A couple of quick questions about using priority queuing. I am doing experiments with ad hoc routing protocols and I want to ultimately have 3 or 4 classes of traffic. At present I am using the default pfifo_fast queuing discipline on the wireless interface with 3 classes of traffic and with a 100 packet buffer on the interface. 1) Is there a way to allocate a fixed amount of buffer space to each of the 3 bands with pfifo_fast? I suspect not, but I don''t see any documentation on this. My guess is that it is one big block of memory that could be filled by lower priority packets and reject new higher priority packets when full. I think we have encountered congested situations where higher priority traffic may be blocked because the buffer is full of lower priority packets. Will this be true? 2) I want to eventually replace this pfifo_fast queuing discipline with the prio queuing discipline with 4 bands and with defined amounts of buffer space allocated to each band when I understand how to do it. The examples I have seen in the HOWTO for configuring this seem to indicate that the prio queuing discipline automatically comes up with 3 bands, but I didn''t see any examples of tc commands to configure additional bands or allocate buffer to the bands. Is this possible and is there a tc document that provides the necessary commands? Or could you show me the necessary commands? Thanks for the help.
