What is the purpose of network metrics?

Network metrics serve as critical indicators for evaluating the performance and efficiency of a network. By measuring aspects such as latency, throughput, packet loss, and jitter, they provide data that network engineers can analyze to ensure the network operates optimally and meets the required standards of service. This performance measurement is essential for identifying bottlenecks, understanding usage patterns, and making informed decisions regarding network upgrades or troubleshooting existing issues.

While other options involve important aspects of networking—such as aesthetics, bandwidth allocation, and access control—none directly relate to the comprehensive assessment of how well a network performs and operates. Focusing on performance and efficiency through metrics allows for the continuous improvement and reliability of network services, ultimately contributing to better user experiences and operational effectiveness.
