This tool helps you estimate the Average Delay (AVD) and Round-Trip Time (RTT) for network communications.
How to Use the AVD RTT Estimator
To use this Accurate RTT (Round Trip Time) Estimator, please follow these steps:
- Enter a value for Alpha (α). It should be between 0.01 and 1. This is the weight given to the latest sample RTT compared to previous estimated RTT.
- Enter the current Sample RTT. This is the most recent round trip time you have measured.
- Enter the Previous Estimated RTT. This is the last calculated estimated RTT value.
- Click the Calculate button to get the new estimated RTT.
Calculation Process:
The Estimator calculates the new estimated RTT using the formula:
Estimated RTT = (1 - α) * Previous RTT + α * Sample RTT
Alpha (α): a smoothing factor, in the range 0 < α ≤ 1.
Sample RTT: the current measured round-trip time.
Previous Estimated RTT: the last estimated RTT value.
Limitations:
This calculation is dependent on the accuracy of the input values:
- If the alpha value is too high, the estimated RTT becomes very similar to the last measured RTT which may result in less smoothing.
- If the alpha value is too low, the estimated RTT changes very slowly, making it less responsive to actual network conditions.
- Values outside the allowed input ranges may produce invalid results or errors.
