TCP Profile > Time Wait Recycle

SOL7559 states, for the TCP Profile Time Wait Recycle setting;

 

"The system will recycle or reuse the connection when a SYN packet is received in a TIME/WAIT state. This option allows the system to better optimize system resources by reusing a connection in a TIME/WAIT state when a SYN packet is received, instead of creating a new connection."

 

Would anyone know, a SYN packet from where, the same client or any client? And one matching the same connection parameters (i.e. source port)?

    Hi Steve,

     

     

    Sorry I can't answer this already. I suggest opening a support case to find out.

     

     

    Thanks, Aaron

    Hi Steven,

     

    I faced the same uncertainty reading the SOL, and finally found a way better explanation.

     

    Within the GUI itself, the Help tab mentions:

     

    Time Wait Recycle: Specifies, when checked (enabled), that connections in a TIME-WAIT state are reused when the system receives a SYN packet, indicating a request for a new connection. When this setting is not enabled, connections in a TIME-WAIT state remain unused for a specified length of time (typically twice the maximum segment lifetime), to ensure that the original transmission is complete. Using this setting enabled, the system can recycle a wait-state connection immediately upon receipt of a new connection request instead of having to wait until the connection times out of the wait state. By default, this setting is enabled.

     

    Hope this helps, Mathieu.
