 Overview

 

UDT is an application level data transport protocol for the emerging distributed data intensive applications over wide area high-speed networks. UDT uses UDP to transfer bulk data and it has its own reliability control and congestion control mechanism. This new protocol is not only for private or QoS-enabled links, but also for shared networks. Furthermore, UDT is also a composable framework that can accommodate various congestion control algorithms. (Presentation: PPT 311KB)

 

UDT is designed and implemented by the National Center for Data Mining at the University of Illinois at Chicago. Currently the UDT project has released a productivity version (UDT 3.3) and a prototype of the future version (UDTv4 Beta).

 

The UDT Project was supported in part by NSF, DOE, and the US Army Pantheon Project.

UDT helped to reach 711Mb/s (peak 844Mb/s) disk-disk data transfer between US and Russia. Scientists from the National Center for Data Mining (NCDM) at the University of Illinois at Chicago and the Geophysical Center at the Space Research Institute, Russian Academy of Sciences, Moscow, demonstrated a new method for distributing extremely large volumes of scientific information across the world. They successfully moved 1.4 TeraBytes (TB) of data in about 4.5 hours over a 1 Gbps lightpath between Chicago and Moscow as part of the Teraflow Network initiative. This event, which represents the highest performance information transfer ever recorded between these two countries, was made possible by a unique international organizational partnership.
