Dynamically Optimized Transport System

Accelerate your application

Deliver your data faster

DOTS (Dynamically Optimized Transport System) is the nuu:bit platform’s advanced and intelligent TCP congestion control algorithm designed specifically to improve last-mile Internet delivery. Our patent pending invention outperforms existing CDN solutions by up to 3X.

DOTS does not require a software agent on the receiving end, as it is built with the focus to accelerate HTTP content delivery asymmetrically; this elegant yet powerful feature contrasts an SDK’s requirement for special software to be compiled in the App that runs on the edge device. Leveraging DOTS, nuu:bit’s leading core technology with three key pending patents, we are sending data even faster and cheaper with ever increased efficiency. We gain 20% to 300% on web performance depending on the network conditions over standard TCP protocol performance.

DOTS does not modify the payload (that is, it doesn’t perform any content optimization on transmitted data), and is very safe for complex web applications that might be sensitive to content alterations.


DOTS is an ideal choice for content publishers and developers of both websites and mobile Apps because of its content-agnostic mechanism. More importantly, DOTS learns, adapts, and modifies its configuration and operation on the fly to accurately and securely maximize throughput to the mobile and wired edge device.

How it works

DOTS is designed to be adaptable for the changing conditions presented in many networks while accelerating transport of web content over the wired networks, which typically have lower rates of change than cellular networks. DOTS overcomes problems created by the small receiving buffer size and the asymmetric link pathways of cellular networks, along with several other unique characteristics of the cellular network.

DOTS’s transport protocol utilizes the latest innovation in modern network queuing theory and communications protocol design and is designed to be compatible with the operation of conventional TCP implementations. Because of this, DOTS resides on the nuu:bit CDN edge for last mile delivery.

By applying any previous experience with the particular end user IP address, prior network traffic conditions, and network type, DOTS will configure itself appropriately for each transmission on a session-by-session basis. So, if network conditions have changed, DOTS will respond and act accordingly. DOTS will accelerate web content to the maximum rate consistent with present network conditions and end user device capabilities. With the next access by the end user, DOTS will apply the configuration it has learned is best for that end user device and network as a starting point so that the transport acceleration DOTS provides has already benefitted from any prior experience. While transporting content, DOTS continually adjusts itself to changing conditions on the fly, maximizing its performance while sensing any limiting conditions that require real time modification of DOTS behavior.
