Industrial Network Bandwidth at 72% link uptime: a worked example

Suppose link uptime falls to 72%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate available industrial network bandwidth from raw link speed in Mbps, planned operating share of the period, link uptime, and the share of bandwidth left after control protocol and management overhead.

The inputs for this scenario

  • Raw link speed: 1,000 Mbps (held at the documented default)
  • Planned operating share of the link: 1 fraction (held at the documented default)
  • Link uptime: 72 % (the input this scenario stresses; the baseline uses 99.9)
  • Bandwidth left after protocol and management overhead: 50 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross network bandwidth = raw link speed × planned operating share.
  • Usable network bandwidth works out to 360 Mbps at these inputs, and this is the headline figure for the scenario.
  • Gross network bandwidth works out to 1,000 Mbps at these inputs.
  • Link downtime loss works out to 280 Mbps at these inputs.
  • Protocol and management overhead loss works out to 360 Mbps at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where link uptime sits at 99.9% and the headline result is 500 Mbps, this scenario comes in 27.93% below the baseline at 360 Mbps.
  • It computes usable network bandwidth by trimming the raw link speed for the planned operating share, link uptime and the share remaining after protocol and management overhead. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Usable network bandwidth: 360 Mbps (headline result)
  • Gross network bandwidth: 1,000 Mbps
  • Link downtime loss: 280 Mbps
  • Protocol and management overhead loss: 360 Mbps
