The Internet Measurement Conference (IMC) is a highly selective venue for the presentation of measurement-based research in data communications. The focus of IMC 2021 will be on research that improves the practice of network measurement, illuminates some facet of an operational network, or both. We encourage authors to discuss the implications of their results on future research and/or operations. We encourage authors to discuss representativeness and limitations of their work due to coverage of their measurements across space and time. Finally, we encourage authors to validate inferences using ground truth.

IMC takes a broad view of contributions that are considered in scope for improving the practice of network measurement, including, but not limited to:

    collection and analysis of data that yield new insights about network structure and network performance (e.g., traffic, topology, routing, energy utilization, performance)
    collection and analysis of data that yield new insights about application and end-user behavior (e.g., economics, privacy, security, application interaction with protocols)
    measurement-based modeling (e.g., workloads, scaling behavior, assessment of performance bottlenecks, causality)
    methods and tools to monitor and visualize network-based phenomena
    systems and algorithms that build on measurement-based findings
    Novel methods for data collection, analysis, and storage (e.g., anonymization, querying, sharing)
    reappraisal of previous empirical network measurements and measurement-based conclusions
    descriptions of challenges and future directions the measurement community should pursue

Networks of interest include:

    Internet transit networks
    edge networks, including home networks, broadband access networks (e.g., cable, fiber), and cellular networks
    data center networks and cloud computing infrastructure
    peer-to-peer, overlay, and content distribution networks
    software-defined networks
    online social networks
    online services, platforms, and content providers
    experimental networks, prototype networks, and future Internetworks
