Undefined (Disabled) |
Incoming Target Rate Cap (Kbps) |
The maximum target rate for incoming transfers, in kilobits per second. No transfer
session can exceed this rate at any time. If the client requests an initial rate greater than the
target rate cap, the transfer proceeds at the target rate cap. The default setting of
unlimited applies no target rate cap.
|
positive integer |
unlimited |
Incoming Target Rate Default (Kbps) |
The default initial rate for incoming transfers, in kilobits per second. If allowed,
Incoming Target Rate Lock is set to false , clients can
modify this rate in real time. This setting is not relevant to transfers with a
fixed bandwidth policy.
|
positive integer |
10000 |
Incoming Target Rate Lock |
Lock the target rate of incoming transfers.
true - Locks the target rate of incoming transfers.
false - Allow users to adjust the transfer rate of an incoming transfer
up to the Incoming Target Rate Cap .
|
true or false |
false |
Incoming Minimum Rate Cap (Kbps) |
The highest minimum rate that an incoming transfer can request, in kilobits per second.
Client minimum rate requests that exceed the minimum rate cap are ignored. The default value of
unlimited applies no cap to the minimum rate.
|
positive integer or unlimited |
unlimited |
Incoming Minimum Rate Default (Kbps) |
The default initial minimum rate for incoming transfers, in kilobits per second. If
allowed, Incoming Minimum Rate Lock is set to false and clients
can modify the minimum rate in real time, up to the Incoming Minimum Rate Cap.
This setting is not relevant to transfers with a fixed bandwidth
policy.
|
positive integer |
0 |
Incoming Minimum Rate Lock |
Lock the minimum rate of incoming transfers.
true - Locks the minimum rate of incoming transfers.
false - Allow users to adjust the minimum transfer rate up to the
Incoming Minimum Rate Cap .
This setting is not relevant to transfers with a fixed bandwidth
policy.
|
true or false |
false |
Incoming Bandwidth Policy Allowed |
The bandwidth policies that incoming transfers can use. These policies transfers can use
high, fair, low, or fixed bandwidth policies to determine bandwidth allocation among transfers.
any - The server does not deny any transfer based on policy
setting.Note: Setting to any allow clients to request a fixed
bandwidth policy. If the client also requests a high minimum transfer rate and that is not capped by
the server, the transfer rate can exceed network or storage capacity. This can decrease transfer
performance and cause problems on the target storage. To avoid these problems, set the allowed
policy to fair .
high - Transfers that use high ,
fair , or low bandwidth policies are allowed. Transfers that
request fixed bandwidth policy are rejected.
fair - Transfers that use fair or low
bandwidth policies are allowed. Transfers that request fixed bandwidth policy are
rejected.
low - Only transfers that use a low bandwidth policy
are allowed. All others are rejected.

Incoming Bandwidth Policy Default |
The default bandwidth policy for incoming transfers. Clients can override the default
policy if they specify a policy allowed by the server. See Incoming Bandwidth Policy
Allowed and if Incoming Bandwidth Policy Lock is set to
false .
high - Adjust the transfer rate to fully use the available bandwidth up
to the maximum rate. When congestion occurs, the transfer rate is twice as fast as a fair-policy
transfer. The high policy requires maximum (target) and minimum transfer
rates.
fair - Adjust the transfer rate to fully use the available bandwidth up
to the maximum rate. When congestion occurs, bandwidth is shared fairly by transferring at an even
rate. The fair policy requires maximum (target) and minimum transfer rates.
low - Adjust the transfer rate to use the available bandwidth up to the
maximum rate. Similar to fair mode, but less aggressive when the bandwidth is shared with other
network traffic. When congestion occurs, the transfer rate is reduced to the minimum rate until
other traffic decreases.
fixed - Attempt to transfer at the specified target rate, regardless of
network or storage capacity. This can decrease transfer performance and cause problems on the target
storage. Use the fixed policy only for specific contexts, such as bandwidth testing, otherwise,
avoid the use of this policy. The fixed policy requires a maximum target rate.
aggressiveness - The aggressiveness of transfers that are authorized by
this access key in claiming available bandwidth. Value can be 0.00-1.00. For example, these values
correspond to the policy option where a policy of high approximates to aggressiveness of 0.75, fair
to 0.50 and low to 0.25. Aggressiveness can be used if you need to fine-tune the transfer
policy.

Incoming Bandwidth Policy Lock |
Lock the bandwidth policy of incoming transfer sessions.
true - Locks the bandwidth policy of incoming transfer sessions.
false - Allow users to adjust the bandwidth policy.

true or false |

Incoming Rate Control Module |
Set how the transmission rate should be managed relative to instantaneous
network bandwidth availability. This option can be changed only by advanced users. When the client does not specify a configuration, the server configuration is used.
When the client specifies a value other than delay and the client is the receiver,
then the client configuration overrides the server configuration.
Values:
delay - The baseline rate control module used by the transfers.
delay-odp - A queue-scaling controller for overdrive protection.
delay-adv - An advanced rate controller.
delay-laq - A loss-adjusted queuing (LAQ) rate controller.Note: The LAQ
module is an experimental rate control module that is designed to solve issues with target rate
overdrive, high concurrency when many FASP sessions run at the same time, and shallow buffers so
that the limited packet queuing capability of a router. When LAQ is set, then it uses the FD31 RTT
predictor unless a different RTT predictor is explicitly set.
To set a rate control module for outgoing traffic, set it from the command line. See aspera.conf - Transfer configuration.

Incoming Traffic RTT Predictor |
The type of predictor to use to compensate for feedback delay when
measuring RTT.
An experimental feature that might increase transfer rate stability and
throughput by predicting network congestion. When set to unset , the client
specified predictor is used and if the client does not specify a predictor, then none is used. For
more information, see Increasing transfer performance by using an RTT Predictor.

Incoming Rate Control Target Queue |
The method for calculating the target queue. For more
information, see Increasing transfer performance by using an RTT Predictor.
unset - The transfer queuing is not specified, therefore, the static
transfer queuing is used.
static - Specified transfer queuing is good for most internet
connections.
dynamic - Specified transfer queuing is good for satellite and other
radio connections.
