Network Performance

Network performance encompasses the qualitative and quantitative measures used to evaluate and optimize how effectively a computer network transmits data between points. It is fundamental to ensuring reliable digital communications and services.

Key Metrics

Speed Metrics

• Bandwidth - Maximum data transfer rate
• Throughput - Actual data transfer rate achieved
• Latency - Time delay between sending and receiving data
• Round-trip Time - Total time for data to travel to destination and back

Reliability Metrics

• Packet Loss - Percentage of data packets that fail to reach their destination
• Jitter - Variation in packet delay
• Error Rate - Frequency of corrupted data transmission
