CGSP2.0中域管理服务设计与实现

Domain manager service design and implement in CGSP2.0

针对CGSP2.0中网格域的特点,设计和实现了域管理器.它负责CGSP中每一个自治域的管理,功能包括用户管理、组管理、身份映射管理与系统级服务管理四部分.CGSP中域管理器通过用户映射来实现虚拟组织的建立,将虚拟组织的管理与物理组织管理统一起来,简化了网格系统的设计.通过域管理器,CGSP可以支持网格虚拟组织安全、高效的管理与跨域访问.实验表明域管理器能够很好的满足多用户并发的操作请求,多用户查询的平均时间开销不会随着用户数的急剧增加而明显加大,系统保持稳定良好的性能.

According to the character of the domain of CGSP2.0, the Domain Manager was implemented.It is a management module of autonomous,which is responsible for user management,group management,mapping policy management and Sys-service management of each domain.In CGSP,Domain Manager can set up grid virtual-organizations by mapping policy.It unifies the virtual-organization management and physical-organization management,and so simplifies the design of grid system.By using Domain Manager,CGSP can support grid virtual-organization management and across-domain accessing securely and effectively.The experiment results show that Domain Manager can response the users′ concurrent requests effectively,the average searching time won′t change obviously while the number of users sharply rises,and the system has high and steady performance.
