About transport streamlining
The SteelHead family of appliances use a method called transport streamlining to reduce delays and improve the performance of TCP traffic between devices. This method combines standard and specialized techniques to:
use efficient ways to resend lost data like TCP selective acknowledgments.
adjust TCP window sizes for better data flow and reduced delay.
boost data transfer speeds over different types of WAN connections.
