Disable Delayed Acknowledgements.
This socket option can be used to reduce or disable delayed acknowledgments (ACKs). When TCP_QUICKACK
is enabled, ACKs are sent immediately, rather than delayed if needed in accordance to normal TCP operation. This option is not permanent, it only enables a switch to or from TCP_QUICKACK
mode. Subsequent operations of the TCP protocol will once again disable/enable TCP_QUICKACK
mode depending on internal protocol processing and factors such as delayed ACK timeouts occurring and data transfer, therefore this option needs to be set with setOption
after each operation of TCP on a given socket.
The value of this socket option is a Boolean
that represents whether the option is enabled or disabled. The socket option is specific to stream-oriented sockets using the TCP/IP protocol. The exact semantics of this socket option are socket type and system dependent.
