Limited bandwidth 2. Specified propagation delay which affects each packet going out of an interface 3. Limited bucket size (send buffer) for each interface. I know how to do no. 1 using CBQ. What about 2 and 3 ? I haven't seen any qdisc that deliberately imposes a specified delay. How can the send buffer size be changed ? I can see its current value in the 'ifconfig' output, under 'txqueuelen', but I don't know how to modify it.
