Queue processor for document servers

1. A computer program product comprising a non-transitory computer-readable medium storing a set of computer-executable instructions executable to process documents received at a facsimile server in an environment that comprises the facsimile server, a plurality of document transport modules, and a queue processor, the set of computer-executable instructions comprising instructions for:

implementing a document queue for maintaining a plurality of pending documents received by the facsimile server;

placing the documents received at the facsimile server in the document queue;

evaluating the number and type of pending documents in the document queue;

evaluating system resources of the facsimile server;

implementing a plurality of document flows, each document flow comprising a component configurable to process documents received at the facsimile server;

configuring, by the queue processor, each document flow of the plurality of document flows to handle a particular type of document;

determining whether there is an efficient allocation of implemented document flows based on the evaluation of the number and type of pending documents in the document queue and the evaluation of system resources of the facsimile server;

allocating, by the queue processor, the plurality of document flows based on a resource utilization of the facsimile server and based on the evaluated number and types of pending documents in the document queue to create a set of allocated document flows, the allocating of the plurality of document flows including increasing or decreasing, by the queue processor, a number of document flows that manage processing of documents from the document queue, each document flow in the set of allocated document flows associated with at least one document transport module from the plurality of document transport modules;

retrieving a first document of a first type from the document queue using a first document flow from the set of allocated document flows, the first document flow configured to handle the first document type;

providing the first document to a first document transport module associated with the first document flow; and

signaling the first document transport module to send the first document, wherein the first document transport module is responsive to the signal to apply rules to route the first document to a first target selected from a plurality of targets, the plurality of targets including a plurality of transports.

2. The computer program product of claim 1 , wherein the set of computer-executable instructions comprises instructions for assigning the first document from the document queue to the first document flow from the set of allocated document flows based on a document property of the first document.

3. The computer program product of claim 2 , wherein the set of computer-executable instructions comprises instructions for assigning the first document to the first document flow based on the first document type of the first document.

4. The computer program product of claim 2 , wherein the first document has associated metadata and wherein the set of computer-executable instructions comprises instructions for assigning the first document to the first document flow based on the associated metadata.

5. The computer program product of claim 1 , wherein the set of computer-executable instructions comprises instructions for providing a configuration for the first document flow, the configuration of the first document flow including an indication of a document property.

6. The computer program product of claim 5 , wherein the document property comprises the first document type of the first document.

7. The computer program product of claim 5 , wherein the first document has associated metadata and the document property comprises the associated metadata.

8. The computer program product of claim 1 , wherein the documents received by the facsimile server, including the first document, are facsimile documents.

9. The computer program product of claim 1 , wherein the plurality of transports comprises a facsimile transport.

10. The computer program product of claim 9 , wherein the plurality of targets includes a second document transport module.

11. The computer program product of claim 1 , wherein the set of computer-executable instructions comprises instructions for changing a number of allocated document flows in the set of allocated document flows based on the resource utilization of the facsimile server.

12. The computer program product of claim 1 , wherein the set of computer-executable instructions comprises instructions for configuring the first document flow to handle documents having a first property and dynamically reconfiguring the first document flow to handle documents having a second property.

13. A method comprising:

in an environment that comprises a facsimile server, a plurality of document transport modules, and a queue processor:

implementing a document queue for maintaining a plurality of pending documents received by the facsimile server;

placing documents received at the facsimile server in the document queue;

evaluating the number and type of pending documents in the document queue;

evaluating system resources of the facsimile server;

implementing a plurality of document flows, each document flow comprising a component configurable to process documents received at the facsimile server;

configuring, by the queue processor, each document flow of the plurality of document flows to handle a particular type of document;

determining whether there is an efficient allocation of implemented document flows based on the evaluation of the number and type of pending documents in the document queue and the evaluation of system resources of the facsimile server;

allocating, by the queue processor, the plurality of document flows based on a resource utilization of the facsimile server and based on the evaluated number and types of pending documents in the document queue to create a set of allocated document flows, the allocating of the plurality of document flows including increasing or decreasing, by the queue processor, a number of document flows that manage processing of documents from the document queue, each document flow in the set of allocated document flows associated with at least one document transport module from the plurality of document transport modules;

retrieving a first document of a first type from the document queue using a first document flow from the set of allocated document flows, the first document flow configured to handle the first document type;

providing the first document to a first document transport module associated with the first document flow; and

signaling the first document transport module to send the first document, wherein the first document transport module is responsive to the signal to apply rules to route the first document to a first target selected from a plurality of targets, the plurality of targets including a plurality of transports.

14. The method of claim 13 , further comprising assigning the first document from the document queue to the first document flow from the set of allocated document flows based on a document property of the first document.

15. The method of claim 14 , wherein the first document is assigned to the first document flow based on the first document type of the first document.

16. The method of claim 14 , wherein the first document has associated metadata and is assigned to the first document flow based on the associated metadata.

17. The method of claim 13 , wherein the first document flow is configured to retrieve the first document from the document queue based on the first document type of the first document.

18. The method of claim 13 , wherein the first document has associated metadata and the first document flow is configured to retrieve the first document from the document queue based on the associated metadata.

19. The method of claim 13 , wherein the documents received by the facsimile server, including the first document, are facsimile documents.

20. The method of claim 13 , wherein the plurality of transports comprises a facsimile transport.

21. The method of claim 20 , wherein the plurality of targets includes a second document transport module.

22. The method of claim 13 , further comprising changing a number of allocated document flows in the set of allocated document flows based on the resource utilization of the facsimile server.

23. The method of claim 13 , further comprising dynamically reconfiguring the first document flow from handling documents having a first property to handle documents having a second property.
