TCP Delayed Ack
To cut back on network traffic, a host will not send an acknowledgment right away, possibly allowing more than one TCP data package to be acknowledged in one reply packet or an acknowledgment of the packet to be sent along with data to be sent to the remote host. Sending an acknowledgment may be delayed based upon the following rules:
- An ack cannot be delayed more than CFG_MAX_DELAY_ACK msecs.
- In a stream of full sized (maximum segment size) packets, every other packet must be acknowledged.
- Delay ack must be enabled for the socket. This option can be enabled or disabled by function setsockopt. The default value is enabled.
