What does throughput refer to in network performance?

Throughput specifically measures the actual amount of data that successfully flows through a network point over a specified period. It is a crucial metric in network performance, as it gives a clear indication of how efficiently data is being transmitted from one point to another under real-world conditions.

This contrasts with the concept of bandwidth, which refers to the maximum capacity of a network link and indicates the highest possible rate at which data can be transmitted, assuming ideal conditions. By focusing on throughput, you can gain insights into network performance affected by factors such as congestion, quality of service, and protocol overhead, which all may result in less data being transmitted than the theoretical maximum.

Understanding throughput allows network professionals to evaluate and troubleshoot performance issues effectively, ensuring that the network meets the required service levels for applications and users. In summary, throughput provides a realistic measure of network efficiency, representing the effective performance observed over time.
