摘　　要：传统僵化单一的路由机制已经无法适应未来多样化的业务需求和各种新型网络体系结构的试验与部署.针对此问题,本文基于路由功能与业务需求自适配的思想提出了多态路由模型,并设计实现了多态路由原型系统.该系统通过虚拟化技术以及灵活可编程的数据平面结构,实现了同构和异构网络中多种路由协议的共存,完成了基于路由服务描述的路由协议个性化定制和数据平面的多表选择查询与转发处理.最后,基于Net FPGA-10G平台设计实现了多态路由原型系统.相较于现有路由试验系统,多态路由系统在实现路由协议定制化及异构网络共存的同时,更好地保证了业务的服务质量,具有更高的转发速率以及可扩展性.The traditional rigid routing mechanism has been unable to meet the various service demands and the de- ployment of new network architectures in future. Aimed at this problem, this paper proposes the polymorphic routing model which is based on the adaptation between routing function and service requirements, and implements the polymorphic routing prototype. The prototype supports the coexistence and customization of a variety of routing protocols in both homogeneous and heterogeneous networks through the virtualization technology and the selective data plane for query and forwarding. Fi- nally ,the prototype was implemented based on the NetFPGA-10G platform. Compared with the existing routing systems ,the polymorphic routing system realizes the coexistence and customization of various routing protocols, and achieves higher for- warding rate ,better scalability and insurance of the quality of service at the same time.
