Patent ID: 8892777

Claim:
A method for transmitting an address of a first network device from the first network device through a network node to a second network device, the first network device and the second network device being located in different subnets, the method comprising: receiving, by the network node, a first request signal from the second network device, the first request signal including a first request identifier and a request for the address of the first network device; creating, by the network node, a second request signal, the second request signal including the request and a second request identifier; sending, by the network node, the second request signal to the first network device; receiving, by the network node, a first response signal as a response to the second request signal, the first response signal including the address of the first network device and the second request identifier; and sending, by the network node, a second response signal to the second network device as a response to the first request signal, the second response signal including the address of the first network device and the first request identifier; wherein the first request signal, the second request signal, the first response signal and the second response signal are signals of the Discovery and Basic Configuration Protocol (DCP protocol) in accordance with a second layer of an Open Systems Interconnection (OSI) model.
