商用的Internet中资源和服务以商品的形式出现,因此引入定价机制对解决资源分配问题将产生重要作用.把资源竞争过程中的竞争者抽象为用户、网络节点和ISP,分别分析了价格对其QoS的影响,建立了优化模型.提出了一个基于智能代理的简单且灵活的优化框架,使得实际网络中资源竞争者能够对价格的变动作出合理的反应,从而提高了整个网络的QoS.
The resources and servies of the Intemet have appeared in commodity form. Therefore pricing mechanism will play an important role in solving the problem of resource allocation. The competitors can be abstracted into three parties: users, network nodes and ISPs when allocating the resources. This paper analyzes the effect of pricing on QoS and establishes optimization models for them respectively. A simple and flexible optimization framework based on intelligent agents is presented, which can lead the competitors on the Interet to react rationally to the fluetuation of prices. Consequently, the QoS of the whole network can be improved.
