gFDT:用于数据网格的高速数据传输模块

数据网格中的数据具有分布的、异构的和海量的特点。这使得数据的复制和迁移既不同于局域网内的数据传输特性,又有别于广域网上的数据传输要求。因此,我们希望针对数据网格对数据传输的需求,构建一个可以与数据网格良好整合的传输模块。本文在分析了现有数据网格中数据及其传输的特点以后,提出并实现了一个用于数据网格环境的可同时支持多种数据传输协议的客户端数据传输模块。通过在实际的网格环境下进行的测试表明本模块可有效提高数据网格的数据传输速度。

gFDT:Fast Data Transfer Module for Data Grid

There are distributed, heterogeneous and large scale features born with data which is stored in data grid, which makes data replication and movement different from local area network or wide area network. In order to match this request, we hope to develop a data transfer module that can be integrated into data grid environment seamlessly. This paper analyzes those characterristics and brings forward gFDT (grid Fast Data Transfer) which can supports popular different protocols. We implement gFDT and use it as client to do data transferring experiments. And the experiment results show that gFDT can improve data transfer speed effectively.
