【摘要】 如何在分布式环境中灵活配置QoS参数成为一个值得关注的问题,目前用户对QoS的管理主要还是利用手工的静态配置和简单的策略管理,尚不能很好地适应网络规模的扩大以及设备的多样化。由此,提出了一个智能代理的内部基本模型,并在此基础上设计并实现了一个针对服务质量保证的智能代理实体模型,该模型包括智能代理对流量分布规律的分析、预测和配置功能以及代理之间的交互机制。原型系统的实验结果表明该模型可以有效地提供服务质量保证。更多还原

【Abstract】 How to implement the configuration of the QoS parameter flexibly in distributed computer network has be-come a problem to be envisaged due to the weak scalability of current approaches. In effort to solve this problem, an in-ner basic model of intelligent agent (IA) was presented and extended by introducing the mobility firstly, and a QoS guar-antee scheme was designed and implemented based on the model subsequently as well. By utilizing the proposed scheme, the IA can sense, predict and configure the traffic. Since the ability of negotiation was also considered and provided, the competition among different devices could be eliminated effectively and the global traffic can be optimized. The results of the simulations show that the proposed model can provide QoS guarantee remarkably.更多还原
