User-Perceived Performance

User-perceived performance of network applications is made up of a number of mainly qualitative metrics, some of which are in conflict with each other. In the case of some applications, a single metric will outweigh the others, such as responsiveness from video services or throughput for bulk transfer applications. More commonly, a combination of factors usually determines the experience of network performance for the end-user.

• Responsiveness
• Capacity and throughput
• Reliability
