This tool will help you estimate the round-trip time (RTT) for data packets in your Azure network.
Azure RTT Estimator
This tool estimates the Round-trip Time (RTT) for your Azure connection based on parameters such as Latency, Throughput, Packet Size, and the Number of Connections.
How to use:
- Enter the Latency in milliseconds (ms).
- Enter the Throughput in Megabits per second (Mbps).
- Enter the Packet Size in Kilobytes (KB).
- Enter the Number of Connections.
- Click the “Calculate” button to get the estimated RTT.
How it calculates:
The calculator uses the formula to estimate the RTT as follows:
- TCP Window Size: Connections * (Throughput in KB per second) * (Latency in seconds)
- RTT Estimation: (TCP Window Size / Packet Size) * 2
Limitations:
Note that this estimator provides an approximation of RTT. Actual RTT may vary due to network conditions, routing, and other factors not accounted for in this simple model. Always perform multiple tests to get a comprehensive understanding of your network performance.
