Abstract

Techniques are provided for reducing the amount of event notifications within a Web Service Application (WSA) of a device such as a multi-functional peripheral (MFP). In one technique, a Subscription ID is linked with a Job ID within a reduced notification table. When an event occurs related to a specific job, an event notification is sent only to the subscriber associated with that job.

Claims

1. One or more non-transitory computer-readable media carrying instructions which, when executed by one or more processors, causes:

receiving, from one or more first client devices, at a network device, a plurality of subscription requests, wherein each subscription request is associated with a subscription for one or more events;

in response to receiving the plurality of subscription requests, storing subscription association data that associates, for each subscription request of the plurality of subscription requests, a client identifier and a subscription identifier, wherein the subscription association data is not associated with a job request;

after storing the subscription association data, receiving, from one or more second client devices, at the network device, a plurality of job requests;

after receiving a particular job request of the plurality of job requests, updating the subscription association data by associating a job identifier with a particular client identifier and a particular subscription identifier;

detecting, at the network device, a plurality of events;

determining that a particular event of the plurality of events is associated with a particular job; and

for the particular event, causing an event notification to be sent only to a particular client device that (a) is associated with a particular subscription of the particular event, wherein the particular subscription is associated with a subscription request of the plurality of subscription requests, and (b) sent a job request, of the plurality of job requests, that is associated with the particular job;

wherein a client device of the one or more first client devices that subscribed for the particular event does not receive a notification of the particular event.

2. The one or more non-transitory computer-readable media of claim 1, wherein the particular client device subscribed for the particular event.

3. The one or more non-transitory computer-readable media of claim 1, wherein:

a second client device that is different than the particular client device subscribed for the particular event; and

the particular client device is identified, at the network device, as a client device that is to be notified of the occurrence of the particular event.

4. The one or more non-transitory computer-readable media of Claim 1, wherein:

the subscription association data is stored prior to receiving the plurality of job requests;

the instructions, when executed by the one or more instructions, further cause, in response to receiving a second job request, of the plurality of job requests;

determining a particular client identifier associated with the second job request;

determining whether the second client identifier is indicated in the subscription association data;

if the second client identifier is indicated in the subscription association data, then storing a certain job identifier, associated with the second job request, in the subscription association data in association with the second client identifier.

5. The one or more non-transitory computer-readable media of claim 1, wherein:

causing an event notification to be sent comprises sending, from a first module executing on the network device, to a second module executing on the network device, a first subscription identifier associated with the particular subscription; and

the second module sends the event notification to the particular client device.

6. The one or more non-transitory computer-readable media of claim 5, wherein the first module performs the steps of determining and sending the subscription identifier.

7. One or more non-transitory computer-readable media carrying instructions which, when executed by one or more processors, cause:

storing subscription association data that associates, for each subscription request of a plurality of subscription requests, a client identifier and a subscription identifier that is unique relative to each other subscription identifier that is associated with another subscription request of the plurality of subscription requests, wherein none of the subscription identifiers is associated with a job request;

after storing the subscription association data, receiving, from one or more client devices, at a network device, a plurality of job requests;

for each job request of one or more of the plurality of job requests;

determining a particular client identifier associated with said each job request,

identifying the particular client identifier in the subscription association data,

generating, at the network device, a job identifier for said each job request, wherein the job identifier is unique relative to each other job identifier that is generated for another job request of the plurality of job requests, and

updating the subscription association data to associate the job identifier with a particular subscription identifier that is associated with the particular client identifier;

in response to detecting, at the network device, a first event that is associated with a first job request;

determining a first job identifier associated with the first job request, and

determining whether the first job identifier is indicated in the subscription association data, and

in response to determining that the first job identifier is indicated in the subscription association data, causing a particular notification to be sent to a particular client device that is associated with the client identifier that is associated with the first job identifier indicated in the subscription association data; and

in response to detecting, at the network device, a second event that is associated with a second job request that is different than the first job request;

determining a second job identifier associated with the second job request,

determining whether the second job identifier is indicated in the subscription association data, and

in response to determining that the second job identifier is not indicated in the subscription association data, determining to not cause a notification about the second event to be sent.

8. The one or more transitory computer-readable media of claim 7, wherein:

the subscription association data is stored in a table that comprises a plurality of columns;

the plurality of columns include a first column that stores subscription identifiers, a second column that stores client identifiers, and a third column that stores job identifiers after one or more of the plurality of job requests are received.

9. The one or more transitory computer-readable media of claim 8, wherein:

the plurality of columns include a fourth column that corresponds to an event sink includes second client identifiers;

at least one row of the table includes a first client identifier in the second column and a second client identifier in the fourth column; and

the second client identifier is different than the first client identifier.

10. The one or more non-transitory computer-readable media of claim 7, wherein:

the second event is of a particular type; and

the notification about the second event is not sent to a certain client device even though, at the time the second event was received, the certain client device subscribed for events of the particular type.

11. The one or more non-transitory computer-readable media of claim 7, wherein:

causing the particular notification to be sent to the particular client device comprises sending, from a first module, to a second module, a subscription identifier associated with first job identifier indicated in the subscription association data; and

the second module sends the particular notification to the particular client device.

12. The one or more non-transitory computer-readable media of claim 11, wherein the first module performs the steps of associating, determining whether the first job identifier is indicated in the subscription association data, and sending the subscription identifier to the second module.

13. One or more non-transitory computer-readable media carrying instructions which, when executed by one or more processors, cause:

receiving, from a plurality of client devices, at a scan device, a plurality of event subscription requests, wherein each event subscription request is for receiving a notification of one or more events that are generated by the scan device;

in response to receiving the plurality of event subscription requests, storing, at the scan device, a plurality of associations for the plurality of event subscription requests, wherein each association of the plurality of associations associates a scan destination identifier with a subscription identifier;

after storing the plurality of associations, receiving, at the scan device, a scan event that is associated with a particular scan destination identifier;

in response to receiving the scan event, determining whether the particular scan destination identifier is indicated in the plurality of associations;

only if the particular scan destination identifier is indicated in the plurality of associations, then;

identifying, in an association, of the plurality of associations, that includes the particular scan destination identifier, a particular subscription identifier that is associated with the particular scan destination identifier, and

causing a notification of the scan event to be sent to a client device that is associated with the particular subscription identifier;

wherein one or more client devices that have subscribed for the scan event do not receive a notification of the scan event.

14. The one or more non-transitory computer-readable media of claim 13, wherein:

each association in the plurality of associations corresponds to a different subscription of the plurality of event subscription requests; and

the plurality of associations are stored in response to receiving the plurality of-event subscription requests.

15. The one or more non-transitory computer-readable media of claim 13, wherein the scan event is generated in response to a user that selects a scan destination that corresponds to the particular scan destination identifier, loads a printed document onto a scanning interface of the scan device, and provides input that causes the scan device to scan the printed document.

16. The one or more non-transitory computer-readable media of claim 13, wherein the scan destination identifier is a scan destination display name.
