Network system that connects a network terminal to another network terminal having a different protocol
First Claim
1. A network system comprising:
- a plurality of network terminals connected to a network, each of the plurality of network terminals having an IP address different from one another; and
an administrator terminal connected to the network to manage the plurality of network terminals; and
a gateway, provided between the network and the administrator terminal, for restricting direct communication between the administrator terminal and the plurality of network terminals and allowing the administrator terminal to directly communicate with one of the plurality of network terminals, whereinthe administrator terminal includes;
a finding unit that causes the one of the plurality of network terminals to research information as to another of the plurality of network terminals that is capable of communicating directly with the one of the plurality of network terminals;
a determination unit that determines based on the information whether the another of the plurality of network terminals has a first IP address that is allowed by the gateway to directly communicate with the administrator terminal;
a transmission unit that transmits a command to the one of the plurality of network terminals, the command being for changing an IP address of the another of the plurality of network terminals to a different IP address that is allowed by the gateway to directly communicate with the administrator terminal, if the determination unit determines that the another of the plurality of network terminals does not have the first IP address; and
a direct communication unit that establishes direct communication with the another of the plurality of network terminals, if the determination unit determines that the another of the plurality of network terminals has the first IP address, andthe one of the plurality of network terminals includes;
a command receiver that receives the command from the administrator terminal over the network; and
a command transmitter that transmits the command received by the command receiver to the another of the plurality of network terminals.

Abstract
A network system is disclosed, including a plurality of network terminals connected to a network; and an administrator terminal that manages the network terminals across the network. One of the network terminals includes a command receiver that receives a command from the administrator terminal over the network, and a command transmitter that transits the command received by the command receiver to another of the plurality of network terminals. When the administrator terminal is allowed to communicate with only particular terminals, the network system allows the administrator terminal to transmit a command to terminals other than the particular terminals indirectly. Therefore, the network system enjoys enhanced advantages.

1. A network system comprising:
-
a plurality of network terminals connected to a network, each of the plurality of network terminals having an IP address different from one another; and an administrator terminal connected to the network to manage the plurality of network terminals; and a gateway, provided between the network and the administrator terminal, for restricting direct communication between the administrator terminal and the plurality of network terminals and allowing the administrator terminal to directly communicate with one of the plurality of network terminals, wherein the administrator terminal includes; a finding unit that causes the one of the plurality of network terminals to research information as to another of the plurality of network terminals that is capable of communicating directly with the one of the plurality of network terminals; a determination unit that determines based on the information whether the another of the plurality of network terminals has a first IP address that is allowed by the gateway to directly communicate with the administrator terminal; a transmission unit that transmits a command to the one of the plurality of network terminals, the command being for changing an IP address of the another of the plurality of network terminals to a different IP address that is allowed by the gateway to directly communicate with the administrator terminal, if the determination unit determines that the another of the plurality of network terminals does not have the first IP address; and a direct communication unit that establishes direct communication with the another of the plurality of network terminals, if the determination unit determines that the another of the plurality of network terminals has the first IP address, and the one of the plurality of network terminals includes; a command receiver that receives the command from the administrator terminal over the network; and a command transmitter that transmits the command received by the command receiver to the another of the plurality of network terminals. - View Dependent Claims (2, 3, 4, 5, 6)

7. A method for managing a plurality of network terminals connected to a network by an administrator terminal, each of the plurality of terminals having an IP address different from one another, the administrator terminal being connected through a gateway to the network, the gateway restricting direct communication between the administrator terminal and the plurality of network terminals and allowing the administrator terminal to directly communicate with one of the plurality of network terminals, comprising the steps of:
-
searching information as to another of the plurality of network terminals that is capable of communicating directly with the one of the plurality of network terminals; determining based on the information whether the another of the plurality of network terminals has a first IP address that is allowed by the gateway to directly communicate with the administrator terminal; and transmitting a command from the administrator terminal through the one of the plurality of network terminals to the another of the plurality of network terminals, the command being for changing an IP address of the another of the plurality of network terminals to a different IP address that allows the administrator terminal to directly communicate with the another of the plurality of network terminals, if it is determined that the another of the plurality of network terminals does not have the first IP address. - View Dependent Claims (8)

9. A storage medium storing a set of program instructions executable on a data processing device and usable for managing a plurality of network terminals connected to a network by an administrator terminal, each of the plurality of network terminals having an IP address different from one another, the administrator terminal being connected through a gateway to the network, the gateway restricting direct communication between the administrator terminal and the plurality of network terminals and allowing the administrator terminal to communicate directly with one of the plurality of network terminals, the instructions comprising:
-
instructions for searching information as to another of the plurality of network terminals that is capable of communicating directly with the one of the plurality of network terminals; instructions for determining based on the information whether the another of the plurality of network terminals has a first IP address that is capable of communicating directly with the administrator terminal; and instructions for transmitting a command from the administrator terminal through the one of the plurality of network terminals to the another of the plurality of network terminals, the command being for changing an IP address of the another of the plurality of network terminals to a different IP address that allows the administrator terminal to establish direct communication with the another of the plurality of network terminals, if it is determined that the another of the plurality of network terminals does not have the first IP address. - View Dependent Claims (10)
