Protocol Stack | Description |
TCP Settings |
|
Send RSTs | Click Enabled to send RSTs or Disabled to stop sending RSTs. TCP contains six |
| control bits, with one or more defined in each packet. RST is one of the control |
| bits. The RST bit is responsible for telling the receiving TCP stack to end a |
| connection immediately. |
| Note: Setting the RSTs may pose a security risk. |
|
|
Ack Limit | Enter a number to limit how many packets get received before an ACK gets forced. |
| If there is a large amount of data to acknowledge, an ACK gets forced. If the |
| sender TCP implementation waits for an ACK before sending more data even |
| though the window is open, setting the Ack Limit to 1 packet improves |
| performance by forcing immediate acknowledgements. |
Send Data | The Send Data selection governs when data may be sent into the network. The |
| Standard implementation waits for an ACK before sending a packet less than the |
| maximum length. Select Expedited to send data whenever the window allows it. |
