RE: [LARTC] Priority Queueing on Linux
Title: Message You can use the prio options in qdisc and channel traffic thro' different qdiscs. Another option is to set TOS marks and route to qdiscs using the mark filters in u32 classifier. Why don't you look up http://www.docum.net . Staf has a good site going. I've benefitted from it.

You configure four traffic priorities. You can define a series of filters based on packet characteristics to cause the router to place traffic into these four queues; the queue with the highest priority is serviced first until it is empty, then the lower queues are serviced in sequence. -- Michael T.

Re: [LARTC] Priority Queueing on Linux
Title: Re: [LARTC] Priority Queueing on Linux Hi, Below is the explanation of priority queueing http://www.cisco.com/univercd/cc/td/doc/cisintwk/ito_doc/qos.htm#xtocid22 I am developing a linux router. There is both data and voice traffic passed thru it. When I use priority queueing on Cisco router, the voice quality is good, evening downloading a large file. But I use the following tc config, the voice quality is not smooth when downloading a large file: tc qdisc add dev ppp0 root handle 10: cbq bandwidth 112Kbit avpkt 1000 tc class add dev ppp0 parent 10:0 classid 10:100 cbq bandwidth 112Kbit rate 57Kb it allot 1514 weight 5Kbit prio 2 maxburst 20 avpkt 1000 isolated tc class add dev ppp0 parent 10:0 classid 10:200 cbq bandwidth 112Kbit rate 55Kb it allot 1514 weight 5Kbit prio 8 maxburst 20 avpkt 1000 bounded tc qdisc add dev ppp0 parent 10:100 sfq quantum 1514b perturb 15 tc qdisc add dev ppp0 parent 10:200 sfq quantum 1514b perturb 15 tc filter add dev ppp0 parent 10:0 protocol ip prio 2 u32 match ip tos 0x8 0xff flowid 10:100 tc filter add dev ppp0 parent 10:0 protocol ip prio 8 u32 match ip tos 0x00 0xff flowid 10:200 voice packet is tagged with 0x8 in TOS field. Voice traffic only uses 34K bandwidth. So the bandwidth allocated to voice is enough. Is there any better tc config? -- Date: Tue, 9 Jul 2002 11:46:58 +0200 From: bert hubert <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Re: [LARTC] Priority Queueing on Linux On Tue, Jul 09, 2002 at 12:02:40PM +0800, Patrick Chan wrote: > There is priority queueing in Cisco router. > > Is there any equivalent implementation for TC on Linux? > > If yes, how can I configure and can you give me example? Please dig up a link so we can see what 'priority queueing' actually *is*. But I bet that tc has it.

it is the same as PRIO queue in linux tc. devik On Tue, 9 Jul 2002, bert hubert wrote: > On Tue, Jul 09, 2002 at 12:02:40PM +0800, Patrick Chan wrote: > > There is priority queueing in Cisco router. > > > > Is there any equivalent implementation for TC on Linux? > > > > If yes, how can I configure and can you give me example? > > Please dig up a link so we can see what 'priority queueing' actually *is*. > But I bet that tc has it. > > Regards, > > bert > > -- > http://www.PowerDNS.com Versatile DNS Software & Services > http://www.tk the dot in .tk > http://lartc.org Linux Advanced Routing & Traffic Control HOWTO > ___ > LARTC mailing list / [EMAIL PROTECTED] > http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/ > > ___ LARTC mailing list / [EMAIL PROTECTED] http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
