default buffer-size

default

Restores default values assigned to its following options.

Usage Guidelines

Use this command to configure the TCP Proxy buffer size for downlink and uplink data in Kilobytes

Example

The following command configures a TCP Proxy buffer size for downlink data as 256KB and uplink data as 256KB:

buffer-size downlink 256KB uplink 256KB

cwnd-gain

This command configures the TCP congestion window gain by continuously evaluating the actual congestion window size.

Mode

Exec > ACS Configuration > ACS TCP Acceleration Profile Configuration

active-charging service service_name > tcp-acceleration-profile profile_name

Entering the above command sequence results in the following prompt: 

[local]host_name(config-acs-tcp-accl-profile)#

Syntax

cwnd-size { dynamic { off | on } [ factor factor_value ] | factor factor_value [ dynamic { off | on } ] }  
default cwnd-gain

default

Restores default values assigned to its following options.

dynamic

Automatically scales-up the congestion window gain to ensure that it is sized correctly to allow for RTT variation during the flow.

factor factor_value

Configures the TCP congestion window gain factor. The factor_value is an integer ranging from 1 to 16378.

Usage Guidelines

Use this command to configure the TCP congestion window gain by continuously evaluating the actual congestion window size. This command is used by the TCP optimization engine to continuously calculate the actual congestion window size. Scaling the window size allows the TCP optimization engine to manage the in-flight of data in the engine.

Example

The following command configures TCP congestion window size dynamically along with a gain factor value 10:

cwnd-size dynamic on factor 10

end

Exits the current configuration mode and returns to the Exec mode.
