Classes must have guarantied rate calculated from 115kbit possible rate (for example 3 classes) and the possibility to borrow up to 1mbit (depends on ISP side). If it's impossible, than how to define additional class for excess bandwidth from 115kbit up to 1mbit? Can be other classfull or classless qdisc used in this case? Very hard, it maybe, depending on the link behaviour over time and exactly how your ISP does the shaping, be possible to detect what rate traffic is arriving at with policers and mark accordingly.

According to tc-htb man page, if we set PRIO parameter, then after supplying the packets to satisfy the RATE of all classes, the HTB first sends the available packets to LOWEST PRIO class and so on. In this case if the above class 1:20 with PRIO 0 requests packets, than the class 1:30 must receive only 1kbit (the specified RATE), nothing more. In practice class 1:30 shares the bandwidth with class 1:20 and gets not 1kbit, but much more >20kbit. I have TSL 2.1, kernel 2.4.27-3tr.

Hi everyone, and thanks for your help so far. I have been playing around with tc and htb for a couple of weeks now, and while I am nowhere near understanding everything here, I am beginning to know more about packets than I ever wanted to know. I have two university buildings with a 1mb connection to the Internet.

They have to share the connection with all the students on both sides, and the traffic the teachers create. So the people in admin have a hard time connecting to their database. What I have done so far is to create two leaves 1:10 and 1:20 and filtered the traffic going to the database on the far end. What the admin there would like is, that the connection is fully available for everyone, until the secretary wants to look something up on the database. Then it should have top prority and all the other traffic should virtually stop. I managed to apply the filters and have the packets ending up in the right leaf.
