一种基于用户感知的灰联度分析QoS映射方法

摘要

With the rapid development of network integration, how to make the reasonable and effective QoS mapping in heterogeneous net works to satisfy users' services becomes an important issue to be resolved immediately. This paper analyses the difficulties and insufficiencies of existing QoS mapping method in heterogeneous network, proposes the user's quality of experience-based GRQM mapping algorithm on SLA structure, which uses the gray relational analysis to obtain the bearer network QoS index combination with largest closeness degree on user's quality of experience, so as to achieve the services of precise quantitative QoS mapping and QoS guarantee.%随着网络融合的迅猛发展,如何在异构网络间进行合理有效的QoS映射使用户获得满意的服务成为当前急需解决的问题.通过分析现有异构网络中QoS映射方法的难点与不足,在SLA架构上提出一种基于用户感知QoE的GRQM映射算法,采用灰关联分析的方法获取与用户感知有最大贴近度的承载网络QoS指标组合,从而实现业务QoS的精确映射和切实保障.
