A Research And Implementation On Service-Based Client Engine

After the Internet using in commercial, the scale of network has seen explosive growth. The habits of Internet users are also changing. Traditionally users use the network to transmit data by the end-to-end communication mode. But now they more care about accessing to content services. In order to adapt to the sustainable development of the Internet in the future, it is need to strengthen the physical network to be more manageable and controllable to meet different service needs of different-users. The service has two meanings:the first meaning is the service content itself; the second meaning is physical network allocating network resource according to the need of different service. The existing research of service oriented network tends to set a resource on the Internet as a service. Flattening concept of the service lacks of more connotation.Besides the name, format and data itself, the service need more attributes, For example, the service requester, the QoS needs, service fees, security, authority, etc. Establishment of service model can standardize specification service and users can get more useful information when searching for service. This paper proposes to establish semantic service model, and use concept of resources, properties, statements to describe service. Based on semantic service model as the foundation, Logic inference mapping are using to come to meet the specific needs of service according to the service rules when user request service.This paper is divided into four parts:Firstly, this paper briefly introduce the research status of the future network and some network technologies. Secondly, this paper proposed service oriented network service network architecture including service parse, virtual network mapping, perception forecast and communication process of the service network.Thirdly, this paper the established semantic service model of according to the characteristics of service network. So the service has formal machine understandable semantics.On this basis, it needs a logical derivation to map services when user initiates a request and get a differentiated services identification to parse in the underlying network.Fourthly, the paper describes client service engine architecture, the development environment and the function of main modules.
