Class B was claimed as there was no significant network utilization reduction, from the average of around
20% during the UDP packet throughput test as shown in
図
65 . During the packet error test, the network
utilization dropped from 5% to 1% due to a laptop issue when a packet lost was detected.

During the test, the UDP packet error test program printed the packet number for every packet lost as well
as the total submitted packets. The total number of submitted packets during the EFT event was 60,680
packets (1526 bytes each). The number of lost packets was 100. However, there was not a single event
where two consecutive packets were lost. Therefore, every lost packet was re-submitted successfully.
