What is FASP
It is an innovative file transfer technology patented by Aspera.
It is an innovative software that eliminates the fundamental shortcomings of conventional TCP based file transfer technologies such as HTTP and TCP.
It provides a guaranteed delivery time regardless of file size, transfer distance or network conditions.
Enables large data transfers over any network at maximum speed, regardless of network conditions or distance.
Very lightweight, does not require specialised or powerful hardware to maintain high speeds.
Extraordinary bandwidth control Provides precise rate control for guaranteed transfer times.
Provides fast automatic discovery of the bandwidth capacity between the source and destination.
Includes complete, built-in security using open standard cryptography for user authentication, data encryption and data integrity verification.
Uses standard IP networking and is implemented in software as an application protocol.
Robust and Flexible open architecture
Provides end-to-end transfer progress reporting and detailed performance statistics for monitoring and billing
In this digital world, fast and reliable movement of digital data, including massive sizes over global distances, is becoming vital business success across virtually every industry.
TCP has inherent bottlenecks in performance, especially for networks with high round-trip time and packet loss.
TCP' s Adiitive Increase Multiplicative Decrease congestion avoidance algorithm, in ramping up the, until loss occurs, AIMD inherently overdrives the available bandwidth
Need for FASP
Transporting bulk data with maximum speed calls for an end-to-end approach that fully utilizes available bandwidth along the entire transfer path from data source to data destination.
Aspera fasp is an innovative bulk data transport technology built on these core principles that is intended to provide an optimal alternative to traditional TCP-based transport technologies for transferring files over public and private IP networks.
Shortcomings of TCP transfer
TCP file transfers are slow and bandwidth utilization of single file transfers is poor.
The bandwidth utilization problem compounds on wide area links where increased network latency combines with packet loss.
TCP file transfers over difficult networks (with high packet loss or variable latency) are extremely slow and unreliable.
TCP file transfer rates and times are unpredictable.
The FASP solution
fasp is a new large data transport protocol that achieves reliability in the application layer in a novel approach that eliminates TCP's inefficient loss and error handling, and the resulting erratic transfer rate swings.
fasp implements its own, theoretically proven optimal mechanism that identifies and retransmits precisely the real packet loss on the channel.
fasp has ideal bandwidth efficiency, and does not flood the network with redundant data, or deny access to standard TCP applications.
