Glossary
Short definitions for billing, networking and infrastructure—with links to in-depth articles.
95/5 method
Percentile billing model: the top 5% of traffic samples in a billing period are discarded; the highest remaining sample defines the billable rate.
Full article →CDR (Committed Data Rate)
Minimum traffic volume or rate a customer commits to pay for each billing period—protects providers against “burst-only” usage patterns.
Percentile billing
Charging based on a statistical percentile of measurements rather than absolute peak usage.
Measurement interval
How often inbound and outbound traffic is sampled—typically every five minutes in datacenter contracts.
Traffic burst
Short-lived spike in bandwidth usage (backups, updates, viral traffic) that percentile billing is designed to absorb.
Mbit/s billing
Pricing tied to a sustained megabit-per-second rate derived from measurements, not total gigabytes transferred.
