hi, there, i am running several srm related script files under tcl/ex directory( srm-star.tcl, srm-adapt-req(p).tcl. i look at the statistics data generated by the scipt( srm-avg-info ). there are lots of entries( rep-delay, req-delay, rep-dup, req-dup ) are negative. does anyone have any clue why those data can be negative? Any comments would be greatly appreciated. regards, yan
