【摘要】：针对新型网络及其服务构建中所涉及的网络组件选择问题,以可信评估思想为指导,通过多属性决策建模,提出一种网络组件性能评估方法。首先,针对网络应用环境的灵活多变特征,设计了一种按需驱动的可信指标树动态构建策略。其次,利用模糊层次分析法减小主观权重计算的不确定性,并将主客观权重相结合以提高赋权操作的公平性。最后,在评估决策阶段,综合运用指标数据效用转换、可信属性向量构造和向量间的相对近似度计算等策略得到评估结果。通过对软件定义网络控制器的实际案例分析,验证了所提评估方法的合理性及有效性。
[Abstract]:Aiming at the problem of network component selection in the construction of new network and its services, a network component performance evaluation method is proposed based on the theory of trusted evaluation and multi-attribute decision modeling.Firstly, according to the flexible and changeable characteristics of network application environment, a dynamic construction strategy of trusted index tree driven by demand is designed.Secondly, the fuzzy analytic hierarchy process is used to reduce the uncertainty of the subjective weight calculation, and the subjective and objective weights are combined to improve the fairness of the weighting operation.Finally, in the stage of evaluation decision, the evaluation results are obtained by using the strategies of index data utility conversion, credible attribute vector construction and relative approximation between vectors.The rationality and effectiveness of the proposed evaluation method are verified by analyzing the actual cases of the software defined network controller.
