关于Aspera

1、Aspera took a different approach: solving the problem by eliminating the underlying bottleneck altogether.
This allowed us to create a breakthrough transport technology that can fully utilize the available network bandwidth,
transfer data at maximum speed, and scale up as needed with no theoretical limit.
This philosophy of innovation is fused into Aspera’s DNA,
and built into the core technology and software products that fuel the company’s consistent and rapid growth.
******************************************
Aspera采用了不同的方式:通过消除潜在的瓶颈来解决问题。
这种思路,使得我们创建了一种突破性的传输技术,该技术可以完全利用可用的网络带宽,以最大速率传输数据,可以按需要调整而没有理论上的限制;
这种革命性的理念已融入到Aspera的DNA中,
并且贯穿到核心技术和软件产品中,驱动了公司的持续发展和快速增长。

手机用户可以利用fasp-AIR技术在iOS和Android设备之间高速传输数据。
无论是私有还是公有存储及云计算方面,云和NAS平台都可以从Aspera传输服务器和web应用的极具扩展性上获取好处。
一套综合性的web应用和组件能够在各种业务应用场景中进行基于web的高速数据传输。
****************************************************
4、Aspera’s high-performance fasp?? transport technology can easily be embedded thanks to a comprehensive software development kit featuring SOAP web services and Javascript APIs,
as well as cross-platform libraries for Mac, Windows and Linux (Java, C++, C#, .NET).
A subscription to Aspera Developer Network provides users with comprehensive and up to date libraries,
documentation and user guides, and detailed code samples.

Aspera的高性能fasp传输技术可以很容易的嵌入到许多软件开发工具包,比如具有SOAP特性的webservice或者Javascript API,
也可以跨操作系统使用的,如:Mac, Windows 和 Linux (Java, C++, C#, .NET).
通过订阅Aspera开发者网络,可以给用户提供全面、最新的库包、文档、用户指南和详细的代码样例。
****************************************************
5、 As a result, fasp transfers maximize the utilization of available bandwidth to deliver unmatched transfer speeds
and to provide a guaranteed delivery time regardless of file size, transfer distance or network conditions.

因此,fasp传输最大化利用可用带宽,获得了无与伦比的传输速度,并且能够保证传输时间不受文件大小、传输距离和网络条件的限制。
************************************************
6、总之,一句话Aspera传输技术可以在任何时间、任何情况下最大化利用可用带宽。(跟时间和地点无关)



7、Aspera的fasp是应用层的协议(避免对底层网络的改造),如何做到高速传输?
>>>7.1以网络队列的延迟作为主要的拥堵控制信号,将丢包率作为辅助的信号,这样能够更精准的评估网络拥堵;
>>>7.2嵌入式的快速响应机制(the embedded quick response mechanism)
>>>7.3高级反馈控制机制(the advanced feedback control mechanism)
>>>7.4带宽的完全利用(the full utilization of bandwidth)
如何做到?
A、完全解耦可靠性控制和拥塞控制(流控制);
B、不要求字节流分发;
C、能够精确的在通道上重新转发真正丢失的数据包



8、注意:Aspera fasp是适合用于WAN(广域网)下的大数据高速传输技术。==>
因为,如果是局域网或者专网时,通过MQ就可以达到90%以上的带宽利用率。


9、Aspera fasp使用的解决方案是:在传输层采用UDP,也是在应用层进行可靠性保证,不要求字节流分发,(在应用层)完全解耦可靠性和拥塞控制。
