Comprehensive Network Insight for Resilient Infrastructures

August 2024 – August 2026

Objective
This research aims to develop network monitoring technologies that provide deep, real-time insights into network activity. It focuses on designing in-hardware algorithms and tailored analysis tools to detect and analyze critical factors, including security intrusions, network anomalies, and root causes of failures.

Background
Computer networks are vital to the operation of modern industries and society. Failures and security breaches can range from costly inconveniences to catastrophes. For this reason, networks are continuously monitored to ensure reliability.

Unfortunately, the high speeds of modern networks make comprehensive monitoring difficult, leaving blind spots that hinder effective analysis. Achieving fine-grained, real-time traffic analysis could transform how intrusions are detected and failures are mitigated, enabling faster responses and enhancing network resilience.

About the Digital Futures Postdoc Fellow
Jonatan Langlet is a researcher with expertise in on-hardware monitoring algorithms and data structures. He earned his PhD in computer science from Queen Mary University of London, during which he focused on high-speed data collection, probabilistic streaming data analysis, and in-network artificial intelligence. His research interests span network programmability, systems, and algorithms, particularly on real-world deployability.
