Abstract

Method and apparatus for processing system management messages are described herein. In one embodiment, a throttling policy associated with a network node is determined for throttling system management messages to be sent to a system management server over a network. The system management messages are then sent to the system management server according to the throttling policy, where the system management server is configured to manage multiple network nodes over the network. Other methods and apparatuses are also described.

Claims

1. A computer-implemented method for processing system management messages, the method comprising:

determining a throttling policy associated with a network node for throttling system management messages to be sent to a system management server over a network, the throttling policy including

a queue throttling policy defining a first maximum number of system management messages that can be dequeued from a message queue within a burst period, and

a send throttling policy defining a second maximum number of the dequeued system management messages that can be sent to the system management server before entering a quiet period during which no system management messages are sent; and

throttling the system management messages sent to the system management server according to the queue throttling policy and the send throttling policy independently and concurrently.

2. The method of claim 1, wherein determining the throttling policy comprises:

determining a duration of the quiet period.

3. The method of claim 2, further comprising entering the quiet period after sending up to the second maximum number of system management messages to the system management server.

4. The method of claim 3, further comprising resuming sending further system management messages to the system management server up to the second maximum number of system management messages after the quiet period lapses.

5. The method of claim 1, wherein determining the throttling policy comprises:

determining a duration of the burst period.

6. The method of claim 5, further comprising:

for each burst period, dequeuing up to the first maximum number of system management messages from the message queue; and

transmitting the dequeued system management messages to the system management server over the network.

7. The method of claim 6, wherein the dequeuing is suspended once up to the first maximum number of system management messages have been dequeued from the message queue until a current burst period lapses.

8. The method of claim 1, further comprising:

in response to an instruction received from the system management server indicating one of disabling, enabling, and modifying the throttling policy, updating the throttling policy; and

throttling further system management messages according to the updated throttling policy.

9. The method of claim 1, further comprising:

identifying a particular system management message that satisfies a predetermined condition; and

transmitting the identified system management message to the system management server without throttling.

10. The method of claim 1, further comprising:

dequeuing by dequeuing logic system management messages from the message queue according to the queue throttling policy; and

independently and concurrently sending by sending logic the dequeued system management messages according to the send throttling policy, wherein a system management message is dequeued from the message queue and sent to the system management server only when the dequeuing logic is within a burst period and the sending logic has not entered a quiet period at the point in time.

11. A computer-readable storage medium having instructions, which when executed by a processor, cause the processor to perform a method for processing system management messages, the method comprising:

determining a throttling policy associated with a network node for throttling system management messages to be sent to a system management server over a network, the throttling policy including

a queue throttling policy defining a first maximum number of system management messages that can be dequeued from a message queue within a burst period, and

a send throttling policy defining a second maximum number of the dequeued system management messages that can be sent to the system management server before entering a quiet period during which no system management messages are sent; and

throttling the system management messages sent to the system management server according to the queue throttling policy and the send throttling policy independently and concurrently.

12. The computer-readable storage medium of claim 11, wherein determining the throttling policy comprises:

determining a duration of the quiet period.

13. The computer-readable storage medium of claim 12, wherein the method further comprises entering the quiet period after sending up to the second maximum number of system management messages to the system management server.

14. The computer-readable storage medium of claim 13, wherein the method further comprises resuming sending further system management messages to the system management server up to the second maximum number of system management messages after the quiet period lapses.

15. The computer-readable storage medium of claim 11, wherein determining the throttling policy comprises:

determining a duration of the burst period.

16. The computer-readable storage medium of claim 15, wherein the method further comprises:

for each burst period, dequeuing up to the first maximum number of system management messages from the message queue; and

transmitting the dequeued system management messages to the system management server over the network.

17. The computer-readable storage medium of claim 16, wherein the dequeuing is suspended once up to the first maximum number of system management messages have been dequeued from the message queue until a current burst period lapses.

18. The computer-readable storage medium of claim 11, wherein the method further comprises:

in response to an instruction received from the system management server indicating one of disabling, enabling, and modifying the throttling policy, updating the throttling policy; and

throttling further system management messages according to the updated throttling policy.

19. The computer-readable storage medium of claim 11, wherein the method further comprises:

identifying a particular system management message that satisfies a predetermined condition; and

transmitting the identified system management message to the system management server without throttling.

20. The computer-readable storage medium of claim 11, wherein the method further comprises:

dequeuing by dequeuing logic system management messages from the message queue according to the queue throttling policy; and

independently and concurrently sending by sending logic the dequeued system management messages according to the send throttling policy, wherein a system management message is dequeued from the message queue and sent to the system management server only when the dequeuing logic is within a burst period and the sending logic has not entered a quiet period at the point in time.

21. A network node, comprising:

a throttling policy unit to determine a throttling policy associated with the network node for throttling system management messages to be sent to a system management server over a network, the throttling policy including

a queue throttling policy defining a first maximum number of system management messages that can be dequeued from a message queue within a burst period, and

a send throttling policy defining a second maximum number of the dequeued system management messages that can be sent to the system management server before entering a quiet period during which no system management messages are sent; and

a message processing unit coupled to the throttling policy unit to throttle the system management messages sent to the system management server according to the queue throttling policy and the send throttling policy independently and concurrently.

22. The network node of claim 21, further comprising a message queue coupled to the message processing unit to buffer the system management messages, wherein the message processing unit is configured to dequeue the system management messages from the message queue and to send the dequeued system management messages to the system management server.
