I have a question about how linux's TCP stack behaves. I apologize if this is not the right place to ask this question and please redirect me. When a TCP end point (A) sends x bytes of data to the other end point (B), does B immediately ACK the received bytes or will it do so only when the data is passed to the upper layer ? Thanks Thomas
