摘　　要：体系结构在信息系统中起着举足轻重的作用,不仅决定了系统的功能和性能,而且决定了系统的效能和安全,因此,体系结构直接决定着信息系统的先进性.本文在介绍体系结构概念的基础上,对体系结构的发展进行了归纳总结,分析指出体系结构刚性是当前信息系统灵活性和高效能无法兼备的问题本质,提出了以软件定义互连和软件定义节点为特征的新一代软件定义体系结构,基于软件定义体系结构实现了Web服务、口令字恢复和图像识别3种典型系统,对比测试表明,软件定义体系结构系统较传统通用系统性能提升29.4～344.5倍,效能提升13.7～315.4倍,证明了软件定义体系结构的高灵活性和高效能.Architecture plays an important role in information systems.It not only determines the function and performance of a system,but the system efficiency and security as well.Therefore,the architecture directly determines the advanced nature of an information system.On the basis of introducing the concept of architecture,this paper summarizes the development of architecture,and points out that the rigidity of architecture is the essential reason behind why current information systems cannot tradeoff between flexibility and high efficiency.A new generation of software-defined architecture,which is characterized by software-defined interconnections and software-defined nodes,is proposed.Three typical systems,Web service,password recovery and image recognition,are realized based on a software-defined architecture.Compared with the traditional general systems,the comparison tests show that the performance of the software-defined architecture system increased by 29.4 to 344.5 times,and the efficiency increased by 13.7 to 315.4 times,which demonstrates the high flexibility and high efficiency of software-defined architecture.
