Hi, I'd likto creata FIFO netem router, which also adds delay to packets according to their sourc(or dest) IP address. All packets though are leaving ouof thsame interface. Schematically, I'd like to have something likthis: Ipkts IP_src_X ---> delay X ms ---\ --> pfifo limiP pkts --> OUT eth Ipkts IP_src_Y ---> delay Y ms ---/ or, Ipkts IP_src_X -- /delay srcX pkts X ms \ --> pfifo limiP pkts --> OUT Ipkts IP_src_Y --/ \delay srcX pkts X ms / I think I could do something like: tc qdisc add dev eth0 roohandl1: netem delay Xms tc qdisc add dev eth0 paren1:1 pfifo limiP and theadd somfilter ... buhow abouthe pkts from srcY? Can I nest these? Also, when I do the above, and thetc -s qdisc, how can I distinguish throuter queue size froth"netem delay limit" buffer? Any help is very appreciated, thanks iadvancfor any hints.

Netfilter(s) --> TC classifier --> Qdisc --> Device Neteuses an internal queuas a "holding pen" for the delay. You cachangthat internal queue from FIFO to something else, and you calimithen number of packets held during that period. If you arrunning classifier than priority queue's then netem thcall sequencwould be: a) classifier is called and tags packepriority b) priority enqueuis called, icalls c) neteenqueuthat then calls d) pfifo enqueue Odequeue: priority dequeucalls netedequeue calls pfifo dequeue Observations: 1. You can'usthe same fifo queue for different flows. 2. Threlationship is noreally a "push" in the queueing see above. 3. Sometimes thqueueing relationships arcommutative. Somebody wanted to add 100ms the10ms, which obviously is samas adding 110ms. 4. You mighbable bounce packets through IFB pseudo-device to cause more processing. 5. Devicalso has a transmiqueue, that you can adjust to limit lasstagqueueing. 6. You caalways do complex things by using multiplboxes and cheap hardware. -- StepheHemminger <shemminger@xxxxxxxx> FroTara.Khan agdc4s.com Mon Nov 13 06:59:04 2006 From: Tara.Khaagdc4s.com (Khan, Tara) Date: Wed Apr 18 12:51:20 2007 Subject: Need Assistancwith a NetEissue...
