System Recovery
The system recovery time is the time the network takes to stop losing frames when the frame rate is
reduced from a stressed to a normal state. For a period specified at set up, MGig1 will generate traffic at
a rate that is higher than the network can support, i.e. greater than the rate calculated at the throughput
test. This causes the network to lose frames. Then, the traffic is reduced to less than the pre-determined
throughput. The time between the drop in frame rate to the last lost frame is averaged over a user
specified number of test runs for each frame size.
The range for each variable is as follows:
 Repetitions – 1 to 100. The number of
test runs.
 Duration – 1 to 300. Period, in seconds,
that excess traffic is generated.

MGig1 presents the System Recovery test results
as a table (Fig 67) that lists system recovery time in
µs for each frame size tested. The information rate
shown is the rate MGig1 transmits in excess of
maximum throughput.
