Research and Implementation of Data Transfer in Data Grid
数据网格环境中数据传输服务的研究与实现

In order to fast access data,Data Grid need to have a high-performance data transfer service to support data replica.A high-performance data transfer service should base on standard-protocol,and be convenient, robust,secure,etc.By partially modifying GridFTP,implement an independent of Globus,hight-performance,reliable data transfer service in Data Grid,which support a lot of functions such as security mechanism,parallel transfer,third party transfer.The paper anatomizes the GridFTP of Globus,finally introduces an instance of data transfer services in Data Grid in detail.
