深入研究了Globus 工具包中数据传输模型的结构、实现细节和特点,在此基础上吸 取它的优点,提出了一个新的与Globus 工具无关的数据传输模型。该模型立足于为用户提供方便的使用模式,屏蔽系统的异构性,同时也考虑了传输性能和负载均衡等问题。 关键词:数据传输模型,Web Service ,异构性,GridFTP Abstract: Some thoroughly research on the data transfer model in Globus Tloolkit is introduced in this paper, it contains the following aspects :the architecture、the detail of the realization and the trait, on the foundation of these research some virtue are extracted, a new data transfer model which has no relationship with Globus Toolkit is presented. The model is established in providing convenient use mode for the client ,shielding the heterogeneity of the system , in the meantime ,transfer performance and load balancing has also been considered .
