I think that there are no qdiscs that permit to drop the oldest frame of a queue when this queue is full, but I would like to be wrong: bfifo drops arriving frames when the max queue length is reached. red also drops arriving frames in a more elaborate fashion, with a drop probability that increases above a limit and becomes a drop certitude when the max queue length is reached. sfq drops "fairly", it piles frames with same (ip source, ip dest, port source and port dest) and drops a frame from the biggest pile to favour the smaller flows. But I cannot find the qdisc that reacts like a bfifo or red qdisc but drops the oldest message of the queue when a drop is needed. Even better: a qdisc with an autodestruct algorithm for each frame in the queue that would garantee the "freshness" of each frame coming out. If you know of such qdiscs, please share. _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
