The approach $dayjob went with is to classify customer traffic into 3 queues plus one for network control, and then do RED with a size-limited queue per subif. It works well when traffic gets classified correctly. Tuning RED is challenging and it is tempting to increase buffer size to give RED a bit more of a chance to react smoothly. Even so, one aggressive flow can be quite detrimental to everything else in the samme traffic class. fq-codel would achieve better results with much less work. /Benny _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
