One question about TCP small queues (which I don't think is a good solution to the problem). For 802.11 to be able to perform well it needs to form maximum size aggregates. This means that it needs to maintain a minimum queue size of at least 64 packets, and sometimes more. Will TCP small queue

Some level of hardware queueing is necessary to meet the response time. It's further complicated by the need to include retries at the start of the next aggregate, but you only learn which ones from the block-ACK received after the last one. Given the hardware's need to have frame length well b

Interesting to note that sfq-codel's reaction to a non conforming flow is of course to start dropping more aggressively to make it conform, leading to the high loss rates for whatever is hashed together with a VoIP flow that does not reduce it's bandwidth. One downside to SFQ really. Simon O
