摘要
现有信息网络的原始设计思想基本上是一种网络支撑一种主要服务的解耦模式,难以满足网络和服务的多样性需求.本论文从现有多种信息网络存在的严重弊端出发,研究和探索新一代信息网络体系的基础理论,给出一体化网络与普适服务新体系结构模型;创造性地提出新网络体系下的网络一体化模型与理论,建立接入标识、广义交换路由标识及其映射理论;提出普适服务体系模型与理论,创建服务标识及其映射理论、连接标识及其映射理论;最后通过原型系统对上述机理、原理及理论进行验证,实验结果表明,这种新的网络体系在有效地解决现有网络安全、移动、异质异构等弊端的同时,可支持普适服务.
Due to historical reasons,the original model of existing information networks is that one network corresponds to one main service, and this mode can＇ t adapts well to increasing multi-demands of networks and services. In this paper, we study the new information network architecture to address the serious shortcomings of existing information networks. First we give a new framework of Universal Network and Pervasive Services, which includes two layers： Network Communication Layer and Service Layer. Second we propose the basic model and theory of Universal Network, including accessing identifier, switching-routing identi- fier and mapping mechanism between them. Third we bring forward theory and mechanism of Pervasive Services, including service identifier and its parsing theory, connecting identifier and its parsing theory. In the end, we develop the prototype system and validate responding theories. Results show that our new network architecture overcomes shortcomings of existing information networks in mobility,security and so on.Also,the new network system can support pervasive services perfectly.
