Service flow central processing unit and service flow treatment manner

摘要

A service flow processing apparatus requests a service on a network to perform processing in accordance with a service flow description document and an interface description document, and receives a response from the service. The service flow processing apparatus also generates a proxy service that corresponds to the service, and if a normal response has not been received from the service, the service flow processing apparatus changes the destination of the request for the service described in the interface description document to the proxy service.
