新互联网体系下的普适服务机理及关键技术

The Theory and Key Technologies of Pervasive Services Based on the New Generation Internet

随着网络用户的增加,以及人们对网络需求的个性化和多样化,互联网的原始设计架构已经无法满足这种发展趋势,暴露了很多缺陷和不足,例如:各种服务不断涌现,端口号作为区分服务的机制存在不灵活、不安全等弊端;网络资源与服务之间存在着密切的联系,然而互联网没有很好地利用这一联系,需要同时维护资源和服务两套处理系统,浪费了用户的上网时间,也增加了网络资源的消耗;互联网服务分级粒度不精细,无法体现用户的个性化和多样化需求,必须对其服务重新区分等级。针对以上问题,文章给出新互联网体系下的普适服务机理及关键技术,重点阐述新互联网体系下个性化、多样化用户服务的定义、分类和标识的设计。该设计能统一标识和处理各种网络服务,深度挖掘服务和资源之间的联系,并根据用户的需要提供个性化、多样化的服务。

With more and more users and their individual and diverse demands for network, the Intemet＇s original design can not satisfy this trend. Many defects and shortcomings come up; the mechanism of using ports to distinguish services is not convenient and secure due to the rush of different services. There is a close relationship between data and service, but the Intemet does not make use of this relationship well, leading to a waste of users＇ time and network resources. The classification of network service is not accurate, not satisfying users＇ individual and diverse demands. To solve these problems, the theory and key technologies of pervasive services based on the new generation Intemet are suggested. A new definition, classification and identification of network ＇services, which satisfies individual and diversified need, are also given. This new design can universally identify and process different kinds of network services, deeply dig the relationship between service and data, and provide users with individualized and diversified services.
