In this digital era, persistent and reliable movement of digital data, including massive sizes over universal distances, is becoming vital to business success across virtually every industry. The Transmission Control Protocol that has conventionally been the engine of this data movement, however, has inherent impasses in performance.
What exactly is FASP?
Fast and Secure Protocol (FASP) is an innovative file transfer tech by Aspera. It is a software which evacuates the fundamental shortcomings of traditional TCP based data transfer technologies such as HTTP or TCP itself.
FASP is flexible and open architecture with maximum speed and reliability. Unlike TCP, FASP transfer is robust and can achieve speed hundred times faster than HTTP/FTP. With built-in security and extraordinary bandwidth control, it provides an assured and secured delivery time regardless of transfer distance, file size or network conditions.
Why do we need FASP and how it works?
Sharing and Transferring electronically stored information (ESI) is becoming a natural part of most company’s daily operations. However, present technologies cannot handle the increasing growth of data, thereby increasing costs and inhibiting productivity.
Transmission Control Protocol, an underlying protocol behind most of today’s data transfer applications, creates packet loss by overdriving the use of available bandwidth then instantaneously brings down the transmission rate & slowly accelerating it back up, just to overdrive it again. This, however results in an immensely decreased overall transmission rate and underutilization of available bandwidth. This is the reason why transfers are slow.
Fast and Secure Protocol fills the gap left by TCP in supplying reliable transport for applications which does not require byte-stream delivery and thoroughly segregates reliability and rate control. It uses standard User Datagram Protocol (UDP) in the transport layer and attains decoupled congestion and reliability control in the application layer through a technical optimal approach that retransmits the real packet loss accurately on the channel. Due to the decoupling of the reliability and rate control, new packets need not slow down for the retransferring of lost packets as in TCP-based byte streaming applications. Data which is lost in transmission is retransmitted at a rate that meets the available bandwidth inside the end-to-end path, with zero duplicate retransmissions for zero receiving cost.
The market needs a flexible, next-generation file transfer technology which should be universal and efficient as network capacities grow and file sizes increase, and where users can easily exchange data and media. As an all software platform deployable on any standard computing device, Fast and Secure Protocol (FASP) is capable of filling the void of next-generation needs, providing optimal data transfer in an application, from consumer broadband to gigabit core, over any Internet network.
