可重构信息通信基础网络端到端模型的研究与探索

Research on End-to-End Model of Reconfigurable Information Communication Basal Network

作为一种革命式的未来互联网体系结构,可重构信息通信基础网络通过构建并存的虚拟网支持不同的业务类型,通过多态路由机制支持按需配置的寻址方式。为了适应多样性的端系统以及持续变化的底层网络环境,需要以柔性、可扩展的方式有效地管理资源,提供端到端服务。针对这一需求,提出了一种数据面水平分层、管理面垂直分层的二维端到端模型。该模型利用agent的环境感知、自主决策和交互协作能力,实现域内和域间资源、服务、虚拟网、服务路径的自治管理。为了将端系统纳入自治管理框架,设计了新型的端系统体系结构,并提出了端系统到虚拟网的接入机制,实现了自动的通信连接和服务提供。

As a clean-slate future Internet architecture,the reconfigurable information communication basal network supports various business types via constructing co-existing virtual networks and implements on-demand addressing by polymorphic addressing and routing mechanism.To serve the diversified end systems and to respond to the continuous changes of the underlying network environment,resources and end-to-end services need to be managed and provided respectively in a flexible and scalable way.To this end,a two-dimensional end-to-end model was proposed with the horizontal dimension corresponding to the data plane and the vertical dimension corresponding to the management plane.It achieves intra-domain and inter-domain autonomic management of resources,services,virtual networks and service paths based on the agents＇ capabilities of awareness,self-decision making and interacting with each other.To incorporate end systems in this autonomic management framework,a novel end system architecture was designed and an end system access scheme was proposed,which eventually enables automatic connections to virtual networks and automatic service provisioning.
