Description
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.
