| Enterprise Server Configuration and Transfer Reference / ascp4: Transferring from the Command Line with A4 | |
Aspera A4 is an optimized transfer engine based on FASP technology. A4 is designed for sending extremely large sets of individual files efficiently, and it supports UDP multicast. The executable, ascp4, is similar to ascp and shares many of the same options and capabilities. For more information on using ascp4 for UDP multicast, see the IBM Aspera Faspstream User Guide.
As installed, ascp is used for transfers intiated from the GUI and ascp4 transfers can only be initiated from the command line. For information on how to make GUI-initiated transfers use ascp4, see Using A4 from the GUI.
