Pushing Alias Resolution to the Limit
Taha Albakour, Oliver Gasser, Georgios Smaragdakis
In this paper, we show that utilizing multiple protocols offers a unique opportunity to improve IP alias resolution and dual-stack inference substantially. Our key observation is t…
Illuminating Router Vendor Diversity Within Providers and Along Network Paths
Taha Albakour, Oliver Gasser, Robert Beverly +1
The Internet architecture has facilitated a multi-party, distributed, and heterogeneous physical infrastructure where routers from different vendors connect and inter-operate via I…
Deep Dive into the IoT Backend Ecosystem
Said Jawad Saidi, Srdjan Matic, Oliver Gasser +2
Internet of Things (IoT) devices are becoming increasingly ubiquitous, e.g., at home, in enterprise environments, and in production lines. To support the advanced functionalities o…
AS-Level BGP Community Usage Classification
Thomas Krenc, Robert Beverly, Georgios Smaragdakis
BGP communities are a popular mechanism used by network operators for traffic engineering, blackholing, and to realize network policies and business strategies. In recent years, ma…
Third Time's Not a Charm: Exploiting SNMPv3 for Router Fingerprinting
Taha Albakour, Oliver Gasser, Robert Beverly +1
In this paper, we show that adoption of the SNMPv3 network management protocol standard offers a unique -- but likely unintended -- opportunity for remotely fingerprinting network…
Keep your Communities Clean: Exploring the Routing Message Impact of BGP Communities
Thomas Krenc, Robert Beverly, Georgios Smaragdakis
BGP communities are widely used to tag prefix aggregates for policy, traffic engineering, and inter-AS signaling. Because individual ASes define their own community semantics, many…
Exploring Network-Wide Flow Data with Flowyager
Said Jawad Saidi, Aniss Maghsoudlou, Damien Foucard +3
Many network operations, ranging from attack investigation and mitigation to traffic management, require answering network-wide flow queries in seconds. Although flow records are c…
A Haystack Full of Needles: Scalable Detection of IoT Devices in the Wild
Said Jawad Saidi, Anna Maria Mandalari, Roman Kolcun +5
Consumer Internet of Things (IoT) devices are extremely popular, providing users with rich and diverse functionalities, from voice assistants to home appliances. These functionalit…
The Lockdown Effect: Implications of the COVID-19 Pandemic on Internet Traffic
Anja Feldmann, Oliver Gasser, Franziska Lichtblau +9
Due to the COVID-19 pandemic, many governments imposed lock downs that forced hundreds of millions of citizens to stay at home. The implementation of confinement measures increased…
The Dagstuhl Beginners Guide to Reproducibility for Experimental Networking Research
Vaibhav Bajpai, Anna Brunstrom, Anja Feldmann +6
Reproducibility is one of the key characteristics of good science, but hard to achieve for experimental disciplines like Internet measurements and networked systems. This guide pro…
Beyond Counting: New Perspectives on the Active IPv4 Address Space
Philipp Richter, Georgios Smaragdakis, David Plonka +1
In this study, we report on techniques and analyses that enable us to capture Internet-wide activity at individual IP address-level granularity by relying on server logs of a large…
Opportunities in a Federated Cloud Marketplace
Hamed Haddadi, Georgios Smaragdakis, K. K. Ramakrishnan
Recent measurement studies show that there are massively distributed hosting and computing infrastructures deployed in the Internet. Such infrastructures include large data centers…
On the importance of Internet eXchange Points for today's Internet ecosystem
Nikolaos Chatzis, Georgios Smaragdakis, Anja Feldmann
Internet eXchange Points (IXPs) are generally considered to be the successors of the four Network Access Points that were mandated as part of the decommissioning of the NSFNET in 1…
Content-aware Traffic Engineering
Benjamin Frank, Ingmar Poese, Georgios Smaragdakis +2
Today, a large fraction of Internet traffic is originated by Content Providers (CPs) such as content distribution networks and hyper-giants. To cope with the increasing demand for…
