Abstract

A method for processing an event between a controller and a network device is disclosed. A method for processing an event in a network device comprises the steps of: receiving an event notification registration request from a controller; monitoring the occurrence of an event corresponding to the event notification registration request and; when an event occurs, notifying the event occurrence to the controller. Thus, the controller can reduce the load through reducing the number of times of message transmissions for monitoring the event by a switch.

First claim

1 . A method for processing an event, performed by a network apparatus, the method comprising:
receiving an event notification registration request from a controller; monitoring an occurrence of an event corresponding to the event notification registration request; and when the event occurs, notifying the occurrence of the event to the controller.

2 . The method according to claim 1 , wherein the event notification registration request includes a threshold value.

3 . The method according to claim 2 , wherein, in the notifying the occurrence of the event to the controller, the occurrence of the event is notified when the threshold value is achieved.

4 . The method according to claim 1 , wherein, in the receiving the event notification registration request, the event notification registration request specifies an event on a flow or a port.

5 . The method according to claim 4 , wherein, in the notifying the occurrence of the event to the controller, the occurrence of the event is notified when a usage amount of the flow exceeds a threshold value.

6 . The method according to claim 4 , wherein, in the notifying the occurrence of the event to the controller, the occurrence of the event is notified when a packet drop occurs in the port.

7 . The method according to claim 1 , wherein, in the receiving the event notification registration request, the event notification registration request includes identification information of the controller, information on an event to be monitored, and information on a notification cycle.

8 . The method according to claim 7 , wherein, in the notifying the occurrence of the event to the controller, the occurrence of the event is notified to the controller according to the notification cycle.

9 . A method for monitoring an event, performed by a controller, the method comprising:
requesting at least one network apparatus to register an event to be notified; receiving a result of the registration of the event to be notified according to the requesting from the at least one network apparatus; and controlling an event notification manner for the event registered in the at least one network apparatus.

10 . The method according to claim 9 , further comprising being notified of occurrence of the event by the at least one network apparatus, according to the controlled event notification manner.

11 . The method according to claim 9 , wherein the event notification registration request includes a threshold value, and an occurrence of the event is notified by the at least one network apparatus when the threshold value is achieved.

12 . The method according to claim 11 , wherein the occurrence of the event is notified when a usage amount of a flow exceeds the threshold value.

13 . The method according to claim 9 , wherein, in the controlling the event notification manner, the controller controls the at least one network apparatus to perform at least one of pause, resumption, and deletion of the event registered in the at least one network apparatus.

14 . A computer-readable recording medium storing a program for executing a method for monitoring an event by a processor, the method comprising:
generating an event notification registration request command for requesting a network apparatus to notify an occurrence of an event; generating a command for controlling an event notification manner of the network apparatus; and being notified of the occurrence of the event by the network apparatus based on the event notification registration request command and the command for controlling the event notification manner.

15 . The computer-readable recording medium according to claim 14 , wherein the method further comprises transmitting the event notification registration request command and the command for controlling the event notification manner to the network apparatus.

16 . The computer-readable recording medium according to claim 14 , wherein the event notification registration request includes a threshold value, and the occurrence of the event is notified to the controller by the network apparatus when the threshold value is achieved.

17 . The computer-readable recording medium according to claim 14 , wherein the command for controlling the event notification manner includes at least one of pause, resumption, and deletion of notification of the event.
