Abstract

Methods, computer systems, and computer program products for improving resiliency in a network of computing components functioning according to a multilayered Open Systems Interconnection (OSI) model include, upon exceeding a predetermined threshold for at least one of the multiple layers in the OSI model, for a certain event, a real-time notification of the event is provided in an inter-layer basis such that the responsible entity manages the event according to an OSI model-wide system.

Claims

1. A method for improving resiliency in a network of computing components functioning according to a multilayered Open Systems Interconnection (OSI) model by a processor device, comprising:

upon exceeding a predetermined threshold for at least one of the multiple layers for a certain event, providing a real-time notification of the event in an inter-layer basis such that the responsible entity manages the event according to an OSI model-wide system.

2. The method of claim 1, wherein managing the event further includes notifying all layer 2 or layer 3 devices on the network of the event, the layer 2 or layer 3 devices which support event notification rebroadcasting the notification.

3. The method of claim 2, wherein rebroadcasting the notification by layer 2 or layer 3 devices further includes rebroadcasting the notification through all ports of the layer 2 or layer 3 device, except the port from which the notification was received, such as to flood the network to ensure dissemination of the notification.

4. The method of claim 3, wherein devices that do not support event notification harmlessly disregard the notification frame.

5. The method of claim 2, wherein notifying further comprises creating, by the layer 2 or layer 3 device, a set of packets and frames containing the layer'"'"'s threshold event information describing the event that occurred.

6. The method of claim 1, wherein exceeding a predetermined threshold further includes setting user-defined key area thresholds for each layer in the OSI model.

7. The method of claim 1, wherein the certain event is a failure event in a communications link between one or more layers.

8. The method of claim 1, wherein the notification is performed by a firmware update to computing components.

9. A system for improving resiliency in a network of computing components functioning according to a multilayered Open Systems Interconnection (OSI) model, comprising:

at least one processor device, operable within the OSI model environment, wherein the at least one processor device;

upon exceeding a predetermined threshold for at least one of the multiple layers for a certain event, provides a real-time notification of the event in an inter-layer basis such that the responsible entity manages the event according to an OSI model-wide system.

10. The system of claim 9, wherein the at least one processor device manages the event, managing the event further including notifying all layer 2 or layer 3 devices on the network of the event, the layer 2 or layer 3 devices which support event notification rebroadcasting the notification.

11. The system of claim 10, wherein the at least one processor device rebroadcasts the notification, wherein rebroadcasting the notification by layer 2 or layer 3 devices further includes rebroadcasting the notification through all ports of the layer 2 or layer 3 device, except the port from which the notification was received, such as to flood the network to ensure dissemination of the notification.

12. The system of claim 11, wherein devices that do not support event notification harmlessly disregard the notification frame.

13. The system of claim 10, wherein the at least one processor device notifies, the notifying further comprising creating, by the layer 2 or layer 3 device, a set of packets and frames containing the layer'"'"'s threshold event information describing the event that occurred.

14. The system of claim 9, wherein exceeding a predetermined threshold further includes setting user-defined key area thresholds for each layer in the OSI model.

15. The system of claim 9, wherein the certain event is a failure event in a communications link between one or more layers.

16. The system of claim 10, wherein the notification is performed by a firmware update to computing components.

17. A computer program product for improving resiliency in a network of computing components functioning according to a multilayered Open Systems Interconnection (OSI) model by at least one processor device operable within the OSI model, the computer program product comprising a non-transitory computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

a first executable portion that, upon exceeding a predetermined threshold for at least one of the multiple layers for a certain event, provides a real-time notification of the event in an inter-layer basis such that the responsible entity manages the event according to an OSI model-wide system.

18. The computer program product of claim 17, further comprising a second executable portion that manages the event, wherein managing the event further includes notifying all layer 2 or layer 3 devices on the network of the event, the layer 2 or layer 3 devices which support event notification rebroadcasting the notification.

19. The computer program product of claim 18, further comprising a third executable portion that rebroadcasts the notification, wherein rebroadcasting the notification by layer 2 or layer 3 devices further includes rebroadcasting the notification through all ports of the layer 2 or layer 3 device, except the port from which the notification was received, such as to flood the network to ensure dissemination of the notification.

20. The computer program product of claim 19, wherein devices that do not support event notification harmlessly disregard the notification frame.

21. The computer program product of claim 18, further comprising a third executable portion that notifies, wherein notifying further comprises creating, by the layer 2 or layer 3 device, a set of packets and frames containing the layer'"'"'s threshold event information describing the event that occurred.

22. The computer program product of claim 17, wherein exceeding a predetermined threshold further includes setting user-defined key area thresholds for each layer in the OSI model.

23. The computer program product of claim 17, wherein the certain event is a failure event in a communications link between one or more layers.

24. The computer program product of claim 18, wherein the notification is performed by a firmware update to computing components.
