1. What is Throughput?

Throughput is the rate at which data is successfully transferred over a network, typically measured in bytes per second. It's a key metric for evaluating network performance.

2. How Does the Calculator Work?

The calculator uses the throughput equation:

Where:

• \( Window\ Size \) — The amount of data that can be sent before waiting for acknowledgment (bytes)
• \( Round\ Trip\ Time \) — The time it takes for a packet to go from sender to receiver and back (seconds)

Explanation: The equation shows that throughput is directly proportional to window size and inversely proportional to latency (RTT).

3. Importance of Throughput Calculation

Details: Understanding throughput helps in network capacity planning, performance optimization, and troubleshooting network bottlenecks.

4. Using the Calculator

Tips: Enter window size in bytes and round trip time in seconds. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How does window size affect throughput?
A: Larger window sizes generally increase throughput, but may require more buffer space and can lead to congestion if not properly managed.

Q2: What factors influence round trip time?
A: RTT is affected by physical distance, network congestion, processing delays, and the number of intermediate devices.

Q3: What are typical throughput values?
A: Throughput varies greatly depending on network type - from kilobits per second for mobile networks to gigabits per second for fiber connections.

Q4: How can I improve throughput?
A: Methods include increasing window size, reducing RTT (e.g., with CDNs), optimizing protocols, and upgrading network infrastructure.

Q5: Is this the only way to calculate throughput?
A: This is a basic calculation. More complex models consider packet loss, protocol overhead, and other factors.
