Amazon EC2 now provides additional network performance metrics to help customers gain more insights into instance network performance. This visibility helps customers proactively resolve application performance issues and right size instance fleets based on desired network performance. Latency, for example, would be great to analyze if you want to increase your network speed, but so might bandwidth usage. This is not a sound method for accurately measuring performance, particularly at high speeds. Performance can also be modeled and simulated instead of measured; one example of this is using state transition diagrams to model queuing performance or to use a Network Simulator. Top 10 call center metrics Metric Acronym Definition Application Tips about using this metric Service level SL or SVL Percentage of calls (X%) answered with in Y seconds. Companies that rely on background tests hidden inside of other apps to measure speed only send small amounts of data back and forth. ��y�u�X��a��> �p��ZGK�*�x}ۗF� @"===$=��V�G}{�� M+�Y�zch�h�8 QoS and network performance metrics and measurement methods; Part 3: Network performance metrics and measurement methods in IP networks. With the understanding that network performance entails the quality of service being provided by a network in its entirety; one is faced with analyzing the numerous parameters and components that are enveloped in a network before being able to provide an assessment of such network. Considering the complexity of modern-day wireless networks; opting for manual approaches, a thorough evaluation is almost impossible and will be utterly tedious to process and finalize. Timothy A. Zimmerman . Networks: Performance Measures 5 Performance Metrics (General Definitions) • Utilization :: the percentage of time a device is busy servicing a “customer”.
