Ethernet Tester Analyzer 37

RFC 2544 Methodology

Back-to-back

The test allows estimating the time during which the DUT is capable to

manage the maximum load.

The analyzer sends a burst of frames with minimum interframe gap to the

DUT and then counts the number of frames forwarded by the DUT. If the

count of transmitted frames is equal to the number of frames forwarded,

the time of transmission is being increased and the test is being rerun until

there are two trials succeeded with no frame lost. If the number of

forwarded frames is less than the number of transmitted ones, the time of

transmission is being reduced and the test is being rerun.
