Info

Methodology. This test should involve several test ports to match the DUT's port density. Ideally, the test should flood traffic to every input port of the DUT. A number of Ixia load modules will be connected to the DUT. Ixia's IxScriptMate is used to perform the RFC 2544 benchmark test. Figure 5. RFC 2544: Throughput Test — results. Results. The results of the test show the throughput rates, in frames per second, obtained for each frame size. The results also show the average throughput rates for all the trials. 10-Gigabit Ethernet Switch Performance Testing Copyright © 2004, Ixia 23
2. Testing for Latency: RFC 2544 Latency Tests Objective. To determine the latency of the DUT, and how much it varies with different frame sizes. In this test, frames are transmitted for a fixed duration. Once per second, the test tags a frame and transmits it halfway through the duration time. The test compares the tagged frame's timestamp when it was transmitted with the timestamp when it was received. The difference between the two timestamps is the latency. Setup. A minimum of two 10GE test ports will be used for this test, in conjunction with the IxScriptmate RFC2544 test. Latency will be measured in both directions. Parameters. Select the test port pairs, frame size mode and frame sizes, and number of iterations. Figure 6. RFC 2544: Latency Test — results. Methodology 1. Packets will be sent to the DUT from each 10GE load module starting with the selected minimum frame size for an interval that lasts for selected test duration. 2. The average latency is then measured. 3. These two steps will continuously repeat, using selected frame sizes every interval until it reaches the maximum frame size selected. Results. The results of the test show the latency in nanoseconds (ns) obtained for each frame size and test port pair. The results also show the average latencies across the pairs. 24 Copyright © 2004, Ixia 10-Gigabit Ethernet Switch Performance Testing
