fact checking<br>efforts. Also, in the context of international collaboration, where claims are<br>fact checked multiple times across different countries, online attention could<br>help organizations keep track of which claims are "migrating" between different<br>countries.<br> %K Computer Science, Computers and Society, cs.CY,cs.SI

Previous work suggests that, within<br>mainstream platforms, community-level moderation is effective in mitigating the<br>harm caused by the moderated communities. It is, however, unclear whether these<br>results also hold when considering the broader Web ecosystem. Do toxic<br>communities continue to grow in terms of user base and activity on their new<br>platforms? Do their members become more toxic and ideologically radicalized? In<br>this paper, we report the results of a large-scale observational study of how<br>problematic online communities progress following community-level moderation<br>measures. We analyze data from r/The_Donald} and r/Incels, two communities that<br>were banned from Reddit and subsequently migrated to their own standalone<br>websites.

In spite of that, users in one of<br>the studied communities (r/The_Donald) showed increases in signals associated<br>with toxicity and radicalization, which justifies concerns that the reduction<br>in activity may come at the expense of a more toxic and radical community.<br>Overall, our results paint a nuanced portrait of the consequences of<br>community-level moderation and can inform their design and deployment.<br> %K Computer Science, Computers and Society, cs.CY

One<br>community that has come into the spotlight for sharing and publishing hateful<br>content are the so-called Involuntary Celibates (Incels), a loosely defined<br>movement ostensibly focusing on men's issues, who have often been linked to<br>misogynistic views.<br> In this paper, we set out to analyze the Incel community on YouTube by<br>focusing on the evolution of this community over the last decade and<br>understanding whether YouTube's recommendation algorithm steers users towards<br>Incel-related videos. We collect videos shared on Incel-related communities<br>within Reddit, and perform a data-driven characterization of the content posted<br>on YouTube. Among other things, we find that the Incel community on YouTube is<br>getting traction and that during the last decade the number of Incel-related<br>videos and comments rose substantially. Also, we quantify the probability that<br>a user will encounter an Incel-related video by virtue of YouTube's<br>recommendation algorithm. Within five hops when starting from a<br>non-Incel-related video, this probability is 1 in 5, which is alarmingly high<br>as such content is likely to share toxic and misogynistic views.<br> %K Computer Science, Computers and Society, cs.CY

Since content on<br>YouTube is generated by its users, the platform is particularly vulnerable to<br>misinformative and conspiratorial videos. Even worse, the role played by<br>YouTube's recommendation algorithm in unwittingly promoting questionable<br>content is not well understood, and could potentially make the problem even<br>worse. This can have dire real-world consequences, especially when<br>pseudoscientific content is promoted to users at critical times, e.g., during<br>the COVID-19 pandemic.<br> In this paper, we set out to characterize and detect pseudoscientific<br>misinformation on YouTube. We collect 6.6K videos related to COVID-19, the flat<br>earth theory, the anti-vaccination, and anti-mask movements; using<br>crowdsourcing, we annotate them as pseudoscience, legitimate science, or<br>irrelevant. We then train a deep learning classifier to detect pseudoscientific<br>videos with an accuracy of 76.1%. Next, we quantify user exposure to this<br>content on various parts of the platform (i.e., a user's homepage, recommended<br>videos while watching a specific video, or search results) and how this<br>exposure changes based on the user's watch history. We find that YouTube's<br>recommendation algorithm is more aggressive in suggesting pseudoscientific<br>content when users are searching for specific topics, while these<br>recommendations are less common on a user's homepage or when actively watching<br>pseudoscientific videos. Finally, we shed light on how a user's watch history<br>substantially affects the type of recommended videos.<br> %K Computer Science, Computers and Society, cs.CY,cs.SI

Among these, the QAnon conspiracy theory has emerged in 2017 on<br>4chan, broadly supporting the idea that powerful politicians, aristocrats, and<br>celebrities are closely engaged in a global pedophile ring. At the same time,<br>governments are thought to be controlled by "puppet masters," as democratically<br>elected officials serve as a fake showroom of democracy.<br> In this paper, we provide an empirical exploratory analysis of the QAnon<br>community on Voat.co, a Reddit-esque news aggregator, which has recently<br>captured the interest of the press for its toxicity and for providing a<br>platform to QAnon followers. More precisely, we analyze a large dataset from<br>/v/GreatAwakening, the most popular QAnon-related subverse (the Voat equivalent<br>of a subreddit) to characterize activity and user engagement. To further<br>understand the discourse around QAnon, we study the most popular named entities<br>mentioned in the posts, along with the most prominent topics of discussion,<br>which focus on US politics, Donald Trump, and world events. We also use<br>word2vec models to identify narratives around QAnon-specific keywords, and our<br>graph visualization shows that some of QAnon-related ones are closely related<br>to those from the Pizzagate conspiracy theory and "drops" by "Q." Finally, we<br>analyze content toxicity, finding that discussions on /v/GreatAwakening are<br>less toxic than in the broad Voat community.<br> %K Computer Science, Computers and Society, cs.CY

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

In the face of the projected catastrophic consequences, many countries<br>have enacted social distancing measures in an attempt to limit the spread of<br>the virus. Under these conditions, the Web has become an indispensable medium<br>for information acquisition, communication, and entertainment. At the same<br>time, unfortunately, the Web is being exploited for the dissemination of<br>potentially harmful and disturbing content, such as the spread of conspiracy<br>theories and hateful speech towards specific ethnic groups, in particular<br>towards Chinese people since COVID-19 is believed to have originated from<br>China.<br> In this paper, we make a first attempt to study the emergence of Sinophobic<br>behavior on the Web during the outbreak of the COVID-19 pandemic. We collect<br>two large-scale datasets from Twitter and 4chan's Politically Incorrect board<br>(/pol/) over a time period of approximately five months and analyze them to<br>investigate whether there is a rise or important differences with regard to the<br>dissemination of Sinophobic content. We find that COVID-19 indeed drives the<br>rise of Sinophobia on the Web and that the dissemination of Sinophobic content<br>is a cross-platform phenomenon: it exists on fringe Web communities like<br>\dspol, and to a lesser extent on mainstream ones like Twitter. Also, using<br>word embeddings over time, we characterize the evolution and emergence of new<br>Sinophobic slurs on both Twitter and /pol/. Finally, we find interesting<br>differences in the context in which words related to Chinese people are used on<br>the Web before and after the COVID-19 outbreak: on Twitter we observe a shift<br>towards blaming China for the situation, while on /pol/ we find a shift towards<br>using more (and new) Sinophobic slurs.<br> %K cs.SI,Computer Science, Computers and Society, cs.CY

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

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

These accounts often use images and memes, along with textual<br>content, in order to increase the engagement and the credibility of their<br>posts.<br> In this paper, we present the first study of images shared by state-sponsored<br>accounts by analyzing a ground truth dataset of 1.8M images posted to Twitter<br>by accounts controlled by the Russian Internet Research Agency. First, we<br>analyze the content of the images as well as their posting activity. Then,<br>using Hawkes Processes, we quantify their influence on popular Web communities<br>like Twitter, Reddit, 4chan's Politically Incorrect board (/pol/), and Gab,<br>with respect to the dissemination of images. We find that the extensive image<br>posting activity of Russian trolls coincides with real-world events (e.g., the<br>Unite the Right rally in Charlottesville), and shed light on their targets as<br>well as the content disseminated via images. Finally, we show that the trolls<br>were more effective in disseminating politics-related imagery than other<br>images.<br> %K cs.SI,Computer Science, Computers and Society, cs.CY

The Internet, however, is not optimized for latency. We thus<br>explore the design of cost-effective wide-area networks that move data over<br>paths very close to great-circle paths, at speeds very close to the speed of<br>light in vacuum. Our cISP design augments the Internet's fiber with free-space<br>wireless connectivity. cISP addresses the fundamental challenge of<br>simultaneously providing low latency and scalable bandwidth, while accounting<br>for numerous practical factors ranging from transmission tower availability to<br>packet queuing. We show that instantiations of cISP across the contiguous<br>United States and Europe would achieve mean latencies within 5% of that<br>achievable using great-circle paths at the speed of light, over medium and long<br>distances. Further, we estimate that the economic value from such networks<br>would substantially exceed their expense.<br> %K Computer Science, Networking and Internet Architecture, cs.NI

But a simple computation of<br>shortest-path lengths through the conduits in the InterTubes map suggests that<br>the conversion factor for all pairs of the 120 largest population centers in<br>the U.S.\ could be reduced from 2.1 to 1.3, in the median, even using less than<br>half of the links. To determine whether an overlay network could be used to<br>provide shortest paths, and how well it would perform, we used the diverse<br>server deployment of a CDN to measure latency across individual conduits. We<br>were surprised to find, however, that latencies are sometimes much higher than<br>would be predicted by conduit length alone. To understand why, we report<br>findings from our analysis of network latency data from the backbones of two<br>Tier-1 ISPs, two scientific and research networks, and the recently built fiber<br>backbone of a CDN.<br> %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

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
