Why do some file types have traffic multipliers?

Different file types can carry different upstream cost, bandwidth, queueing, and retry overhead, so multipliers reflect the real transfer cost.

Are multipliers the same for every provider?

No. Different upstream restrictions and transfer conditions can lead to different multiplier rules.

Einige Quellen/Routen verursachen höhere Betriebskosten. Der Multiplikator bildet das ab, um Stabilität und Verfügbarkeit zu sichern.
