For the first time, manufacturers of GFR-capable switches and ATM Service Providers have a way to test conformance to this new ATM contract specification. The Agilent Technologies GFR Test Suite combines Guaranteed Frame Rate (GFR) testing capability, with extended frame-based performance metric calculations. With the ability to both analyze received streams for GFR contract conformance and generate GFR-eligible streams, the GFR Test Suite can test both shapers and policers alike. The GFR Test Suite also provides a series of frame-based performance measurements including frame latency, frame loss ratio and frame discard to paint a clearer picture of how the System Under Test (SUT) is behaving.
