Periodic Reporting for period 4 - ResolutioNet (Resolving the Tussle in the Internet: Mapping, Architecture, and Policy Making)
Berichtszeitraum: 2021-07-01 bis 2023-01-31
This project aims: (1) characterize the complex interactions among the various Internet stakeholders using a measurement-driven approach, (2) design and develop network systems to resolve conflicts among various Internet stakeholders , (3) enable collaborative network architectures to reach a win-win situation for all the involved parties, (4) understand cyber-threats, and (5) inform policy making about the state and health of the Internet and suggest policies to incentivize cooperation,
The project challenges our mental model about the operation and structure of the Internet. A better understanding of the Internet that this project offers will contribute to ongoing regulatory, educational, and industrial efforts towards a faster and more accessible Internet. We expect that the methodologies, tools, and results derived in this project will be material for future computer networking textbooks, but also be of great value for scientists in other scientific fields that model the Internet such as distributed systems, mathematics, political science, and economics. We also study cyberthreats and develop techniques to protect the Internet and Web.
Regarding Internet sustainability, we performed a data-driven analysis and system design towards a more sustainable Internet in light of the ever-increasing traffic demand and competitiveness in the Internet ecosystem. We developed and evaluated algorithms for incremental and sustainable upgrades of ISP networks [Transactions on Networking 2019, INFOCOM 2017] and datacenters [ANCS 2021], and performed a multi-discipline analysis of the forces that shape Internet content delivery [SIGCOMM 2021, HotNets 2021, Telecom Policy Journal 2017] and the Network Neutrality debate [CCR 2020]. We developed and operated a novel system [CoNEXT 2019] to enable the collaboration between network providers and content network providers. We also we developed techniques for geo-distributed analytic techniques [TNSM 2022] and summarized our experience and best practices for reproducibility [CCR 2019].
We studied and defended online user privacy. We performed a large-scale study to assess the compliance of ad and tracking services with the recently implemented European Union General Data Protection Regulation (GDPR), concerning the physical location of the servers and the sensitive topics that they track [IMC2018 on GDPR compliance assessment]. We also developed classifiers to identify sensitive Websites in the Web [IMC2020 on GDPR classifiers] and performed a large-scale study to assess what extent persistent cookies and trackers are present in governmental, international organisations, and COVID-19 information websites [WebSci 2022]. We also developed secure Federated Learning methods for robust classification of GDPR-related sensitive and general topics [NDSS2023]. In a parallel effort, we investigated privacy and security vulnerabilities of Internet of Things (IoT) [IMC 2022, IMC2020 on IoT detection] and IPv6 [CCR 2022].
With regards to Internet security and cyberthreats, we investigated and analyzed cyber threats towards understanding the dark web economy [IEEEAccess 2023] and mitigating cyberattacks [CACM 2023]. We also developed algorithms and techniques to detect and analyze critical Internet infrastructure failures [SIGCOMM 2017,CoNEXT 2021] and the Internet's behavior under stress [CACM 2021,IMC 2020 on COVID19, Book chapter on COVID-19, TMA 2023] towards understanding and mitigating evolving threats in an increasingly complex Internet ecosystem. We also inferred attack mitigation strategies by Internet stakeholders [IMC 2017] and efficiently mitigated Tbps-level using collaborative architectures that involve Internet infrastructure and peering providers [CCS 2021, CoNEXT 2018]. In the process, we uncovered vulnerabilities in the global routing system [IMC2018 on BGP Communities Attacks, CoNEXT 2020, IMC2021 on BGP Communities]. We investigated the propagation of software updates in end-user devices such as smartphones [IMC2020 on software updates], and studied security issues of deployed routers [IMC2021 on SNMPv3 protocol] and programmable networks [Transactions on Networking 2023, INFOCOM 2021].
