Abstract

Disclosed is a system for dynamically updating remote service objects to manage a network device having various characteristics by Java RMI (Remote Method Invocation), and a method thereof. The system includes a network device manager for authenticating a transmission message communicated between a network device and a management device and transferring and initializing objects for management of the network device, and a management agent. The management method includes a remote object transmission step, a remote object authentication step, a remote object installation step, and a network device management step.

Claims

1. A network device management method, which is for a network device management system, the network device management method comprising:

(a) a network device requesting a management device to transmit a management device implementation object, and receiving the requested management device implementation object;

(b) the network device authenticating and decoding the received management device implementation object;

(c) a management agent of the network device storing and registering the management device implementation object; and

(d) the management device calling an implementation object of the network device through an interface object, and outputting a corresponding result value.

3. The network device management method as claimed in claim 1, comprising:

storing the received management device implementation object in a remote method invocation (RMI) registry by the management agent.

4. The network device management method as claimed in claim 1, further comprising:

returning the result value of the implementation object called by the network manager to the network manager.

2. A network device management method, which is for a network device management system, the network device management method comprising:

(a) a management device requesting a network device to transmit a network device interface object, and receiving the network device interface object;

(b) the management device authenticating and decoding the received network device interface object;

(c) a network device manager of the management device storing and registering the network device interface object; and

(d) the network device manager calling an implementation object of the network device through the interface object, and outputting a corresponding result value.

5. The network device management method as claimed in claim 2, further comprising:

returning the result value of the implementation object called by the network manager to the network manager.

6. A network device, which dynamically updates a service object for network management of a management device, the network device comprising:

a management agent for requesting a network device manager of the management device to transmit a management device implementation object, receiving an encoded implementation object, and authenticating and decoding the received implementation object.

7. The network device as claimed in claim 6, wherein the management agent comprises:

a network device initialization processor for requesting the management device to transmit the management device implementation object, receiving the implementation object, authenticating and decoding the received implementation object with a given public key and a received message authentication code, and registering the implementation object on a RMI registry;

a network device implementation object for providing device information based on inherent functions and hardware characteristics of the network device; and

a management device implementation object for providing a management service capable of being managed using an application program interface (API) provided in Java.

8. A management device, which is for dynamically updating a service object to control and manage a network device, the management device comprising:

a network device manager for requesting a remote management agent to transmit a network device interface object, receiving the encoded object, authenticating and decoding the received object, and installing the authenticated and decoded object in the management device.

9. The management device as claimed in claim 8, wherein the network device manager comprises:

a network device registration processor for requesting the network device to transmit a network device interface object, receiving the requested interface object, authenticating and decoding the received interface object with a given public key and a received message authentication code, and reporting the addition of a new management service;

a network device interface object for providing device information based on inherent functions and hardware characteristics of the management device; and

a management device interface object for providing a management service capable of being managed using an API supported by Java.
