Aspera is commercial software from IBM that handles large file transfers using an FTP-like client for Mac, Windows, and Linux that uses FASP networking when available and rolls back to HTTP when FASP isn't possible.

In contrast to TCP networking used by FTP or SFTP, FASP throughput is independent of network latency and robust to extreme packet loss that can be found on intercontinental WANs and on satellite, Wi-Fi or cellular connections. The result is transfer times that are hundreds of times faster than standard FTP and highly predictable, regardless of network conditions.

To achieve this performance, FASP does away with TCP's coupling of rate control and reliability, with a unique and patented approach that enables maximum transfer speeds, without compromising congestion avoidance, and achieves ideal efficiency and full bandwidth utilization.


This module is co-maintained by Aric Ruble (avguy) of Portland Community Media in Portland, OR as part of the CMDrupal project. It is designed to be used with other modules included in the Community Media Start Kit (Moderate). Consider joining the growing community who have made a commitment to contribute.

The modules included in the Aspera project include a core Aspera module that enables the Aspera client within specific Drupal form and module that manages the integration with the Community Media Show module.
