UDP Data Transfer

UDP-based Data Transfer Protocol (UDT), is a high performance data transfer protocol designed for transferring large volumetric datasets over high speed wide area networks. Such settings are typically disadvantageous for the more common TCP protocol.

Initial versions were developed and tested on very high speed networks (1Gbit/s, 10Gbit/s, etc.); however, recent versions of the protocol have been updated to support the commodity Internet as well. For example, the protocol now supports rendezvous connection setup, which is a desirable feature for traversing NAT firewalls using UDP.
