"Violation" is probably a bit on the harsh side (after all, it says "should"), but here goes (wireshark/libpcap format):
The trace has been collected on 10.208.9.87. After one ACK plus five duplicates, a retransmission is triggered -- but it takes more than 200 ms, so that would be an ordinary retransmission. The original trace is (much) longer, but I've cut it down to keep the mail small. If required, I can provide more.


Thanks,

A.
