Network management has steadily evolved from centralized paradigms to distributed and intelligent paradigms.Many technologies have applied to this field.In this paper,we analized all the paradigms in details in three aspects:the computation schema ,the delegation granularity,and the semantic richness of the information model.It is very useful for the network administrators to design a management application.

网络管理体系结构从当初的集中式体系,向分布化、智能化发展,采用的网络管理技术更是层出不穷,众说纷纭。该文对网络管理的体系结构和其中的技术从计算思想、委托粒度、信息模型的语义三个方面作了深层次的剖析。有助于设计者在分析和设计网络管理应用时选取合适的体系结构和技术。

Delegation is an important secure policy that RBAC should support. Most Existing RBAC delegation models cannot effectively support fine delegation granularity and controllable propagation of permissions. This paper first introduces the concept of quantified-role and then proposes a fine-grained delegation constraint mechanism. Lastly, it gives a formal Quantified-role Based Controllable Delegation Model (QBCDM). The model supports the delegation of any part of permissions of roles, while avoiding incurring high administrative cost. It also provides mandatory constraints and fine-grained discretionary constraints, which ensure the constringency of delegation ability in multi-step delegations and significantly enhance controllability of delegation.

针对现有RBAC委托模型在支持细致委托粒度和权限传播的可控性上存在的不足,提出了量化角色的概念,实现了一种细粒度的委托约束机制,给出了一个形式化的基于量化角色的可控委托模型QBCDM(Quantified-roleBasedControllableDelegationModel).该模型提供了灵活的委托粒度,支持对角色任意部分权限的委托,避免了引入较高的管理代价;支持强制委托约束和细粒度的自主委托约束,保证了多步委托过程中委托能力的收敛性,显著增强了委托过程的可控性.
