摘要
现有互联网具有"三重绑定"特征,即:服务的"资源和位置绑定"、网络的"控制和数据绑定"及"身份与位置绑定".这种网络体系与机制是相对"静态"和"僵化"的,在此基础上的演进与发展无法从根本上满足信息网络"高速"、"高效"、"海量"、"泛在"等通信需求,难以解决网络可扩展性、移动性、安全性等问题,更难以实现网络资源的高效利用、节能等.本文创造性提出了以"三层"、"两域"为典型特征的智慧协同网络体系结构模型."三层"即:智慧服务层、资源适配层和网络组件层;"两域"即实体域和行为域.在"三层"、"两域"体系模型的基础上,分别建立了智慧服务层、资源适配层和网络组件层的基本理论,以在有效解决网络可扩展性、移动性、安全性等问题的基础上,大幅度提高网络资源利用率,降低网络能耗等,显著提升用户体验.
The current Internet has three types of bindings,namely the binding between resource and locators,the binding between control and data,and the binding between identity and locator.The resulting network architecture makes the network being relatively static and rigid.This makes it difficult for the Internet to satisfy the current demands including high-speed,high efficiency,high throughput,and pervasiveness.In addition,this also makes it hard for the network to be scalable and secure,support efficient host mobility,being efficient resource utilization and energy saving.In order to address these issues once and for all,we propose a novel network architecture called smart and cooperative network architecture.The network architecture has three layers,called the smart service layer,the resource adaption layer,and the network component layer.It also has two realms,called the entity realm and the behavior realm.Based on this architecture,we outlined the basic theories of the three layers,respectively,in order to make a future Internet being able to support efficient host mobility,be scalable and secure,being efficient resource utilization and energy saving,and to offer improved user experience.
