FW: Dummynet and bursting!

[Javier -]

 This is the literal command executed:





 /sbin/ipfw pipe {$bw_up_pipeno} config bw {$bw_up}Kbit/s burst 500000 queue 500Kbytes



 The output from ipfw pipe show:



 20010: 1.049 Mbit/s 0 ms burst 500000
 q151082 500 KB 0 flows (1 buckets) sched 85546 weight 0 lmax 0 pri 0 droptail
 sched 85546 type FIFO flags 0x0 0 buckets 1 active
 0 ip 0.0.0.0/0 0.0.0.0/0 45 2832 0 0 0


 When download a file the speed is the same (browser shows 125kbytes/s , ok for 1mbit) at the start and after 500kbytes transfered...



 I´m using Pfsense 2.0, 8.1-RELEASE-p6 , captive portal creates the commands for ipfw, and i want to modify them in order to support bursting...


 Thanks!

Any help/comment wll be appreciated...specially from Luigi! Is he alive on the list? Regards! _______________________________________________
