Concept
Aspera proprietary FASP technology makes fast and reliable bulk data transfer possible.

FTP FASP

【FTP】
1.Poor bandwidth utilization.
2.Thruput is extremely slow due to
 Packet loss and Latency.
3.File transfer rate is unpredictable.
 Therefore,
 Long distance file transfer can be
 extremely slow and unreliable.

 

【FASP】
1.Efficient bandwidth utilization.
2.Thruput is extremely high
 regardless of network conditions.
3.File transfer rate is predictable.
 Therefore,
 Long distance file transfer is
 faster and reliable.


FASP Technology

■FASP
 ・Patent-pending protocol for fast
 and reliable bulk data transfer


■Speed
 ・Maximum speed and guaranteed
 transfer time independent of
 network distance,packet loss on
 the media, and variable congestion,
 including

■Bandwidth Efficiency
 ・Fully utilizes very high-speed
 links with very low protocol
 overhead (0.1% or less)

■Bandwidth control
 ・Pre-set and on-the-fly throttling
 and prioritization capability per
 transfer
 ・Set max/min rate, aggressiveness
 policy (“fixed”, “adaptive”,
 “stealth”),
 and finish time

■Bandwidth sharing
 ・Automatically adapts to use
 available
 bandwidth while protecting
 other raffic
 ・Policies allow for one-for-one
 airness to TCP
