深入研究了Globus 工具包中數(shù)據(jù)傳輸模型的結(jié)構(gòu)、實(shí)現(xiàn)細(xì)節(jié)和特點(diǎn)，在此基礎(chǔ)上吸
取它的優(yōu)點(diǎn)，提出了一個(gè)新的與Globus 工具無關(guān)的數(shù)據(jù)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(tǒng)的異構(gòu)性，同時(shí)也考慮了傳輸性能和負(fù)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 .
