中文摘要: 针对下一代互联网的基本科学问题之一- - 稳定网络体系结构的服务多样性问题,在继承传统互联网体系结构技术精髓的基础上,通过剖析传统互联网服务模型,抽象共性的协议处理机制和模式,建立元服务集合;通过剖析目前有关安全、QoS等方面的技术原理,抽象相应的单元服务模块,建立高级服务集合;通过两个服务集合的扩展,以及建立在此基础上面向应用需求的服务定制,建立了面向下一代互联网发展的可扩展服务模型。基于该新型服务模型,提出了支持服务可扩展的网络体系结构模型,并且初步实现了基于容器的网络节点模型以验证可扩展服务模型和服务可扩展体系结构的可行性。同时,对相应的协议原理进行了深入研究,提出元协议概念,实现了传统协议部署的可编程化。本课题研究成果为解决网络体系结构的相对稳定性与网络服务需求的复杂多变之间的矛盾提供了直接的理论指导。

英文摘要: On one of the basic scientific problems about Next Generation Internet, i.e. the issue of the stable network architecture's service diversity, based on inheriting the technical essence of traditional Internet architecture,the new NGI-oriented service construction model and the architecture model supporting service scalability are proposed by builting the meta-service set based on analyzing the service model of traditional Internet and abstracting the common processing mechanisms and patterns of network protocols, builting the advanced service set based on analyzing the current technical principles of security,quality of service and so on and abstracting corresponding unit service modules,expanding the two service sets and the application-oriented service customization. In order to verify the researches, we implement container-based network node model as the specific implementation of architecture model.Simultaneously, the corresponding protocol principles are deeply researched.The conception of meta protocols is proposed which can support the programming of deployment of traditional protocol.The research achievement can provide theoretical guidance for addressing the contradiction between the relative stability of network architectures and the complexity, variability of network service requirements.
