Web service based distributed file service system, which is based on web, xml, and soap and built on hierarchical cache management, distributed mass-storage data management, access control, has a good extensibility, flexibility, reliability and security on the management system of enterprise's mass file date 基于webservice構(gòu)架的分布式文件服務系統(tǒng)基于web、xml和soap技術(shù)、以及層次式緩存管理、分布式海量數(shù)據(jù)管理、訪問控制等等多項技術(shù),系統(tǒng)實現(xiàn)了企業(yè)級海量文件數(shù)據(jù)管理系統(tǒng)對可擴展、柔性、全分布、可靠、安全等幾方面需求的支持。
In the 4th chapter, we discuss the problems in the implement of the web service based distributed file service system . it focuses on four problems : the design of central control unit, the policy of mass storage in local file service unit, the parallel access control algorithm and hierarchical cache management mechanism 論文的第四部分介紹了基于webservice的分布式文件服務系統(tǒng)在應用實現(xiàn)中需要考慮的許多方面的問題,構(gòu)造出針對四個方面問題的算法模型:集中控制單元設(shè)計模型、海量文件的本地存儲策略、文件并發(fā)訪問控制算法和分層的緩存管理機制。
