# linkSpeedBps

[Source](https://github.com/konoe-akitoshi/shumoku/blob/main/libs/@shumoku/core/src/layout/link-utils.ts#L73)

Resolve a link's nominal speed (bits/sec). Reads per-endpoint module standards (the canonical source) and falls back to runtime \`rateBps\` when neither end has a module set. For symmetric links both endpoints return the same speed; for asymmetric links (BiDi etc.) we pick the lower of the two (conservative for utilization math).
