Distributed event delivery
View Patent ↗A distributed method of delivering events to agent devices. A first software module generates an event, e.g., a screen pop event or a ringing event, for delivery to a second module responsible for an agent device. A third module, which may be the same module as the first module, evaluates a hash function to determine an identifier for the second module from an identifier for the agent device. The first module delivers the event to the second module, which responds to the event, e.g., by causing an agent device to generate a ringing alert or to display a screen pop.
1. A method for distributed event delivery, comprising:
generating, by a first module executing on a first computing device, an event for a contact center resource device,
identifying, by the first module, a resource identifier (ID) for the contact center resource device;
identifying, by the first module, a second module responsible for the contact center resource device, wherein the identifying comprises:
providing the resource ID to a function called by the first module;
receiving as an output, from the function, a module identifier (ID) for the second module; and
sending, by the first module, the event to the second module based on the identified module ID for forwarding the event to the contact center resource device.
2. The method of claim 1 further comprising:
forwarding the event to a resource identified by the resource ID, wherein the resource generates an output in response to the event.
3. The method of claim 2 , wherein the event is a ringing event.
4. The method of claim 3 , comprising:
receiving, by the resource, the ringing event; and
generating, by the resource, a ringing alert.
5. The method of claim 2 , comprising routing a call to an agent device associated with the resource ID.
6. The method of claim 2 , wherein the event is a screen pop event.
7. The method of claim 6 , comprising:
receiving, by the resource, the screen pop event; and
generating, by the resource, a screen pop.
8. The method of claim 1 , wherein the function is a hash function.
9. The method of claim 8 , wherein the hash function is a consistent hash function.
10. The method of claim 9 , wherein the hash function comprises:
a first basic hash function configured to map resource identifiers into a range; and
a second basic hash function configured to map module identifiers into the range.
11. The method of claim 10 , wherein the second basic hash function is further configured to map a replica of each module identifier into the range.
12. The method of claim 8 , wherein the hash function is configured to map resource identifiers corresponding to resources in a geographic region into module identifiers corresponding to modules executing on computing devices in the geographic region.
13. The method of claim 1 , wherein the second module executes on a second computing device.
14. The method of claim 13 , wherein the second computing device is the same computing device as the first computing device.
15. A system for distributed event delivery, the system comprising:
a first computing device; and
a first memory hosting a first module,
wherein the first memory has stored thereon instructions that, when executed by the first computing device, cause the first computing device to:
generate an event for a contact center resource device;
identify a resource identifier (ID) for the contact center resource device;
identify a second module responsible for the contact center resource device, the second module being configured to execute on a second computing device, wherein the instructions further include instructions that cause the first computing device to:
provide the resource ID to a function called by the first module;
receive as an output, from the function, a module identifier (ID) for the second module; and
send the event to the second module based on the identified module ID for forwarding the event to the contact center resource device.
16. The system of claim 15 , wherein the function is a hash function.
17. The system of claim 16 , wherein the hash function is a consistent hash function.
18. The system of claim 17 , wherein the hash function comprises:
a first basic hash function configured to map resource identifiers into a range; and
a second basic hash function configured to map module identifiers into the range.
19. The system of claim 18 , wherein the second basic hash function is further configured to map a replica of each module identifier into the range.
20. The system of claim 15 , wherein the second computing device is the same computing device as the first computing device.
