NetEye — Near-Switch Network Telemetry

Hybrid telemetry systems trade accuracy against the number of queries they can serve concurrently, because they iteratively refine a single stream.

Approach. Replay a near-switch window through every query instead, which removes the contention that forces the tradeoff — sustained across 15+ concurrent queries.

Making replay affordable. A Delta + Huffman + LZ78 compression pipeline on FPGA cuts header storage substantially, and moving monitoring logic near-switch drops data-plane update latency by more than an order of magnitude.

My role: system design and FPGA compression pipeline.

Stack: P4 / programmable data plane, FPGA prototyping, C++, Python.
