TCP flow control RRS feed

  • Question

  • Hi,
    I am trying to understand TCP windowing. When I do tests with IPERF or with a FTP server/client, I cannot notice the slow start and congestion avoidance. During the whole transfer only packets of 2 or 3 segment are sent and acknowledged despite there are no loss or checksum errors, end the window value, on both sides, are set to 65535.
    Up to me I should see an increasing segment number until the network limit is reached, ...
    Can somebody try to explain me what is happening ?
    Thanks a lot.
