QoS and network performance metrics and measurement methods; Part 3: Network performance metrics and measurement methods in IP networks. Network Performance Monitor uses synthetic transactions to calculate network performance metrics like packet loss and link latency. Today’s networks have evolved and become more complex to manage. By logging in as if you're a user and exercising the same functionality the users do, you'll get accurate measurements. To understand this concept better, consider a Network Performance Monitor agent connected to one end of a network link. Five new metrics provide customers visibility when their instances exceed network allowances defined by AWS. network performance and quality metrics, such as download speed, upload speed, latency, packet loss, jitter and other indicators of network conditions. The network performance metrics being measured for wireless and wired broadband were throughput (download and upload speeds), network latency and packet loss. 0000003060 00000 n A Performance Metrics Scorecard Based Approach to Intrusion Detection System Evaluation for Wireless Network .
