Reliable and Efficient Data Transfer Protocol Based on UDP in Cluster System

In cluster system, a fast communication mechanism is absolutely necessarily. This paper deeply studies existing problems and limitation of primary data transfer protocols at present, proposes a reliable and efficient data transfer protocol based on UDP, also provides an analytical model to predict REUDP´s performance. REUDP make efforts to enhance the ability of cluster system communication under assured reliability. Theoretic analysis shows that REUDP can guarantee network reliability and high-speed bulk data transfer. Experiment results show that REUDP performs extremely efficiently over high speed dedicated networks and our model is able to provide good estimates of its performance
