System, method, and computer program for maintaining quality of experience for a client device on a network

摘要

A system, method, and computer program product are provided for maintaining quality of experience (QoE) for a client device on a network. In use, access points that are available to a client device are determined, based on a policy. Additionally, a current QoE provided to the client device by one of the access points utilized by the client device to access the network is determined. This QoE could be valued as a score computed by a function called QoE Metric taking QoS parameters as inputs. An expected QoE associated with each of the other access points is then determined. Further, the access point utilized by the client device to access the network is conditionally switched to one of the other access points, based on the current QoE and the expected QoEs. Additionally, any potential QoE downgrades on the current access point is detected using QoE Degradation Patterns that could be matched with current QoS measures and can encourage the client device to determine more accurately the current QoE.

1. A computer program embodied on a non-transitory computer readable medium, comprising computer code for:
determining access points that are available to a client device, based on a policy; determining whether one or more quality of experience (QoE) degradation patterns are present at the client device, including:
checking a status of a link layer of the client device to determine a plurality of applications running on the client device, andapplying a configuration file containing a plurality of the QoE degradation patterns to the determined plurality of applications to determine whether one or more of the plurality of the QoE degradation patterns are present; and upon determining that one or more quality of experience (QoE) degradation patterns are present at the client device:
determining a current QoE provided to the client device by one of the access points utilized by the client device to access a network;determining an expected QoE associated with each of the other access points; andconditionally switching the access point utilized by the client device to access the network to one of the other access points, based on the current QoE and the expected QoEs.
