基于贝叶斯网络的互联云QoE评价模型

Intercloud QoE Evaluation Model Based on Bayesian Networks

为了避免发生云间服务不兼容等服务质量下降问题,构建了一个基于贝叶斯网络的互联云用户主观满意度评价模型。该模型部署在应用云服务端,使得云服务提供商可以根据QoE评价选择互联云合作方案,以较小的成本达到用户QoE权益最大化。

In order to avoid the problem of service quality degradation such as incompatibility between cloud services,this paper constructed intercloud QoE evaluation model based on Bayesian network which reflects the users’subjective satisfaction.The model is deployed on the application cloud server,makes the intercloud service providers choose the appropriate cooperation scheme based on QoE evaluation,to maximize the rights and interests of the user’QoE with lower cost.
