What is the purpose of using a network testing tool like IPerf?

Using a network testing tool like IPerf serves the primary purpose of measuring network throughput. This tool is designed to assess the maximum achievable bandwidth on a network link by generating TCP and UDP data streams and measuring the amount of data successfully sent within a specific time frame.

When network engineers or administrators need to evaluate the performance of their network or troubleshoot issues, they require reliable data on how much information can be transmitted over the network under various conditions. IPerf provides this insight by allowing users to test different configurations, such as varying the number of parallel streams, changing the buffer sizes, or testing with different protocols.

By leveraging IPerf's capabilities, stakeholders can make informed decisions about network performance improvements, capacity planning, and identifying bottlenecks, ensuring optimal network operations.
