摘要：

现有的策略管理框架PBNM不仅存在着策略决策点负担过重、容易形成单点瓶颈等缺陷，同时还缺乏与SLA管理的紧密结合和具体实现。在PBNM的基础上，以Diffserv环境为底层，提出了基于策略的分层分域的业务QoS管理模型PBQM，引入了域策略决策点DPDP，增加了SLA管理、QoS监测和基于知识发现的业务恢复等管理模块；并提出了基于策略的SLA到区分服务网络配置的映射算法，该算法能根据SLA自适应地选择网络设备的配置策略，同时也可以进行策略映射的优化。

Abstract:

The existing policy-based management system PBNM not only has many limitations, such as overburden in policy decision point and single point bottleneck, but also lack of the combination and implementation of SLA management. This paper presents a policy-based multi-level and multi-domain model PBQM for QoS management, which is based on DiffServ environment. It introduces dominical policy decision point DPDP, SLA management, QoS monitoring and service resuming module based on knowledge discovering. In addition, it proposes a policy-based algorithm, which realizes the SLA to Diffserv configuration mapping. The algorithm can adaptable configure network devices as well as optimize the policy mapping according to SLA constrains.

Key words: Service management, Policy, QoS management, DiffServ
