基于策略的QoS协商机制研究

Research on Policy-Based QoS Negotiation Mechanism

随着用户对端到端QoS要求的提高以及服务等级协定SLA的概念的提出,用户迫切需要和业务提供商进行QoS协商.实现动态SLA机制的关键就是设计相应的QoS协商机制.为此,在研究不同网络QoS实现机制的基础上,提出了一种基于网络策略管理的QoS协商机制框架.该系统模型可以灵活、方便的实现动态SLA机制.

With the increase of end-to-end QoS demand and the appearance of SLA concept,customers expect to have a QoS negotiation with their service provider.Since the key to realize the dynamic SLA mechanism is to design the corresponding QoS negotiation mechanism,the frame of QoS negotiation mechanism based on policy management is presented after studying their various realization mechanisms.The newly-established model can easily realize the dynamic SLA mechanism in a flexible way.
