The article explains why Tick‑to‑Trade (T2T) latency is critical for HFT, describes three measurement layers—application, kernel, and hardware/wire—and compares their accuracy, complexity, and use cases, then offers practical steps and metrics for beginning T2T latency monitoring.
The Network Quality Monitoring Center is a large‑scale system that deploys lightweight agents on every server to issue coordinated ICMP ping probes, a controller to generate and distribute topology‑aware PingLists, and a storage‑analysis module that aggregates latency and loss data for real‑time visualization, alerting and troubleshooting, while addressing load‑balance, ingestion concurrency, and future extensions such as UDP/TCP probes.
To accurately benchmark and reduce end-to-end latency on large live-streaming platforms, this article details practical measurement frameworks for both HTTP-FLV—using custom SEI timestamps and cloud-synced clocks—and WebRTC—leveraging RTCPeerConnection stats to dissect uplink, server, jitter, decoding, and render delays.
