UDT: An Application Level Transport Protocol for Grid Computing
Overview As network bandwidth and delays increase, TCP becomes inefficient. These problems are due to slow loss-recovery, a RTT bias inherent in its AIMD congestion-control algorithm, and the bursting data flow caused by its window control. Data-intensive applications over high bandwidth delay product (BDP) networks, such as computational grids, need new transport protocols to support them. To meet this requirement an application-level protocol is built above UDP, called UDP-based Data Transfer protocol, or UDT. UDT has a congestion control mechanism that maintains efficiency, fairness and stability, and its application-level nature enables it to be deployed at the lowest cost, without any changes in the network infrastructure or operating systems.
