TestSute ns3-tcp-cwnd fails
Last modified: 2009-10-15 15:06:24 EDT
This is an artifact of the recent TCP patch. Unknown whether or not this is a real failure. happens on ns-regression: configured for debug; gcc version 4.2.4 (Ubuntu 4.2.4-1ubuntu4); Linux version 2.6.24-19-server reproduce with: ./waf --run "test-runner --suite=ns3-tcp-cwnd --basedir=`pwd`"
I looked at this a little bit a few days ago after I pushed the TCP patches. To just relay some information for future reference to this bug, I compared the pcap files from the old (passing) testcase and the new (failing) test case. I didn't look at every single packet in detail, but I believe they were identical (same number of packets, same time events, etc). The testcase is failing because the total number of events is less than the expected 21. It is instead 20. So the last event that the testcase refers to (the "slamming shut" of the tcp cwnd) is not occuring. I am unsure of whether or not this should actually happen.
