Chapter 3 CLI Commands

(config) tfo tcp optimized-send-buffer

To configure a WAE for Traffic Flow Optimization (TFO) with an optimized-side send buffer, use the

tfo tcp optimized-send-buffer global configuration command. To disable this function, use the no form

of this command.

tfo tcp optimized-send-buffer buffer-size

no tfo tcp optimized-send-buffer buffer-size

Syntax Description

Defaults 32 KB

Command Modes global configuration

Device Modes application-accelerator

Usage Guidelines The buffer should be equal to or greater than twice the Bandwidth Delay Product (BDP). The BDP is

equivalent to the bandwidth (in bits per second) * latency (in seconds). For example, for a 45-Mbps link

with a 150-ms (0.15 sec) round-trip delay, the BDP is 45 Mbps * 0.15 sec = 6.75 Mb, or 0.844 MB

(844 KB). In this case, you could set the buffer size to 2000 KB.

Examples The following example shows how to configure a WAE for Traffic Flow Optimization with a 32 KB

optimized-side send buffer using the tfo tcp optimized-send-buffer command:

WAE(config)# tfo tcp optimized-send-buffer 32
