Abstract

A quality of service parameter associated with message traffic transmitted from a smart items infrastructure through a middleware message routing engine to one or more enterprise applications is monitored. In response to the monitored quality of service parameter, a number of parallel message processors that route messages from the plurality of smart items to the message routing engine is controlled.

Claims

1. A method comprising:

monitoring a quality of service parameter associated with message traffic transmitted from a smart items infrastructure comprising a plurality of smart items through a middleware message routing engine to one or more enterprise applications; and

controlling, in response to the monitored quality of service parameter, a number of parallel message processors that route messages from the plurality of smart items to the message routing engine.

2. The method of claim 1, wherein the message traffic is transmitted synchronously from the smart items infrastructure to the one or more enterprise applications.

3. The method of claim 1, wherein the quality of service parameter is a rate of message throughput between the smart items infrastructure and the one or more enterprise applications.

4. The method of claim 3,

wherein monitoring the rate of message throughput comprises comparing a current rate of message throughput to a previous rate of message throughput, and

wherein controlling the number of parallel message processors in response to the monitored rate of message throughput comprises activating an additional processor if the current rate is greater than the previous rate, and de-activating a processor if the current rate is less than the previous rate.

5. The method of claim 3,

wherein monitoring the rate of message throughput comprises comparing a current rate of message throughput to a previous rate of message throughput, and

wherein controlling the number of parallel message processors in response to the monitored rate of message throughput comprises:

determining that a current rate of message throughput is greater than a previous rate, and, in response to this determination, activating a processor;

and then, determining that a current rate of message throughput is less than a previous rate, and, in response to this determination, de-activating a processor;

and then, determining that a current rate of message throughput is greater than a previous rate, and, in response to this determination, de-activating a processor.

6. The method of claim 1, wherein the quality of service parameter is a rate of successful message transmission between the smart items infrastructure and the one or more enterprise applications.

7. The method of claim 1, further comprising aggregating payloads of a plurality of messages into a single message for transmission from the smart items infrastructure through the middleware message routing engine to the one or more enterprise applications.

8. A computer program product, tangibly embodied on computer-readable media, the computer program comprising computer-executable instructions for causing a data processing apparatus to:

monitor a quality of service parameter associated with message traffic transmitted from a smart items infrastructure comprising a plurality of smart items through a middleware message routing engine to one or more enterprise applications; and

control, in response to the monitored quality of service parameter, a number of parallel message processors that route messages from the plurality of smart items to the message routing engine.

9. The computer program product of claim 8, wherein the message traffic is transmitted synchronously from the smart items infrastructure to the one or more enterprise applications.

10. The computer program product of claim 8, wherein the quality of service parameter is a rate of message throughput between the smart items infrastructure and the one or more enterprise applications.

11. The computer program product of claim 10,

wherein controlling the number of parallel message processors in response to the monitored rate of message throughput comprises activating an additional processor if the current rate is greater than the previous rate, and de-activating a processor if the current rate is less than the previous rate.

12. The computer program product of claim 10,

wherein monitoring the rate of message throughput comprises comparing a current rate of message throughput to a previous rate of message throughput, and

wherein controlling the number of parallel message processors in response to the monitored rate of message throughput comprises:

determining that a current rate of message throughput is greater than a previous rate, and, in response to this determination, activating a processor;

and then, determining that a current rate of message throughput is less than a previous rate, and, in response to this determination, de-activating a processor;

and then, determining that a current rate of message throughput is greater than a previous rate, and, in response to this determination, de-activating a processor.

13. The computer program product of claim 8, wherein the quality of service parameter is a rate of successful message transmission between the smart items infrastructure and the one or more enterprise applications.

14. The computer program product of claim 8, further comprising computer-executable instructions for causing the data processing apparatus to aggregate payloads of a plurality of messages into a single message for transmission from the smart items infrastructure through the middleware message routing engine to the one or more enterprise applications.

15. A system comprising:
