...wizards. It''s mainly from the source code. 1. What is the cell_log ? (its everywhere in the code) 2. Why does htb calculate its burst(buffer) with tc_xmit_time() ? Is opt.rate.buffer supposed to have the time it takes to transmit the packet ? (in q_htb.c around 223 lines) 3. What does rtab and ctab arrays do ? And what kind of value should be in there ? (its set in tc_core.c tc_calc_rtable()) I''d really appreciate your help. Thankyou very much in advance.

lartc-request,hello! 　　 I find a line in tbf_change() in sch_tbf.c: ptab = xchg(&q->P_tab, ptab); Can I consider that the pointers are exchanged between q->P_tab and ptab? as following: prev=q->R_tab; q->R_tab = rtab; rtab = prev; Is my understanding righ? ======= 2002-03-23 12:01:00 you wrote:======= >Send LARTC mailing list submissions to > lartc@mailman.ds9a.nl > >To subscribe or unsubscribe via the World Wide Web, visit > http://mailman.ds9a.nl/mailman/listinfo/lartc >or,...

The HTB scheduler code is a mess, this patch set does some basic house cleaning. The first four should cause no code change, but the last two need more testing. -- Stephen Hemminger <shemminger@osdl.org> "And in the Packet there writ down that doome" - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to

Hi all, ive got 2 internet connections set up via the nano howto (which are working great) and we are running NAT. Was looking in to qos mainly to stop large http downloads/ftp downloads from hogging the line so that browsing for other users doesnt slow to a crawl, but if the line is free and no one is doing anything then for it to use the available bandwith. The wondershaper sounded exactly what
