A new approach to fast data transfer

IBM Aspera® takes a different approach to tackling the challenges of big data movement over global WANs. Rather than optimize or accelerate data transfer, Aspera completely eliminates underlying bottlenecks using a breakthrough transport technology. It fully utilizes available network bandwidth to maximize speed and quickly scale up with no theoretical limit.   

Technology you can rely on

Maximum speed

To achieve speeds up to hundreds of times faster than FTP and HTTP, the IBM Aspera FASP® protocol uses a unique and patented approach that enables maximum speed without network saturation.

Reliable and predictable

Aspera provides a high degree of reliability with automatic resume and restart from the point of interruption. It enables users to predict transfer time, regardless of distance or network conditions.

Comprehensive built-in security

To ensure exceptional security for business-critical digital assets, Aspera uses open standards cryptography for user authentication, data encryption and data-integrity verification.

At the heart of the Aspera solutions is the patented FASP transport software technology. The groundbreaking protocol overcomes the traditional limitations of TCP-based transfers to maximize the usage of available bandwidth, without impacting other network traffic. The result is unmatched transfer speeds, end-to-end security, reliability and exceptional bandwidth control.

Aspera features

Extraordinary bandwidth control

The intelligent adaptive transmission-rate control mechanism in the FASP protocol enables fast, automatic discovery of available bandwidth to fully utilize capacity while being fair to other traffic.

Flexible and open architecture

Aspera supports interoperable file and directory transfers between all major operating systems and cloud platforms, and provides a complete, modern software API.

Software-only design

Aspera is a software-based technology that can run on commodity hardware and over standard, unmodified IP networks, making for easier, more scalable deployments and lower total cost of ownership.


The Aspera streaming technology is a revolutionary alternative for error-free transport of large data streams and any-bit-rate video over any distance on unmanaged internet with near-zero latency. Built on Aspera FASP, this technology provides fully reliable in-order byte stream delivery of live feeds and growing files over commodity IP networks, using the new streaming architecture.

Built into Aspera cloud offerings is the unique direct-to-cloud technology. It integrates FASP high-speed transport with the underlying multi-part HTTP interfaces of the cloud object storage layer, enabling the fastest file uploads and downloads on all major cloud platforms. Aspera cloud technology also includes important transfer management features such as pause, automatic resume, reporting, and encryption over the wire and, optionally, at rest.

The Aspera transfer platform includes auto-scale capabilities for dynamic, real-time scale out of transfer capacity. They include automatic start and stop of transfer server instances, available idle instances, automatic balancing of client requests and configurable service levels to manage transfer load per instance. The new multisession transfer technology expands the auto-scaling capability, enabling clients to achieve multi-gigabit transfer speeds.
