Latency physics: SpeedOfLightLatency computes speed-of-light-in-fibre latency floors (one-way or round-trip) and haversine great-circle distances between IBXes, metros, or raw coordinates - fully offline once the endpoints' coordinates are known.

The figures are physical lower bounds (configurable fibre refractive index and route factor), used by the peering resiliency analysis for diversity RTT floors and available directly for architecture reviews: compare the computed floor with Equinix's measured inter-metro avgLatency to see what the network delivers versus what physics allows.

    Description
    RouteFactorCalibration
    How much slower real Equinix Fabric round trips are than the straight-fibre physics floor, fitted from the metro pairs Fabric actually measures, so that an unmeasured pair can be estimated from distance with a factor the catalogue itself supports instead of a hard-coded guess.
    RouteFactorCalibration.Fit
    One fitted factor.
    RouteFactorCalibration.MeasuredPair
    One Fabric-measured metro pair.
    SpeedOfLightLatency
    Estimates network latency from geographic distance using the speed of light in optical fiber.
    SpeedOfLightLatency.Builder
    Fluent configuration for SpeedOfLightLatency.
    SpeedOfLightLatency.Mode
    Whether to report a one-way or a round-trip (RTT) figure.
