I was wondering if anyone knows the timeout for delayed ACK in the kernel 2.4.26? I am using a wireless network and I used ethereal to capture my packets. I noticed many steps in the graph and I feel it is the timeout of the delayed ACK. I was wondering if anyone knows what it is set to or if there is a set number of packets? The delayed ack works fine throughout a transfer I get 2 packets in and one ack back out. After an amount of time(~4.7sec) I get steps. After a while it catches back up and goes on normally. It repeats many times throughout the transfer.
