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. [?]
>  See TCP tuning instructions at http://www.psc.edu/networking/projects/tcptune/ [?]
Path measurements [?]
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.
