新一代运营系统和软件中基于策略网络管理的策略语言

Policy Language for Policy-Based Network Management in the Next Generation Operation System and Software

为满足基于策略网络管理对策略语言的要求,在TMF(teleManagement forum’s)策略连续体基础上,提出了语言连续体.由于高层策略语言发展相对不成熟,提出了对语言连续体中高层视点策略语言的要求,包括具备一定的分组机制,能够描述流程,且支持有限状态机模型.为了保证语言连续体中策略语义的一致性和连续性,进一步提出了描述策略语义的两个基本原则.通过基于策略的下一代IP计费原型系统的设计和实验,验证了本文观点的正确性和有效性.

To meet the policy-based network management requirements on policy language, a language continuum, based on TMF＇s（teleManagement forum＇s） policy continuum, was proposed. Considering that the development of high-level languages have lagged behind what the policy-based network management demands, the requests for high-level policy languages were presented, including grouping structures, expressive power for the process and a finite state machine model. Furthermore, in order to implement consistency and continuity of a policy in the language continuum, two basic principles when describing policy semantics were also provided. And a policy-based billing prototype for the next generation IP-based network was designed and implemented for validation of the proposed viewpoints.
