UCONF: Transfer acceleration

To enable acceleration set the uconf values as recommended in this section.

About transfer acceleration

UNIX/Windows only

The Transfer CFT acceleration feature offers significantly faster transfer rates for large-file transfers, traveling long-distances over high bandwidth networks.

Transfer CFT achieves this transfer acceleration using two methods:

  • UDT: a UDP-based protocol (User Datagram Protocol)
  • pTCP: parallel TCP, which uses multiple parallel connections

UDT description

UDT is a transport protocol that Transfer CFT can use to manage applications over high-speed networks. UDT uses UDP, a lower layer message, to transfer bulk data.

Configuring accelerated communication

To enable accelerated communication in the GUI select the Unified configuration option, or in CFTUTIL use the unified configuration command UCONFSET.

Parameter Description
acceleration.enable Activate/deactivate the acceleration option.
acceleration.udt UDT default peer definition.
acceleration.ptcp pTCP default peer definition.

pTCP protocol versions

Transfer CFT 3.0.1 SP2 and higher, and Transfer CFT 2.7.1 SP6, support a more recent version of the pTCP protocol than previously supported by Transfer CFT. This newer version of pTCP offers the following advantages:

  • Multi-node architecture support
  • Exchange capability with Axway SecureTransport

Note that the new pTCP support is not compatible with the previously used version of pTCP. This means that Transfer CFT 3.0.1 SP2 and higher, and Transfer CFT 2.7.1 SP6, cannot exchange files with earlier versions of Transfer CFT using the pTCP protocol.

For more information on supported platforms and transfer acceleration, refer to Platform-specific functionality.
