摘要

A method is provided for remote monitoring and control of device (nodes) in a network system including a gateway device bridging the network system to an external network, wherein the method comprises: maintaining an address mapping table within the network system, the address mapping table comprising a node unique identifier column and node attribute information, receiving an input data packet from the external network at the gateway device, parsing the input data packet into an output request and input data, mapping the input data to a particular node on an internal network connected to the gate way device, transmitting the input data to the particular node, receiving a response from the particular node, generating an output data packet comprising the response from the particular node, and forwarding the output data packet to the external network.
