SDN体系架构中元模型构建机制

微服务是现代应用架构的新方法，其特点在于将复杂的应用功能分解到离散、独立的服务中，以实现应用方案的解耦，并且各个服务可以单独开发、部署及扩展。应用的变化必然驱动着底层网络的变化，可重构基础网络体系架构旨在通过网络重构机制来弥补网络业务需求与网络基础传输能力之间的差距。融合可重构和软件定义网络技术，提出了一种SDN体系架构中元模型的构建机制，旨在将SDN体系架构中各层的服务以元模型的方式呈现，并且在借鉴AKF三维伸缩模型之后，提出了一种基于正交分解的元模型的构建方法。最后通过理论分析和开发实例，验证了基于正交分解的元模型构建方法的可行性。

Meta model construction mechanism in SDN architecture

Micro service is a new method of modern application architecture,its characteristic is that decomposing the complex applications into discrete,independent service,so that decoupling of applications scheme can be achieved,and the individual service could be developed,deployed and extensioned independently.The change of the application must drive on the change of the underlying network,the architecture of reconfigurable fundamental information communication network aimd to compensate for the network business requirements and network transmission capacity through the network reconfiguration mechanism.A meta model construction mechanism with the SDN architecture for fusion the reconfiguration and software defined network technology was proposed,it aimed to present the services of each layer in the SDN architecture by the form of meta model.And after referencing the AKF scale cube,a kind of meta model building method based on orthogonal decomposition was proposed.Finally,the feasibility of meta model building method based on orthogonal decomposition from the theoretical analysis and development of example was verified.
