Delayscan

Delayscan is a term used to describe a process or tool for measuring and analyzing delays in time-stamped data streams. It is not a single standardized product but a concept employed across various fields to identify latency issues, timing mismatches, and jitter in communications, processing pipelines, and synchronized systems.

A delayscan typically collects time-stamped events from multiple sources and computes delays between them. It constructs delay distributions, visualizes latency over time, and applies scanning methods to detect patterns or anomalies. Common techniques associated with delayscan include cross-correlation, time-difference of arrival estimates, and histogram-based analyses. The goal is to quantify delay characteristics, such as average latency, peak delays, and variability, to inform troubleshooting or optimization.

Applications of delayscan span several domains. In computer networks and streaming, it helps diagnose end-to-end latency and Quality of Service issues. In audio and video synchronization, it aids in aligning multiple streams. In sensor networks and industrial automation, it reveals timing skew between devices and stages of a workflow. In transportation and manufacturing, it can identify bottlenecks and delays in schedules or production lines.

Implementation may take the form of software libraries, monitoring dashboards, or integrated data-analysis modules. Outputs typically include latency metrics, delay distributions, jitter estimates, and anomaly reports, often exportable in common formats such as CSV or JSON and compatible with time-series databases.

Notes: the term delayscan is descriptive and not anchored to a single standard. Related concepts include latency analysis, time-of-arrival measurement, and synchronization assessment. Accurate delayscan results depend on reliable timestamping and clock synchronization across sources.
