Systems and Networking Lab

We work toward a secure, performant, and affordable Internet for everyone. Our research follows two paths: independent broadband data that lets the public measure and audit investment in connectivity, and AI-powered network operations for networks with limited infrastructure and staff.

Current projects

BQT Broadband Query Tool: an address-level broadband pricing and availability platform for reproducible analysis of market structure and affordability. TurboTest Learns when an Internet speed test has collected enough data to stop early. NetVibe A longitudinal latency platform that connects infrastructure-level performance measurements with user-level experience. Pramana A composable, domain-specific backend for empirical networking research. NetReplica A bottleneck-aware emulation framework for controlled experimentation and network data generation. NetGent An agentic workflow automation system that compiles high-level specifications into deterministic, reusable execution pipelines. netUnicorn A data-collection platform for distributed orchestration across heterogeneous environments; adopted as a reproducibility substrate. netFound A network foundation model that learns spatial, temporal, and hierarchical structure directly from packet-level telemetry. NetBurst Event-centric forecasting of bursty, intermittent network time series. Intrinsic Evaluation Framework A representation-level method to validate network foundation models, which separates embedding quality from downstream task artifacts. Trustee An interpretability framework for learning-based network systems.
