摘要
基于GridSphere框架设计实现了海洋信息服务网格Portal,针对海洋信息资源数据量大、复杂多样化和安全性要求高的特点,进行了三个方面的改进:基于角色访问控制实现了权限管理机制;从可用性和可定制两方面,改进GridSphere布局设计;通过预先创建网格服务句柄,减少了从网格服务工厂到实例化的过程,提高了系统效率。实验结果表明改进是成功的。
Ocean information service grid Portal based on GridSphere framework was designed and implemented, aiming at the huge data, complex diversification and high security requirements of ocean information resources. Three improvements were implemented in this paper： Role-Based Access Control （RBAC） mechanism was adopted to achieve the authority management, the layout of GridSphere was improved, from two aspects of usability and customization, then the process from grid service factory to instantiation was cut down to enhance the system efficiency through setting up grid service handle in advance. The experimental results demonstrate that these improvements are successful.
