Global Bandwidth Settings

Aspera FASP transport has no theoretical throughput limit. In addition to network capacity, transfer rates can be limited by user-configured rate settings and the resources of the local and remote machines. You can configure bandwidth usage limits and the number of concurrent FASP transfers that are allowed by HST Server.

1. Launch the application with administrator privileges and click Tools > Global Preferences.
   
2. Click Transfers.
   
3. To limit total bandwidth usage by FASP uploads and downloads, edit System-Wide Settings.
   System-wide settings set the aggregated bandwidth cap for all FASP transfers on this computer.

   To override the default bandwidth limits, under System-Wide Settings select the boxes next to Limit Download Bandwidth and Limit Upload Bandwidth and enter new values in the fields. The global settings for download and upload bandwidth limits cannot be reset by non-admin users. However, users can view the global limit from the Preferences > Transfers dialog.

   Note: When global bandwidth limits are set, the application creates virtual links (Vlink) and applies them to the default transfer settings. For more information about Vlinks, see Controlling Bandwidth Usage with Virtual Links (GUI).

   For more advanced bandwidth settings, see Bandwidth Configuration.

4. To set default target rates for all users, edit Default Target Rate.
   Non-admin users can adjust their personal default target rates above or below the global default value.
5. To limit the number of active transfers, edit Maximum Active Transfers.
   Non-admin users can adjust their personal maximum active transfers above or below the global default value.
6. Click OK to activate your changes.
