As far as I know SYN retransmissions: with rounding they occur 1, 3, 6, 12, 24, 48, and then 64 seconds apart. I want to do this on different interval time. what is the name of this parameter?
can I control on it in android and windows?
You can only control the first retransmission with HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\ID. After this, the retransmitted SYN packets are dynamically controlled (Source: KB 170359)
Per discussion in the comments, it appears that the KB article I referenced is flawed for Windows 7; it seems that changing SYN retransmission parameters is not supported.
