In the registry of Windows XP can find the following options to enable optimizations for TCP/ IP:

- MSS;
- TCP Rx Window Size;
- SACK (Selective Acknowledgment);
- ECN (Explicit Congestion Notification);
- TCP Window Scaling;
- TCP Timestamping;
- PMTU Discovery;
- TCP Fast Retransmit;
- TCP Fast Recovery;
- Delayed ACK.

For example, under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\interfaceGUID on parameter IPAddress [REG_MULTI_SZ] can find the interface and configure a specific network card.

I can manipulate the values ​​of the parameters programmatically and see the results.

I am interested in a list of similar parameters in Linux Mandriva. And yet - can I change it from Java code?

    Have you simply tried running `man tcp` on your system? It gives you a list of options for TCP/IP stack and explanations for them. You can also look at [this website](http://drupal.star.bnl.gov/STAR/blog-entry/jeromel/2009/feb/18/tcp-parameters-linux-kernel) – Karlson Jan 17 '13 at 16:46
