Scavenger is more about *when* it > works than about how well, IMO. again, my fault for twisting the references around. I meant to refer to Y.1571 as for scavenger service, it uses resources not used by best effort or better than best effort flows. so, if we assume a transit node only supports best effort, then during bursty spikes in load will allocate available resources to BE at the expense of scavenger service. that may be a case of "when", but the result is a service below that of BE since you are not relying on random drop or drop from head schemas. outside of scavenger service, I know of another on-going proprietary effort at lower than best effort service. regards, -ken
