First Claim
Patent Images
1. A method of discovering a component in a sub-network, the method comprising:
- receiving first information on at least one component included in a first sub-network of a network, and second information on the first sub-network, by a first component when the first component joins the first sub-network;
determining whether other information which identifies the at least one component exists in a storage space for the second information;
determining whether the other information comprises the first information when the other information exists in the storage space;
updating the other information in the storage space with the first information when the other information in the storage space does not comprise the first information; and
broadcasting the first information to all components included in a second sub-network of the network by the first component to enable all the components included in the second sub-network to discover the at least one component included in the first sub-network if the first component joins the second sub-network,wherein the first information comprises an Internet protocol (IP) address of the at least one component included in the first sub-network.

14. An apparatus for discovering a component in a sub-network, the apparatus comprising:
-
a receiving unit which receives first information on at least one component included in a first sub-network of a network, and second information on the first sub-network, when the apparatus joins the first sub-network; a storage unit which determines whether other information which identifies the at least one component exists in a storage space for the second information, and determines whether the other information comprises the first information when the other information exists in the storage space, and updates the other information in the storage space with the first information when the other information in the storage space does not comprise the first information; and a control unit which broadcasts the first information to all components included in a second sub-network of the network to enable all the components included in the second sub-network to discover the at least one component included in the first sub-network if the apparatus joins the second sub-network, wherein the first information comprises an Internet protocol (IP) address of the at least one component included in the first sub-network. - View Dependent Claims (15, 16, 17)

18. A method of discovering a component in a sub-network, the method comprising:
-
receiving first information comprising an Internet Protocol (IP) address on at least one component included in a first sub-network of a network, and second information on the first sub-network, by a local information center when the local information center joins the first sub-network; determining whether other information which identifies the at least one component exists in a storage space for the second information; determining whether the other information comprises the first information when the other information exists in the storage space; updating the other information in the storage space with the first information when the other information in the storage space does not comprise the first information; and broadcasting the first information to all components included in a second sub-network of the network by the local information center to enable all the components included in the second sub-network to discover the at least one component included in the first sub-network if the local information center joins the second sub-network, wherein the broadcasting of the first information to the second sub-network comprises; acquiring connection status information of the at least one component; updating the first information using the connection status information; and broadcasting the updated first information.
