Result Interpretation

Firewall Rule Set Evaluation Time Complexity Calculator computes Evaluation Time Complexity Coefficient in 1 using the defined engineering formula and the input values provided. No universal acceptance threshold is defined by this calculator.

Worked Example

Verified calculation

Given:

  • Number of Firewall Rules = 500
  • Maximum Condition Depth per Rule = 2
  • Average Match Operations per Condition = 1

Expected Result:

  • Evaluation Time Complexity Coefficient = 1000
