摘要
针对科学数据网格子系统DAS系统2.0版本不能很好地解决海量数据的传输问题,首先分析了DAS2.0版本中所采用的数据传输技术在处理海量数据传输时存在的不足之处,指出了导致出现问题的原因,然后提出了一个集成FTP,HTTP,SOAP,SOCKET等技术的新的数据传输解决方案,阐述了该传输方案中各个模块的设计和在DAS系统新版本中的实现。该传输方案可以有效地解决不同数据量的数据在网格环境下的传输问题,并且提供了多种传输方式供不同类型用户选择使用,具有有效性、易用性和可扩展性等特点。
According to the problems of the 2nd version of DAS, the subsystem of Scientific Data Grid, which it meets when transferring massive data, the disadvantages of data transferring solution in the 2nd version of DAS are analyzed firstly, and the root causes are also pointed out. Then a novel data transferring solution which integrates the technologies such as FTP, HTTP, SOAP and SOCKET is proposed, and the design and implementation of each module of the new solution in the new version of DAS are introduced too. The new data transferring solution can transfer different amounts of data effectively in the grid environment and provide multiple-choice of data transferring methods for different users. It＇s easy to use, effective and scalable.
