UDT（UDP-based Data Transfer Protocol，简称UDT）是一种互联网数据传输协议。UDT建于UDP之上，并引入新的拥塞控制和数据可靠性控制机制。UDT是面向连接的双向的应用层协议。它同时支持可靠的数据流传输和部分可靠的数据报传输。 (UDT is a reliable UDP based application level data transport protocol for distributed data intensive applications over wide area high-speed networks. UDT uses UDP to transfer bulk data with its own reliability control and congestion control mechanisms. The new protocol can transfer data at a much higher speed than TCP does. UDT is also a highly configurable framework that can accommodate various congestion control algorithms)
