Storage Network Solution
Concept
Aspera proprietary FASP technology makes fast and reliable bulk data transfer possible.
 |
 |
 |
【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
