Abstract

Provided is a network management method of a network manager. The network management method includes monitoring events including state information of a managed element wherein the events are published by the managed element included in a network, and generating commands for an action performed in the managed element according to the events, wherein the events are subscribed by the network manager managing the network.

Claims

1. A method for managing a network of an overlay network comprising:

selecting a service among network management services provided from a service provider according to a predetermined service QoS in response to a request of a network manager;

providing the selected service to the network manager; and

performing the service QoS and monitoring whether the provided service is matched with the serviced QoS or not.

2. The method of claim 1, wherein said selecting a service comprises:

selecting a composition service according to the service QoS; and

selecting a plurality of basic services included in the composition service according to the service QoS.

3. The method of claim 2, wherein said providing the selected service comprises:

requesting the plurality of selected basic services to the service provider; and

performing a composition service combined with the plurality of basic services provided from the service provider according to the request.

4. The method of claim 1, wherein in said selecting a service,

the service is selected additionally using context information about the service QoS.

5. The method of claim 1, wherein the network management service comprises at least one of:

a monitoring service for monitoring events published by a managed element included in a network and including state information of the managed element;

an analysis service for analyzing states of the managed element according to the events;

a flowchart service for generating a flowchart according to an operation performed in the managed element using the analyzing result; and

a command generation service for generating commands for operations performed in the managed element according to the flowchart.

6. The method of claim 1, wherein the network management service is provided to the overlay network by being published by a low-level network of the service provider.

7. A method for providing a service QoS of an overlay network, comprising:

configuring a service QoS including a service related QoS about services performed in an overlay network and a transport related QoS;

searching a service according to the service QoS using the service QoS;

performing the service related QoS and transmitting the transport related QoS to a service provider that provides the service; and

monitoring whether the providing of the searched service is matched with the service QoS.

8. The method of claim 7, wherein in said configuring a service QoS,

the service QoS is configured according to a request of a service requester that is provided with a service from the overlay network.

9. The method of claim 7, wherein in said searching a service,

the service is searched additionally using context information for the service QoS.

10. The method of claim 7, wherein the service provider is a low-level network of the overlay network.

11. The method of claim 7, wherein in said monitoring whether the providing of the searched service is matched with the service QoS,

the providing of the searched service is monitored whether the providing of the searched service is matched with a predetermined QoS policy when the providing of the searched service is not matched with the service QoS.

12. The method of claim 7, wherein the service comprises at least one of:

a monitoring service for monitoring events about state information of a managed element and published by the managed element;

an analysis service for analyzing states of the managed element according to the events;

a flowchart generation service for generating a flowchart according to operation performed in the managed element; and

a command generation service for generating commands of operations performed in the managed element according to the flowchart.
