6. The dynamic service network creation apparatus of claim 1, wherein in response to a message being received from the netstore apparatus to notify of the occurrence of an error in a network resource that constitutes the service network, the service network topology configuration unit transmits the message to the service management system, requests and acquires a network resource that substitutes for the network resource having the error from the netstore apparatus in response to a service network recreation request from the service management system, and reconfigures a service network using the acquired network resource.

7. A netstore apparatus comprising:

a resource registration unit configured to register resource information provided from is each of a plurality of network resource providers;

a storage unit configured to store the registered network resource information; and

a resource management unit configured to, in response to a request for network resource information required for providing a network-based service over a service network from at least one dynamic service network creation apparatus, look up the requested network resource information in the storage unit, provide the found network resource information to the at least one dynamic service network creation apparatus, and issue a resource allocation reservation request to a plurality of the network resource providers in response to a request for scheduled allocation of at least one network resource for use in providing the network-based service being received from the at least one dynamic service network creation apparatus,

wherein the netstore apparatus is connected to a plurality of the network resource providers in a domain, which indicates a service management area, and the at least one dynamic service network creation apparatus which dynamically configures the service network.

8. The netstore apparatus of claim 7, wherein the resource registration unit receives resource registration from a plurality of smart devices as the network resource providers and includes a control management function and protocol that supports a variety of types of smart devices so as to control a plurality of the smart devices.

9. The netstore apparatus of claim 8, wherein the protocol includes at least one of a simple network management protocol (SNMP), a general switch management protocol (GSMP), a common open policy service (COPS), a simple object access protocol (SOAP), technical report 069 (TR-069), and a diameter protocol.

10. The netstore apparatus of claim 7, wherein the resource allocation reservation request includes time information at which the network-based service is provided and the resource management unit requests a plurality of the network resource providers to allocate network resources corresponding to the resource allocation reservation request such that the network-based service can be provided based on the time information.

11. The netstore apparatus of claim 7, wherein in allocating the network resources in response to a request from the at least one dynamic service network creation apparatus, the resource management unit stores information about how much amount of network resources of each network resource provider is scheduled or allocated to a service requested by which service management system, and performs resource scheduling based on the stored information such that network resources already having been allocated are not used later for a different service request.
