摘　　要：随着软件定义网络(Software-Defined Networking,SDN)逐步朝向大规模的方向发展,SDN管理层信息模型的描述域与SDN基础设施层信息模型的描述域之间可能出现SDN管理信息的语义不匹配问题.可拓论建立了形式化和规范化描述信息与知识的一种新模型,为研究解决SDN管理信息的语义不匹配问题提供了一种可行方案.首先提出SDN管理信息的基元表示,然后对其进行可拓变换,最终从形式化的角度研究解决SDN管理层与基础设施层之间存在的管理信息语义不匹配问题.实例分析结果表明,应用可拓论研究SDN管理信息的基元表示与可拓变换,为SDN体系结构演化及其网络管理大规模发展建立一定的信息表示基础.Since Software-Defined Networking(SDN)is gradually under the direction of large-scale development,the semantic-mismatching problem of management information for SDN may exist in both domain descriptions of management information for SDN management layer and SDN infrastructure layer.The extension theory,as a new model for the formal description of information and knowledge,provides a feasible method for the study of the semantic-mismatching problem of management information for SDN.First the representation of management information for SDN is proposed using basic-elements,and then the extension transformations are performed.Finally the semantic-mismatching problem of management information for SDN between the management layer and the infrastructure layer is studied and solved from the formal viewpoint.Results of example analysis show that application of extension theory in the study of management information for SDN using basic-elements and extension transformations aims to establish a certain foundation of information representation for evolution of the SDN architecture and its large-scale development of network management.
