Automatic functionality generating mechanism for network connecting appliances

摘要

To provide a system enabling a function for implementing providing of a service desired by an end user to be automatically generated in a network connecting appliance. When a resource server (RS) receives a request for a specification which is desired to be implemented from a particular service adapter (SA), the requested specification is analyzed by a specification analyzing device, a virtual service adapter is formed by collecting functional modules required to implement the specification, and the formed virtual service adapter is provided for the requesting service adapter. The virtual service adapter is automatically set as a physical service adapter to implement an actually requested function in a service adapter at an end user's place.
