InvisiFlow is a communication substrate designed to silently collect network telemetry data. Unlike traditional systems that push telemetry packets to collectors along the shortest path, InvisiFlow dynamically identifies and utilizes spare network capacity. By leveraging opportunistic sending and congestion gradients, it effectively reduces both the telemetry data loss rate and the overhead on user traffic.
Our paper will appear in NSDI 2025.
