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.


FASP transfers can achieve speed hundreds of times
faster than FTP/HTTP.


It provides a guaranteed delivery time regardless of
file size, transfer distance or network conditions.

●

Transport characteristics
Maximum speed

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.
Transport characteristics
●

Complete Security

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.
Need for FASP

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
The loss based congestion control in TCP, AIMD has
a deadly impact on throughput.
●

Every packet loss leads to to retransmission, and stalls
the delivery of data to the receiving application until
retransmission occurs.
●

This coupling of reliability (retransmission) to
congestion control in TCP creates a severe artificial
throughput penalty for file transport, as evident by the
poor performancetraditional file transfer protocols built
on TCP such as FTP, HTTP over wide area networks
●
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

Fig : TCP performance over increasing network latency and packet loss conditions
normally present on long-distance WANs
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

Fig : Fasp versus TCP on a 1Gbps WAN link over increasing network latency and
packet loss.
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.
●
The FASP solution
●

Automative Adaptive Rate Control :

Whereas TCP self-limits its transfer rate even on an
uncongested link, fasp™ detects the unused bandwidth
and ramps up to fill it.
● When congestion builds up, fasp reduces its rate to
accommodate TCP traffic and equally shares the link
with multiple TCP flows.
● This makes fasp Loss tolerant, Perfectly efficient, and
Stable.
●
The FASP solution
●

Complete security :

The fasp protocol provides complete built-in security
without compromising transfer speed.
● The security model, based solely on open standards
cryptography, consists of SSH authentication, on-thefly data encryption using strong cryptography (AES128) for privacy of the transferred data, and an
integrity verification per data block.
● It safeguard against man-in-the-middle and
anonymous UDP attacks.
●
The FASP solution
●

Complete security :

The transfer preserves the native file system access
control attributes between all supported operating
systems, and is highly efficient.
● With encryption enabled, fasp achieves WAN file
transfers of 100-200 Mbps on a single processor
machine or laptop; and 200-500 Mbps+ on dualprocessor or duo-core workstations.

Conclusion
The market need for a flexible, next generation file
transfer technology is pervasive and
●

exploding as file sizes increase, network capacities
grow, and users increasingly exchange
data and media.

As an all-software platform deployable on any
standard computing device, fasp is capable of filling
the next-generation need, providing optimal data
transfer in an application, over any Internet network,
from consumer broadband to gigabit core.

Fast and secure protocol (fasp)

  • 1. 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.  FASP transfers can achieve speed hundreds of times faster than FTP/HTTP.  It provides a guaranteed delivery time regardless of file size, transfer distance or network conditions. 
  • 2. ● Transport characteristics Maximum speed 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.
  • 3. Transport characteristics ● Complete Security 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.
  • 4. Need for FASP 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. ●
  • 5. Need for FASP The loss based congestion control in TCP, AIMD has a deadly impact on throughput. ● Every packet loss leads to to retransmission, and stalls the delivery of data to the receiving application until retransmission occurs. ● This coupling of reliability (retransmission) to congestion control in TCP creates a severe artificial throughput penalty for file transport, as evident by the poor performancetraditional file transfer protocols built on TCP such as FTP, HTTP over wide area networks ●
  • 6. 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. ●

  • 8. 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.

  • 10. 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. ●
  • 11. The FASP solution ● Automative Adaptive Rate Control : Whereas TCP self-limits its transfer rate even on an uncongested link, fasp™ detects the unused bandwidth and ramps up to fill it. ● When congestion builds up, fasp reduces its rate to accommodate TCP traffic and equally shares the link with multiple TCP flows. ● This makes fasp Loss tolerant, Perfectly efficient, and Stable. ●
  • 12. The FASP solution ● Complete security : The fasp protocol provides complete built-in security without compromising transfer speed. ● The security model, based solely on open standards cryptography, consists of SSH authentication, on-thefly data encryption using strong cryptography (AES128) for privacy of the transferred data, and an integrity verification per data block. ● It safeguard against man-in-the-middle and anonymous UDP attacks. ●
  • 13. The FASP solution ● Complete security : The transfer preserves the native file system access control attributes between all supported operating systems, and is highly efficient. ● With encryption enabled, fasp achieves WAN file transfers of 100-200 Mbps on a single processor machine or laptop; and 200-500 Mbps+ on dualprocessor or duo-core workstations. ●
