摘要
目前电力通信业务对承载网络的性能需求不断提高,软件定义光网络(SDON)技术以其开放化和软件化的优势驱动着电力通信与SDON技术的融合,基于传统光传输网建立的指标体系和评估方法无法体现SDON架构的特点和对电力通信网业务承载性能的影响。文章结合电力通信业务的性能需求、影响因素及不同SDON架构对业务性能的影响构建了新的指标体系,根据指标对各属性的贡献度确定决策矩阵,提出有序加权平均—扩展逼近理想解排序(OWA-E-TOPSIS)的多属性决策方法,实现了指标的筛选;用层次分析法(AHP)对筛选出的指标进行权重分配,搜集实例,经效用函数法预处理后,进行指标值聚合,通过对比各实例的评估结果,验证了指标体系和评估方法的可行性,为电力通信网新技术的应用和新业务的支撑提供了依据。
At present,the performance demand of power communication service for bearer network is constantly increasing.Software Defined Optical Network(SDON)technology drives the integration of power communication and SDON technology with its advantages of openness and softwareization.The index system and evaluation method established based on traditional optical transmission network cannot reflect the characteristics of SDON architecture and its influence on bearer performance of power communication network service.In this paper,a new index system is constructed based on the performance requirements,influencing factors and the influence of different SDON architectures on the service performance of power communication business.The decision matrix was determined according to the contribution degree of the index to each attribute.The Ordered Weighted Average-Extended-Technique for Order of Preference by Similarity to Ideal Solution(OWA-E-TOPSIS)multi-attribute decision making method was proposed to realize the index screening.The weight distribution of the selected indicators is carried out by Analytic Hierarchy Process(AHP),and the examples are collected.After the pretreatment by utility function method,the index value aggregation is carried out.By comparing the evaluation results of each instance,the feasibility of the index system and evaluation method are verified,which provided a basis for the application of new technology and new business support of electric power communication network.
