Service performance test
In a service performance test, frame signals at the committed information rate (CIR) for all service
circuits (up to eight) are sent simultaneously to a network device to measure the following parameters:
• Information rate (IR)
• Frame loss (FL)
• Frame transfer delay (FTD)
• Frame delay variation (FDV)
• Availability (AVAIL)
Indicates the percentage of time (seconds) in which there are no critical errors when service circuits
are in a usable state.
In a single measurement, up to eight service circuits can be measured simultaneously.
Example of service performance test
Test time: 1 minute to 72 hours
Service number 01: Tx rate (CIR value) 1000 Mbps
Service number 02: Tx rate (CIR value) 500 Mbps
Service number 03: Tx rate (CIR value) 500 Mbps
• • •
Service number 08: Tx rate (CIR value) 1000 Mbps
