Research On Key Technologies Of Cross-Border Service Network

With the rapid development of the sharing economy and the Internet,data enabling and traffic monetizing through Web services opening has gradually become the choice of most companies.These open Web services are distributed throughout the network,spanning boundaries of different industries,organizations,geographies,and value chains.Services within different boundaries are independent of each other.We call these services as cross-border services.Cross-border services are expressed in various forms in the network environment,which makes the realization of service reuse such as cross-border service integration,query,and routing become a problem.At present,the research in the field of cross-border services is still in its infancy.Most of the related researches are proposed for single theoretical research such as service registration and discovery,service composition and service routing.There is no complete solution to the problems related to cross-border services.Combined with the medical service realization scenario.referred to the service architecture evolution,service integration method,existing service network and other related research work,this thesis proposes a cross-border service network as a cross-border service carrier to solve the problem,and studies key technologies about the service network model,query mechanism and service routing mechanism.Aiming at the integration requirements of cross-border services security access,heterogeneous unified and hierarchical management,this thesis proposes a P2P-based hierarchical service network ExtendNet.In the research of service query mechanism,this thesis defines the form of service resources,assigns grammar and semantic attributes,and proposes a query method and index mechanism based on super nodes,which makes the service network have semantic and grammar query capabilities.In the research of service routing,this thesis summarizes the service routing definition and common routing model.Based on the network-aware routing model,a dynamic routing algorithm HRNR based on network resources is proposed.Through comparison experiments,it is proved that HRNR can effectively solve the problem of slow service call due to problems such as network lines.Finally,based on the key technology theory of service network,this thesis implements the cross-border service network prototype system SRN.This thesis introduces the prototype system SRN through the overall architecture of the prototype system,the structural design of the service switch and service router,the service gateway implementation,and the key function display.
