A Dynamic Service Discovery and Publishing Method for Heterogeneous Networks

Abstract

A heterogeneous network dynamic service discovery and release method disclosed by the present invention aims to provide a method capable of improving the interoperability and universality of service discovery and release among heterogeneous networks. The present invention is realized through the following technical solutions. In a heterogeneous network environment, the proxy gateway operating engine module is used as the operating carrier of the entire gateway function to periodically perform service discovery, release and logout on each heterogeneous network domain; The service discovery mechanism of each domain is invoked in the network to discover the current active services of each domain; compare the discovered service with the gateway cache, convert the newly discovered service into a comprehensive service description model and add it to the service cache; and then pass Protocol conversion converts the comprehensive service description into a service description that conforms to other domains, and encapsulates it into a service release message in other domains for publication; if there is a service that belongs to the cache but does not belong to the current discovery service set, it will be deleted through the service cancellation mechanism of other domains .

Description

technical field [0001] The present invention relates to a dynamic service discovery and release method mainly applied in a heterogeneous network environment, which is used to perform services provided by various heterogeneous networks (such as wired networks, wireless networks, manned platforms or unmanned aerial vehicles platforms, etc.) Dynamic discovery and publishing, especially in the field of service-oriented architecture implementation and technology development in heterogeneous environments. Background technique [0002] Web service discovery is an important part of the Web service system architecture and one of the key technologies in the development of Web services. Web service discovery means that users find the services they need in different types of Web services in a certain way to execute Web service requests. The existing Web service discovery methods are divided into: syntactic level service discovery and semantic level service discovery. Semantic-level se...
