Hello Ferenc, The big picture is to put voice in EF class, have AF classes & BE class. Asterisk can mark packets, but I'm marking with 'iptables' & classifying (filtering) as per the requested help. We want HTB for EF class to guarantee the bandwidth & to be able to borrow/lend between classes should there be no voice or data on the link. We are looking to roll this out at many sites & to partake in DS domains, hence the need to fully understand DiffServ. . My biggest issue was understanding how to filter packets to their correct classes, then I found this: http://kabru.eecs.umich.edu/qos_network/diffserv/DiffServ_prototype/qdisc and explained very nicely: http://kabru.eecs.umich.edu/qos_network/diffserv/DiffServ_prototype/setting_qdisc.ps What you have shown me is good, it's simpler & will work just as well. Look at the above link for the script, I would like to run something like that but with HTB & PFIFO for the EF class. Their explanation helps, I'm busy trying to put something together now. I haven't tried to remark packets yet so I'm unsure as to what the exact procedure is. What frustrates me is that there is no debug or logging to test scenarios. Has anyone done voice HTB with EF, AF & BE classes?
