Aspera's fasp™ transfer technology is an innovative (patent-pending) software that eliminates the fundamental bottlenecks of conventional file transfer technologies, and dramatically speeds transfers over public and private IP networks.

Our current version of the protocol, fasp™ 2, has several major improvements over fasp™ 1:

• Bandwidth Discovery - fasp™ 2 automatically discovers the path MTU (pMTU) size, thus avoiding packet fragmentation. This improves performance, and allows transfers to work in situations where fragmented packets are forbidden.
• Optimization for small files - fasp™ 2 introduces a file streamlining technique which eliminates the performance bottleneck when transferring multiple small files. This is a huge improvement over fasp™ 1.
• Improved Adaptive Transfer Rate - The improved adaptive rate control of fasp™ 2 enables users to utilize all available bandwidth along the transfer path, while sharing the network capacity fairly with other traffic.
• Parallel Transfer - fasp™ 2 introduces parallel transfer for server clusters or multi-core machines, enabling full leverage of computing power.
• Aggregate Bandwidth Management (Beta) - fasp™ 2 includes the aggregate bandwidth management to cap the total transfer rate of all Aspera transfers below a pre-configured bandwidth. This provides for flexible and on-demand configuration of sharing policy within the bandwidth cap.
• Symbolic Link Support (Beta) - fasp™ 2 is capable of handling symbolic links.
