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

Abstract

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
