DEEP PACKET INSPECTION (DPI) AWARE CLIENT STEERING AND LOAD BALANCING IN WIRELESS LOCAL AREA NETWORK (WLAN) INFRASTRUCTURE

摘要

Methods and systems are described for intelligently steering client devices operating in an enterprise network system to an appropriate access point based on types of traffic on each client device and/or types of traffic on access points. In particular, client devices may be moved to a different access point when the wireless channel provided by a current access point fails to meet the signal strength requirements of latency sensitive traffic utilized by the client device. Client devices may be further steered to new access points based on load conditions on access points. For example, client devices with low priority traffic sessions may be steered away from access points with high traffic load levels. Accordingly, the methods and systems described herein ensure improved network access for latency sensitive access categories and/or access categories that are considered important to an enterprise system with minimal disruptions to these sessions.

1. A non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, cause performance of operations comprising:
determining a category, of a plurality of categories, for a current session for a first client device associated with a first access point, wherein each category, of the plurality of categories, is associated with a minimum Signal-To-Noise Ratio (SNR) threshold of a plurality of minimum SNR thresholds; identifying a particular minimum SNR threshold, of the plurality of SNR thresholds, associated with the category for the current session; determining whether wireless signals received from the first client device meet the particular minimum SNR threshold associated with the category for the current session; responsive to determining that the wireless signals received from the first client device do not meet the particular minimum SNR threshold associated with the category for the current session, causing the first client device to associate with a second access point different than the first access point; responsive to determining that the wireless signals received from the first client device meet the particular minimum SNR threshold associated with the category for the current session, refraining from steering the first client device to associate with the second access point.
