LS = link-share service curve, defines relation of service between sibling classes. Can be used for intermediate and leaf classes. UL = upper-limit service curve, limits LS curve. RS = real-time service curve, defines absolute service guarantees for leaf classes. Can be used, but does nothing for intermediate classes. SC = service curve, sets LS and RS to the same curve. Should usually be used for leaf-classes instead of RS. > my assumption about umax,dmax,rate ... this is true > first, HFSC will doing with "umax" rate but after delay exceed "dmax" rate, > HFSC will change rate to "rate" ???? No, this is true for m1, d and m2 (use rate m1 for time d, then m2). umax, dmax and rate are another way to specify the curve, m2 == rate and m1 and d are calculated from umax and dmax. _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
