Показать описание
Under the Statistics menu, there are some excellent graphs that show us the performance of TCP flows. Starting with the Stevens graph, we will look at how we can use these for troubleshooting slow file transfers.

Good presentation. Looking forward to the tcptrace graph presentation and the difference with Stevens.

Well explained. And Chris, I met a situation, FTP download, and the client sent more than 2000 duplicate ACKs to the server, with the same TCP sequence number. And after that, the client sent to the server an ACK with a much larger sequence number, then the server resume to sent the data. To be brief, the client sent excessive duplicate ACKs to the server. Did you meet that before?

So is this a fixable issue or was it just a blip that "went away" ? you said the TCP window size at the receiver end was full up. I suppose that could be down to it handling many more TCP sessions from other clients that could be the cause. Guess someone would have to check the receiving end for resources?

Sir do u have any idea to detect data exfiltration in https traffic ?
