Evaluation of Service Bearing Performance of SDON Optical Transmission Network in Electric Power Communication
Abstract
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.
