Abstract:
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.
