Nope. I went single channel for the yurtlab backbone in part because I wanted "hardware flow control" (the 100Mbit ethernet connected to a 300Mbit radio) to work and to be able to look at what the "microqueues" in the ethernet driver formed by packet de-aggregation did under fq_codel. Doing it all in one box with (nonexistent) software flow control between 2.4ghz, 5ghz, and gigE ethernet in a single unit - seemed likely to do nothing more than pass bursts of packets around. I like the software-fq-on-de-aggregation idea I talked about a week or so back, but haven't done anything about it. I'd thought hard about using the http://www.ubnt.com/rspro rather than the netgears at one point, but thought the BOM would put people off, and at the price tag for a full box, there seemed to be several x86 alternatives, and either way, we ended up with no micro queues to break up. A typical configuration at the yurtlab is two nano station M5s and a single omni 2HP. --=20 Dave T=E4ht Fixing bufferbloat with cerowrt: http://www.teklibre.com/cerowrt/subscribe.= html
