Network Readiness Assessment Calculator

Score whether a network is ready for a new service across bandwidth, latency, jitter, loss, QoS and redundancy.

About Network Readiness Assessment Calculator

Each transport characteristic is normalised onto its own weighted band against thresholds real-time services actually need, then summed. Loss is weighted most aggressively per unit because a fraction of a percent is enough to make voice and video unusable even when bandwidth is abundant. New services fail on jitter and loss far more often than on bandwidth, so an assessment that only checks megabits gives false confidence before a rollout.

Formula

Network Readiness Assessment

readiness = bandwidth ratio (30) + latency score (20) + jitter score (20) + loss score (15) + QoS (10) + redundancy (5).

bandwidth ratio
Available divided by required, capped at 30 points
latency score
Scored against a 50 ms reference

Worked example

With the default values below, Network Readiness Assessment Calculator returns Readiness Score of 75.1. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 7 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is Network Readiness Assessment calculated?

readiness = bandwidth ratio (30) + latency score (20) + jitter score (20) + loss score (15) + QoS (10) + redundancy (5). Each transport characteristic is normalised onto its own weighted band against thresholds real-time services actually need, then summed. Loss is weighted most aggressively per unit because a fraction of a percent is enough to make voice and video unusable even when bandwidth is abundant.

Why does Network Readiness Assessment matter?

New services fail on jitter and loss far more often than on bandwidth, so an assessment that only checks megabits gives false confidence before a rollout.

What values do I need to enter?

This calculator takes 7 inputs: Available bandwidth, Bandwidth the service requires, Measured one-way latency, Measured jitter, Measured packet loss, End-to-end QoS marking and queuing in place, Redundant path available. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
