Scalable and flexible internet fax architecture for processing outbound fax messages
First Claim
1. A method of delivering fax messages, the method comprising:
- receiving, at an initial submission gateway device of an Internet fax system, a request to deliver a fax message to one or more third parties;
causing to be stored, by the initial submission gateway device, one or more source files associated with the request and representing at least a portion of content to be included as part of the fax message to a shared storage area of the Internet fax system accessible by a plurality of imaging systems and a plurality of fax processing resources of the Internet fax system;
for each imaging system of the plurality of imaging systems, calculating a load score based on one or more of a processor load associated with the imaging system and a memory load associated with the imaging system;
selecting an imaging system of the plurality of imaging systems to convert the one or more source files into a digital representation suitable for faxing based on their respective load scores; and
converting, by the selected imaging system, the one or more source files into the digital representation, associating the digital representation with an outbound fax job and causing the fax message to be delivered to the one or more third parties by submitting the outbound fax job to a fax modem of the plurality of fax processing resources.

Abstract
Methods and systems for processing outbound fax messages in an efficient and scalable manner are provided. According to one embodiment, a request to deliver a fax message is received by an Internet fax system. Source files associated with the request and representing at least a portion of content to be included as part of the fax message are stored to a shared storage area accessible by multiple imaging systems and multiple fax processing resources. A load score is calculated for each imaging system based on one or more of a processor load and a memory load. An imaging system is selected, based on the load scores, to convert the source files into a digital representation suitable for faxing. The source files are converted by associating the digital representation with an outbound fax job. The fax message is delivered by submitting the outbound fax job to one of the fax modems.

9. A method of delivering fax messages, the method comprising:
-
for each of a plurality of imaging systems of an Internet fax system, calculating a load score based on one or more of a processor load associated with the imaging system and a memory load associated with the imaging system; and responsive to receiving, at an initial submission gateway device of a plurality of initial submission gateway devices, a request to deliver a fax message to one or more third parties, selecting, by the initial submission gateway device, an imaging system of the plurality of imaging systems based on their respective load scores, to convert one or more source files associated with the request and representing at least a portion of content to be included as part of the fax message into a digital representation suitable for faxing; and causing the fax message to be delivered to the one or more third parties by associating the digital representation with an outbound fax job and submitting the outbound fax job to a fax modem of a plurality of fax processing resources of the Internet fax system. - View Dependent Claims (10, 11, 12, 13)

14. A method of delivering fax messages, the method comprising:
-
for each imaging system of a plurality of imaging systems of an Internet fax system, calculating a load score based on one or more of a processor load associated with the imaging system and a memory load associated with the imaging system; responsive to receiving fax requests to deliver fax messages, at one or more initial submission gateway devices from a plurality of subscribers of the Internet fax system, generating, by the one or more initial submission gateway devices, work requests corresponding to the fax requests, the work requests each containing information identifying a selected imaging system of the plurality of imaging systems to convert one or more source files associated with the fax requests into digital representations suitable for faxing, wherein the selected imaging system is selected from among the plurality of imaging systems based on their respective load scores; ensuring equal access by the plurality of subscribers to a plurality of simultaneous job slots provided within each of the plurality of imaging systems, by favoring for assignment to an available job slot of the plurality of simultaneous job slots those of the work requests, by a particular imaging system of the plurality of imaging systems, that are associated with a subscriber other than one for which the particular imaging system is currently processing; and after completing processing of work requests by the particular imaging system, associating the digital representations with outbound fax jobs and causing the fax messages to be delivered by submitting the outbound fax jobs to one or more fax modems of a plurality of fax processing resources of the Internet fax system. - View Dependent Claims (15, 16, 17)
