Traffic Shaping Limitations
Nullity last edited by
ALTQ shaping is not capable of setting an upper limit on traffic. Use Limiters for controller upper limits.
but HFSC explicitly has an "upper-limit". I dunno about other ALTQ algos but the quoted statement doesn't seem accurate. (ALTQ itself has an upper-limit on a per-interface basis with it's Token Bucket Regulator, but that's likely not what the quote is referring to.)
Some clarification regarding why limiters are being advocated over ALTQ for per-queue upper-limits would be useful.
