Summary:Sizing Internet buffers has recently become a popular topic. While Internet connections have become larger in bandwidth, latency has increased - and latency is a crucial factor for the performance of the applications running over the Internet. Several proposals have been made to reduce the buffer size and thereby also latency, mainly by focusing on the core routers in the Internet's backbone. However, little has been done to investigate buffer sizing on access links (known as bufferbloat problem), and more specifically in 802.11 access points. The nature of an 802.11 channel makes buffer sizing issues different than in wired networks because of the frequent changes in the service time due to changes in the bandwidth and delay - caused e.g. by rate adaptation (RA) due to noise, interference and contention as well as the DCF mechanism. In this paper, we briefly present our latest efforts to investigate AP buffer sizing in 802.11 networks.
