Abstract

Methods, systems, and apparatuses for device routing management are disclosed. A client device of a wireless network may roam from a first access point to a second access point of the wireless network. The second access point, or the client device itself, may send a network message indicating the client device is currently being served by the second access point. The message may cause a network mapping stored at the first access point and/or at each device associated with the wireless network to be updated to indicate the client device is associated with the second access point, thereby enabling proper routing of network traffic to the client device via the second access point.

determine, via a second device of the plurality of devices, that the user device is no longer communicating with the first device, wherein the second device comprises an access point.

12. The one or more non-transitory computer-readable media of claim 8 , wherein the processor-executable instructions that cause the at least one processor to determine that the user device is no longer communicating with the first device further cause the at least one processor to determine, based on a time-to-live element of a network mapping table, that an amount of time indicated by the time-to-live element has elapsed, wherein the time-to-live element and the amount of time are associated with a voice call protocol.

13. The one or more non-transitory computer-readable media of claim 8 , wherein the processor-executable instructions that cause the at least one processor to determine that the portion of network traffic comprises voice call data further cause the at least one processor to:
