深入研究了Globus 工具包中數據傳輸模型的結構、實現細節和特點，在此基礎上吸
取它的優點，提出了一個新的與Globus 工具無關的數據傳輸模型。該模型立足于為用戶提供方便的使用模式，屏蔽系統的異構性，同時也考慮了傳輸性能和負載均衡等問題。

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 .
