  • What does the 95% rule mean?

    The bandwidth of stepping stone AG will be calculated with the 95%-rule.The 95%-rule is a common standard.

    Calculation of the 95%-rule

    When you have ordered a bandwidth of 1 Megabit/s and are connected to a 100 Megabit/s line, the Committed Data Rate (CDR) is 1 Megabit/s with a burst rate of 100 Megabit/s. The Committed Data Rate will be invoiced independently of the usage, as this bandwidth is fixed reserved for you. The burst rate of 100 Megabit/s is “best effort” and will be invoiced according to the 95%-rule, which is calculated as follows:

    Die Bandbreite wird alle 5 Minuten gemessen. Damit finden monatlich 8640 Messungen statt.

    Damit dürfen Sie ohne Kostenfolge die vereinbarte Bandbreite 432 Mal pro Monat überschreiten. Mit anderen Worten ausgedrückt: Sie dürfen während 36 Stunden pro Monat die abonnierte Bandbreite ohne Kostenfolge überschreiten.
