Internet Localization of Multi-Party Relay Users: Inherent Friction Between Internet Services and User Privacy
Sean Flynn, Francesco Bronzino, Paul Schmitt
Internet privacy is increasingly important on the modern Internet. Users are looking to control the trail of data that they leave behind on the systems that they interact with. Mul…
AC-DC: Adaptive Ensemble Classification for Network Traffic Identification
Xi Jiang, Shinan Liu, Saloua Naama +3
Accurate and efficient network traffic classification is important for many network management tasks, from traffic prioritization to anomaly detection. Although classifiers using p…
Enabling Personalized Video Quality Optimization with VidHoc
Xu Zhang, Paul Schmitt, Marshini Chetty +2
The emerging video applications greatly increase the demand in network bandwidth that is not easy to scale. To provide higher quality of experience (QoE) under limited bandwidth, a…
Towards Reproducible Network Traffic Analysis
Jordan Holland, Paul Schmitt, Prateek Mittal +1
Analysis techniques are critical for gaining insight into network traffic given both the higher proportion of encrypted traffic and increasing data rates. Unfortunately, the domain…
LEAF: Navigating Concept Drift in Cellular Networks
Shinan Liu, Francesco Bronzino, Paul Schmitt +5
Operational networks commonly rely on machine learning models for many tasks, including detecting anomalies, inferring application performance, and forecasting demand. Yet, model a…
Characterizing Service Provider Response to the COVID-19 Pandemic in the United States
Shinan Liu, Paul Schmitt, Francesco Bronzino +1
The COVID-19 pandemic has resulted in dramatic changes to the daily habits of billions of people. Users increasingly have to rely on home broadband Internet access for work, educat…
Traffic Refinery: Cost-Aware Data Representation for Machine Learning on Network Traffic
Francesco Bronzino, Paul Schmitt, Sara Ayoubi +3
Network management often relies on machine learning to make predictions about performance and security from network traffic. Often, the representation of the traffic is as importan…
Pretty Good Phone Privacy
Paul Schmitt, Barath Raghavan
To receive service in today's cellular architecture, phones uniquely identify themselves to towers and thus to operators. This is now a cause of major privacy violations, as operat…
Can Encrypted DNS Be Fast?
Austin Hounsel, Paul Schmitt, Kevin Borgolte +1
In this paper, we study the performance of encrypted DNS protocols and conventional DNS from thousands of home networks in the United States, over one month in 2020. We perform the…
Classifying Network Vendors at Internet Scale
Jordan Holland, Ross Teixeira, Paul Schmitt +4
In this paper, we develop a method to create a large, labeled dataset of visible network device vendors across the Internet by mapping network-visible IP addresses to device vendor…
Beyond the Trees: Resilient Multipath for Last-mile WISP Networks
Bilal Saleem, Paul Schmitt, Jay Chen +1
Expanding the reach of the Internet is a topic of widespread interest today. Google and Facebook, among others, have begun investing substantial research efforts toward expanding I…
Encryption without Centralization: Distributing DNS Queries Across Recursive Resolvers
Austin Hounsel, Paul Schmitt, Kevin Borgolte +1
Emerging protocols such as DNS-over-HTTPS (DoH) and DNS-over-TLS (DoT) improve the privacy of DNS queries and responses. While this trend towards encryption is positive, deployment…
Comparing the Effects of DNS, DoT, and DoH on Web Performance
Austin Hounsel, Kevin Borgolte, Paul Schmitt +2
Nearly every service on the Internet relies on the Domain Name System (DNS), which translates a human-readable name to an IP address before two endpoints can communicate. Today, DN…
Inferring Streaming Video Quality from Encrypted Traffic: Practical Models and Deployment Experience
Paul Schmitt, Francesco Bronzino, Sara Ayoubi +3
Inferring the quality of streaming video applications is important for Internet service providers, but the fact that most video streams are encrypted makes it difficult to do so. W…
Oblivious DNS: Practical Privacy for DNS Queries
Paul Schmitt, Anne Edmundson, Nick Feamster
Virtually every Internet communication typically involves a Domain Name System (DNS) lookup for the destination server that the client wants to communicate with. Operators of DNS r…
OCDN: Oblivious Content Distribution Networks
Anne Edmundson, Paul Schmitt, Nick Feamster +1
As publishers increasingly use Content Distribution Networks (CDNs) to distribute content across geographically diverse networks, CDNs themselves are becoming unwitting targets of…
Rangzen: Anonymously Getting the Word Out in a Blackout
Adam Lerner, Giulia Fanti, Yahel Ben-David +3
In recent years governments have shown themselves willing to impose blackouts to shut off key communication infrastructure during times of civil strife, and to surveil citizen comm…
