Each module receives and detects the service request, and when there is a corresponding service providing function in its own module, it sends a response back to the requesting module. Among a plurality of nodes, a selection function module which stores service providing function arrangement information of other nodes and determines a node which has the function for the corresponding service request is provided. The selection function module sends back a response to the service request.
