network throughput, transfer time, bandwidth sharing, packet rate and data-volume calculators
Turn network rates into practical transfer estimates
Estimate transfer time, shared bandwidth, data volume and packet rates from your own network assumptions.
Tools
Transfer Time
Estimate transfer duration from data size and sustained throughput.
Open →ToolsBandwidth per Active User
Split a link rate equally across active users as a simple scenario.
Open →ToolsDaily Data Volume
Estimate data transferred from a sustained rate over a number of hours.
Open →ToolsPacket Rate
Estimate packets per second from bit rate and average packet size.
Open →ToolsLink Utilization
Compare measured traffic with link capacity.
Open →Guides
Rate and data volume are different measurements
Throughput describes data per unit time while volume describes accumulated data.
GuidesUse sustained throughput for transfer estimates
A nominal interface rate can be higher than a real end-to-end transfer rate.
GuidesBandwidth sharing is a scenario, not a guarantee
Equal division is a simple model for multiple active users.
GuidesEstimate packet rate from average packet size
Packet-processing load depends on packet count as well as bit rate.
GuidesInterpret link utilization carefully
Average utilization can hide short peaks.
