My problem is that I don't know how much available bandwidth I have (this is about wireless networks). Otherwise I could just calculate the total throughput on the interface and see if there is some free bandwidth left. Can one with linux traffic control tools or iptables derive the load of interface/queue? The only thing I need to know is whether the output transmission queue can cope with all the traffic waiting for transmission, in other words, is the queue full loaded or not.
