Network Packet Recording

Architecture

Network packet recording functions as the foundational layer for capturing raw binary data streams traversing between exchange matching engines and participant co-location servers. This process involves mirroring traffic at the switch level to ensure every datagram, including order entry requests and market data updates, remains intact for future examination. Precise timestamping during the ingestion phase allows quantitative analysts to reconstruct market events with nanosecond resolution, providing a verifiable map of liquidity flow and order book evolution.
