Test conditions
Tester: 80-239-142-217.customer.teliacarrier.com (80.239.142.217) [?]
Target: HSI-KBW-091-089-176-219.hsi2.kabel-badenwuerttemberg.de (91.89.176.219) [?]
Logfile base name: HSI-KBW-091-089-176-219.hsi2.kabel-badenwuerttemberg.de:2012-02-21-13:24:49 [?]
This report is based on a 10 Mb/s target application data rate [?]
Warning: The section RTT is greater than the requested target RTT (26 > 20) [?]
This report is based on a 27 ms Round-Trip-Time (RTT) to the target application [?]
Original target RTT was: 20 ms. [?]
The Round Trip Time for this path section is 26.000000 ms.
The Maximum Segment Size for this path section is 1460 Bytes. [?]
Target host TCP configuration test: Warning! [?]
Warning: TCP connection is not using RFC1323 timestamps. [?]
The maximum receiver window (255k) is too small for some tests, but sufficient for the target application. [?]
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: Pass! [?]
Pass data rate check: maximum data rate was 33.520728 Mb/s [?]
Loss rate test: Pass! [?]
Pass: measured loss rate 0.001301% (76865 packets between loss events). [?]
FYI: To get 10 Mb/s with a 1460 byte MSS on a 27 ms path the total end-to-end loss budget is 0.167224% (598 packets between losses). [?]
Suggestions for alternate tests
FYI: This path may even pass with a more strenuous application: [?]
    Try rate=10 Mb/s, rtt=226 ms
    Try rate=33 Mb/s, rtt=67 ms
Or if you can raise the MTU: [?]
    Try rate=10 Mb/s, rtt=1397 ms, mtu=9000 bytes
    Try rate=33 Mb/s, rtt=416 ms, mtu=9000 bytes
Network buffering test: Pass! [?]
This test did not complete due to other problems with the path, target or tester.
>  Correct other problems first, and then rerun this test. [?]
Pass: The network bottleneck has sufficient buffering (queue space) in routers and switches. [?]
Estimated queue size is at least: Pkts: 77 Bytes: 112420
This is probably an underestimate of the actual queue size. [?]
This corresponds to a 31.029480 ms drain time. [?]
To get 10 Mb/s with on a 27 ms path, you need 33750 bytes of buffer space. [?]
The network path passed all tests! [?]
Tester validation: Pass! [?]
No internal tester problems were detected.
