Name Description Type Notes

Controls the our congestion window to send, normally it's 1
mss, If this option is turned on, we use 10 msses.
Default value when not specified in API or module is
interpreted by ALB Controller as false.

Controls whether the windows are static or supports
autogrowth.
Maximum that it can grow to is limited to 4MB.
Default value when not specified in API or module is
interpreted by ALB Controller as true.
boolean Default: "True"

automatic Automatic

Dynamically pick the relevant parameters for connections.
Default value when not specified in API or module is
interpreted by ALB Controller as true.

Enum options - CC_ALGO_NEW_RENO, CC_ALGO_CUBIC,
CC_ALGO_HTCP.
Default value when not specified in API or module is
interpreted by ALB Controller as CC_ALGO_NEW_RENO.

Congestion window scaling factor after recovery.
Allowed values are 0-8.
Default value when not specified in API or module is
interpreted by ALB Controller as 2.
integer Minimum: 0
Maximum: 8
Default: "2"

idle_connection_timeout Idle connection timeout

The duration for keepalive probes or session idle timeout.
Max value is 3600 seconds, min is 5.
Set to 0 to allow infinite idle time.
Allowed values are 5-14400.
Special values are 0 - 'infinite'.
Unit is SEC.
Default value when not specified in API or module is
interpreted by ALB Controller as 600.
integer Minimum: 0
Maximum: 14400
Default: "600"

Controls the behavior of idle connections.
Enum options - KEEP_ALIVE, CLOSE_IDLE.
Default value when not specified in API or module is
interpreted by ALB Controller as KEEP_ALIVE.
ALBIdleConnectionType Default: "KEEP_ALIVE"

ignore_time_wait Ignore time wait

A new SYN is accepted from the same 4-tuple even if there
is already a connection in TIME_WAIT state.
This is equivalent of setting Time Wait Delay to 0.
Default value when not specified in API or module is
interpreted by ALB Controller as false.
boolean Default: "False"

ip_dscp Ip dscp

Controls the value of the Differentiated Services Code
Point field inserted in the IP header.
This has two options Set to a specific value, or Pass
Through, which uses the incoming DSCP value.
Allowed values are 0-63.

Default value when not specified in API or module is
interpreted by ALB Controller as 0.
integer Minimum: 0
Maximum: 63
Default: "0"

keepalive_in_halfclose_state Keepalive in halfclose state

Controls whether to keep the connection alive with
keepalive messages in the TCP half close state.
The interval for sending keepalive messages is 30s.
If a timeout is already configured in the network profile,
this will not override it.
Default value when not specified in API or module is
interpreted by ALB Controller as true.
boolean Default: "True"

connection.

interpreted by ALB Controller as false.
boolean Default: "False"

integer Minimum: 2
Maximum: 65536
Default: "64"

reorder_threshold Reorder threshold

Controls the number of duplicate acks required to trigger
retransmission.
Setting a higher value reduces retransmission caused by
packet reordering.
A larger value is recommended in public cloud environments
where packet reordering is quite common.
The default value is 8 in public cloud platforms (AWS,
Azure, GCP), and 3 in other environments.
Allowed values are 1-100.
integer Minimum: 1
Maximum: 100

slow_start_scaling_factor Slow start scaling factor

Congestion window scaling factor during slow start.
Allowed values are 0-8.
Default value when not specified in API or module is
interpreted by ALB Controller as 1.
integer Minimum: 0
Maximum: 8
Default: "1"

time_wait_delay Time wait delay

The time (in millisec) to wait before closing a connection
in the TIME_WAIT state.
Allowed values are 500-2000.
Special values are 0 - 'immediate'.
Unit is MILLISECONDS.
Default value when not specified in API or module is
interpreted by ALB Controller as 2000.
integer Minimum: 0
Maximum: 2000
Default: "2000"

use_interface_mtu Use interface mtu

Use the interface MTU to calculate the TCP max segment
size.
Default value when not specified in API or module is
interpreted by ALB Controller as true.
boolean Default: "True"
