That’s fair enough. It sounds like the fairly coarsely discrete time intervals in PIE are the main justification for this particular heuristic, so it might be sufficient to document that WRT PIE itself. Using finer time intervals is clearly a better choice for the future. - Jonathan Morton _______________________________________________ aqm mailing list [email protected] https://www.ietf.org/mailman/listinfo/aqm
