传统路由系统以其简单健壮特性很好地完成网络互连和数据传递任务，但面对多样化服务需求，结构固定和功能单一的路由系统显得力不从心。如何在千变万化的业务特性和千差万别的服务需求下提高路由的服务能力成为当前亟待解决的问题。.本课题基于功能分解组合思想，将传统网络服务和路由协议分解为基本功能单元，建立一种新型多态路由模型，通过路由结构的自组织和功能的自调节，实现网络和业务之间的自匹配以及为业务提供定制化服务。.课题着重从三个方面展开研究：一是建立面向多样化服务定制的多态路由模型，提出路由元能力概念，给出路由元能力的数学描述方法，将网络服务和路由能力划分为细粒度网络功能单元；二是分析网络功能组合问题，设计路由元能力的编排和服务路径选择机制；三是研究多态路由原型系统，对多态路由理论和技术进行验证。.通过本课题的研究，将进一步提高网络多样化服务能力，为新型网络体系研究提供切实可行的理论基础和指导。

The traditional routing system well completes the task of network interconnection and data transfer for its simple and robust characteristics. However, in the face of diverse service requirements, the routing system of rigid structure and single function is powerless. How to improve the service ability of the routing system indifferent business characteristics and the changing quality of the service demand has become an urgent problem to solve..Based on decomposition and composition, the traditional routing protocols and network services are divided into the basic functional units, called routing atomic capacities. The customized polymorphic routing protocol is derived through the composition of different routing atomic capacity instances. The key of polymorphic routing model consists of three parts. The first is the description of routing service requirement, called routing service description, which expresses the requirements of applications desired by PR model. The second is base state routing which is the set of routing atomic capabilities. The third is the polymorphic derivation, which is the key to realize from the base state routing to the polymorphic routing. The model enables the network to self-adjust routing services dynamically to adapt to the different requirements of applications,supports coexistence of multiple routing modes and communication paradigms..In detail, three aspects are involved. Firstly, we design the polymorphic routing model for customized diverse services; present the conception of routingatomic capabilities and provides the method of mathematical expression. Secondly, we analyze the problem of the function composition， and design the function orchestration mechanism. Thirdly, we focus on the polymorphic routing prototype system which can support the coexistence of different network architectures and routing protocols. Based on the prototype system, we verify the theory and technology of the polymorphic routing..Based on our researches, the diverse service providing capabilities of the network would be improved, which could provide a feasible academic support for the research of the future network architecture.
