Abstract

In a hierarchical network managing system, an upper layer manager manages at least one upper layer agent. An upper layer user interface is provided for the upper layer manager and can communicate with the upper layer manager. A lower layer manager manages at least one lower layer agent. A lower layer user interface is provided for the lower layer manager and can communicate with the lower layer manager and the upper layer user interface.

Claims

1. A hierarchical network managing system comprising:

at least one upper layer agent;

an upper layer manager for managing said at least one upper layer agent;

an upper layer user interface which is provided for said upper layer manager and which can communicate with said upper layer manager;

at least one lower layer agent;

a lower layer manager for managing said at least one lower layer agent; and

a lower layer user interface provided for said lower layer manager and which can communicate with said lower layer manager and said upper layer user interface.

2. A hierarchical network managing system according to claim 1, wherein said upper layer user interface and said lower layer user interface form an integrated user interface module.

3. A hierarchical network managing system according to claim 1, wherein said upper layer user interface and said lower layer user interface are provided as an upper layer user interface module and a lower layer user interface module which are separated from each other.

4. A hierarchical network managing system according to claim 1, wherein said upper layer user interface communicates with said lower layer user interface when a request inputted from a user through said upper layer user interface requires processing by said lower layer agent.

5. A hierarchical network managing system according to claim 4, wherein said upper layer user interface issues a first processing request for first processing to said upper layer agent, and said upper layer agent performs said first processing in response to said first request while said upper layer agent communicates with said lower layer agent through said lower layer manager, if necessary.

6. A hierarchical network managing system according to claim 5, wherein said upper layer user interface issues a second processing request to said lower layer user interface, when said first processing is ended, and said lower layer user interface issues a second request for the second processing to said lower layer agent through said lower layer manager when the second request is inputted from the user through said lower layer user interface.

7. A hierarchical network managing system according to claim 6, wherein said lower layer user interface issues an end notice to said upper layer user interface when said second processing is ended in said lower layer agent, and said upper layer user interface ends the processing for the request inputted from the user.

8. A network managing system, said network managing system comprising a plurality of layers, each of said plurality of layers having:

a plurality of managers;

a plurality of agents connected to said plurality of managers; and

a plurality of user interfaces, each of which is provided for one of said plurality of managers independently from the others of said plurality of managers.

9. A network managing system according to claim 8, wherein said user interfaces for said plurality of layers form an integrated user interface module.

10. A network managing system according to claim 9, wherein said user interfaces for said plurality of layers communicate with each other.

11. A network managing system according to claim 8, wherein one of said plurality of user interfaces for one of said layers is independent of the others of said user interfaces corresponding to the others of said layers.

12. A network managing system according to claim 11, wherein said user interfaces for said plurality of layers communicate with each other.

13. A method of managing a plurality of layers in a hierarchical network managing system, comprising the steps of:

inputting a request from a user through an upper layer user interface;

issuing a first processing request for first processing from an upper layer user interface to an upper layer agent through an upper layer manager when the request is inputted from the user; and

issuing a second processing request from said upper layer user interface to a lower layer user interface, when said first processing is ended.

14. A method according to claim 13, further comprising the step of:

performing said first processing in response to said first request by said upper layer agent while said upper layer agent communicates with a lower layer agent through a lower layer manager, if necessary.

15. A method according to claim 14, further comprising the steps of:

prompting the user to input a second processing request for second processing; and

issuing the second request from said lower layer user interface to said lower layer agent through a lower layer manager in response to the input from the user.

16. A method according to claim 15, further comprising the step of:

issuing an end notice from said lower layer user interface to said upper layer user interface when said second processing is ended in said lower layer agent; and

ending the processing for the request inputted from the user in said upper layer user interface.
