Test conditions
Tester: 80-239-142-217.customer.teliacarrier.com (80.239.142.217)
[?]
Target: 88.216.91.245 (88.216.91.245)
[?]
Logfile base name: 88.216.91.245:2012-02-20-03:53:26
[?]
This report is based on a 10 Mb/s target application data rate
[?]
Warning: The section RTT is greater than the requested target RTT (56 > 20)
[?]
This report is based on a 57 ms Round-Trip-Time (RTT) to the target application
[?]
Original target RTT was: 20 ms.
[?]
The Round Trip Time for this path section is 56.000000 ms.
The Maximum Segment Size for this path section is 1320 Bytes.
[?]
Target host TCP configuration test: Warning!
[?]
Warning: TCP connection is not using RFC1323 timestamps.
[?]
Diagnosis: The target (client) is not properly configured.
[?]
Warnings reflect problems that might not affect target end-to-end performance.
[?]
The path to the tester is too long for accurate measurements.
>
Test a shorter path section or reduce the target data rate and/or RTT.
[?]
Data rate test: Fail!
[?]
The maximum data rate was 4.435098 Mb/s.
[?]
This is below the target rate (10.000000 Mb/s).
[?]
This test did not complete due to other problems with the path, target or tester.
>
Correct other problems first, and then rerun this test.
[?]
Loss rate test: Fail!
[?]
Fail: loss event rate: 0.193133% (517 packets between loss events).
[?]
Diagnosis: there is too much background (non-congested) packet loss.
[?]
The events averaged 2.777778 losses each, for a total loss rate of 0.536481%.
[?]
FYI: To get 10 Mb/s with a 1320 byte MSS on a 57 ms path the total
end-to-end loss budget is 0.136612% (732 packets between losses).
[?]
>
Locate the excess packet loss in this section of the path.
[?]
Suggestions for alternate tests
FYI: This path may pass with a less strenuous application:
[?]
Try rate=4 Mb/s, rtt=37 ms
Or if you can raise the MTU:
[?]
Try rate=4 Mb/s, rtt=258 ms, mtu=9000 bytes
Network buffering test: Warning!
[?]
This test did not complete due to other problems with the path, target or tester.
>
Correct other problems first, and then rerun this test.
[?]
Estimated queue size is at least: Pkts: 4 Bytes: 5280
This is probably an underestimate of the actual queue size.
[?]
This corresponds to a 6.300210 ms drain time.
[?]
To get 10 Mb/s with on a 57 ms path, you need 71250 bytes of buffer space.
[?]
>
Localize all path problems by testing progressively smaller sections of the full path.
[?]
Tester validation: Pass!
[?]
No internal tester problems were detected.
