Recent Linux kernel updates have turned on the light again on the needs to reduce network latency in any environment, in particular in Wireless LAN.

Abstract
Recent Linux kernel updates have turned on the light again on the needs to reduce network latency in any environment, in particular in Wireless LAN. After the bufferbloat problem definition, many TCP congestion controls have been developed, different queueing algorithms have been deployed and advanced updates on wireless drivers and TCP modules have been reported as well. The contribute of this paper is to present and analyze through real extensive experiments these advanced new solutions highlighting a configuration able to limit a WLAN latency to a value close to 1ms. This result is one order of magnitude lower than the previous literature study and enables WLAN technology to support ultra-low latency communication.
