ITU-T Y.1564 requires that standard tests such as throughput, frame loss, latency, and packet jitter be run simultaneously with multiple services running at the same time. This allows for measuring the impact between services, which can affect the network's ability to maintain service-level agreement (SLA) compliance, as well as reducing the time required to test an Ethernet service.
There are two different types of tests available for the AQ1300 series testers with ITU-T Y.1564 functionality: a configuration test mode to examine the speed and burst size per contracted service and a performance test mode to measure the guaranteed bandwidth of multiple services.
In configuration test mode, the AQ1300 performs a "Ramp test", whereby the device emits a gradually increasing volume of signals (ramp) and measures the guaranteed speed and security rate, or a "burst size" test, whereby the device emits a burst of frame signals at regular intervals and measures the guaranteed burst bandwidth size and the security burst bandwidth size.
