The system has been established by adopting the Browser/Server structure, with the TRS software as the platform of database and the ASP, JSP techniques as the generation methods of dynamic web pages. Consisting of two platforms: the user platform and the manager platform, the system has achieved the modules of browse, retrieval, supply and management of information.
The management of permission in the Role-Based Access Control(RBAC) 2001 model is studied in this paper. Aiming at problems of this model,the conception of object_group is introduced into the traditional model of permission,and the model of permission based on object_group is constructed. Then,a new RBAC model based on object_group(GB-RBAC)is presented,which makes the operation of administrators easy and implements the dynamic management of permission in time.
However, in many practical situations, a manager may control processing time by reallocating resources.
The purpose of this paper is to discuss how the value of high-tech firm can be rationally valued by taking into account managerial flexibility when its future revenue is uncertain, thereby the firm's manager can make rational investment decisions.
Research on switching throughput of traffic manager in core routers
A general model is made to analyze switching throughput of traffic manager in core routers.
By designing a real traffic manager that uses the OC-48c interface, the whole system is analyzed and it is pointed out that at least four HSSLs should be employed per CSIX interface when using Vitesse's GigaStream switch chipset.
