RELAY DEVICE, COMMUNICATION SYSTEM, AND METHOD OF ACQUIRING NODE SETTING INFORMATION
First Claim
1. A relay device connected to a node comprising:
- at least one physical port connected to the node and a processor,when receiving an address acquisition request which is a request for acquiring an address to be set in the node from the node through the physical port, the processor transmits, to the node, an address acquisition reply including the address to be set in the node, node information identifying the node that has transmitted the address acquisition request, and an address of the setting information storage device that stores setting information of the node through the network, transmits, to the setting information storage device, a setting information acquisition request which is a request that the node has transmitted to acquire setting information of the node and which includes the node information with the address of the setting information storage device set as a destination, and transmits, to the node, setting information which corresponds to the node information included in the setting information acquisition request and which is transmitted from the setting information storage device.

Abstract
A relay device connected to a node and connects the node to a network, wherein, when receiving an address acquisition request through a physical port, the relay device transmits, to the node, an address acquisition reply including an address to be set in the node, node information identifying the node that has transmitted the address acquisition request, and an address of the setting information storage device which is connected to the network and configured to store setting information of the node, transmits, to the setting information storage device, a setting information acquisition request which is transmitted with an address of the setting information storage device set as a destination and which includes the node information, and transmits, to the node, setting information which corresponds to the node information included in the setting information acquisition request and which is transmitted from the setting information storage device.

7. A communication system comprising:
-
a node; and a relay device that connects the node to a network, wherein the relay device has at least one physical port connected to the node, the node is configured to transmit an address acquisition request which is a request for acquiring an address thereof, when the relay device receives the address acquisition request from the node through the physical port, the relay device transmits, to the node, an address acquisition reply including the address to be set in the node, node information identifying the node that has transmitted the address acquisition request, and an address of a setting information storage device which is connected to the network and configured to store setting information of the node, when the node receives the address acquisition reply from the relay device, the node sets the address therein based on the received address acquisition reply and transmits, to the relay device, a setting information acquisition request which is a request for acquiring the setting information of the node and which includes the node information included in the received address acquisition reply with the address of the setting information storage device included in the received address acquisition reply set as a destination, when the relay device receives the setting information acquisition request from the node, the relay device transmits the received setting information acquisition request to the setting information storage device and, when receiving, from the setting information storage device, the setting information corresponding to the node information included in the setting information acquisition request, transmits the received setting information to the node, and when the node receives the setting information from the relay device, the node executes setting processing therefor based on the received setting information. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method of acquiring setting information of a node in a communication system including the node and a relay device that connects the node to a network,
the relay device being connected to a setting information storage device that stores setting information of the node through the network and having at least one physical port connected to the node, the method comprising the steps of: -
transmitting by the node, an address acquisition request which is a request for acquiring an address thereof; when the relay device receives the address acquisition request from the node through the physical port, transmitting, by the relay device, to the node, an address acquisition reply including the address to be set in the node, node information identifying the node that has transmitted the address acquisition request, and an address of the setting information storage device connected to the network; when the node receives the address acquisition reply from the relay device, setting, by the node, the address therein based on the received address acquisition reply and transmitting, by the node, to the relay device, a setting information acquisition request which is a request for acquiring the setting information of the node and which includes the node information included in the received address acquisition reply with the address of the setting information storage device included in the received address acquisition reply set as a destination, when the relay device receives the setting information acquisition request from the node, transmitting, by the relay device, the received setting information acquisition request to the setting information storage device and, when receiving, from the setting information storage device, the setting information corresponding to the node information included in the setting information acquisition request, transmitting, by the relay device, the received setting information to the node, and when the node receives the setting information from the relay device, executing, by the node, setting process of the node based on the received setting information.
