Dynamic late binding of third party on demand services in an on-demand infrastructure

摘要

The present invention relates to the field of networked computer and refers to a method and respective system for providing on-demand services via an electronic network from a service provider (SP) to a client requesting a service, wherein a plurality of third-party service providers (TPSP) are involved for providing one or more on-demand services (called TPSP service) as a possible contribution to said client-requested service. In order to simplify the selection of a TPSP service for being provided by the SP, the following steps are proposed:a) calling (710) a Meta Service Selector (MSS) to select the best TPSP service according to a predetermined evaluating scheme referring to predetermined evaluation attributes and a predetermined evaluation algorithm,b) sending (730) an enquiring request enquiring respective request properties of a TPSP service to a TPSP, wherein the enquiring request demands the enquired service property information to be delivered formatted according to an interface data scheme agreed on between the enquiring SP request and said TPSP service,d) evaluating (775) the enquired information from said plurality of TPSPs according to a predetermined rating (780) scheme,e) selecting (785) a particular TPSP service for providing it via an electronic network to a service requesting client of the SP.
