doi:10.3778/j.issn.1002-8331.2111-0525

Abstract

Abstract: The SDN-enabled cloud computing platform has gradually been used widely, and more and more attention has been paid to the quality evaluation of services provided by SDN-enabled cloud computing platform. Firstly, the general cloud service and the software-based characteristics of SDN-enabled cloud computing platform services are considered. From the perspectives of service providers and users, the design requirements of service quality model are analyzed, and the categorical dimensions of service quality model are obtained. Then, referring to SQuaRE international standard, the service quality model QM-SDNCCP of SDN-enabled cloud computing platform is established, and the calculation method of the metrics is given. Furthermore, the purpose of describing and quantifying the service quality of SDN-enabled cloud computing platform is achieved. Finally, the reliability analysis of QM-SDNCCP is carried out, which shows that the design of QM-SDNCCP model characteristics and sub-characteristics are reliable and consistent, it means QM-SDNCCP can be applied in the stages of technology selection, acceptance, operation and service management and also it can be used to guide on selection of cloud platform service and quality improvement by service providers and users.

摘要： 基于SDN的云网平台逐渐得到广泛应用，云网平台所提供服务的质量评价也越来越受到关注。考虑了云网平台服务所具有的通用云服务和软件化的特点，从服务提供者和用户两个视角出发，对服务质量模型的设计进行了需求分析，并获得服务质量模型的分类维度；参考SQuaRE等国际标准，提出了云网平台服务质量模型QM-SDNCCP，并给出了度量元的计算方法，以达到描述并量化评价云网平台服务质量的目的；对QM-SDNCCP进行了信度分析，表明QM-SDNCCP模型的特性和子特性的设计具有可靠性和一致性。QM-SDNCCP可以应用在技术选型、验收、运维和服务使用阶段，为服务提供者和用户提供云网平台服务选择和质量改进的参考。
