I'd like to make a suggestion to the Advanced Routing HOWTO. I have read parts of it some months ago and I had a hard time following it and I think that I know the reason: the HOWTO doesn't give the background on the subjects it discusses. This difficulty was particularly evident when I was reading the part about Quality of Service/Bandwidth Shaping. I got the impression of that section of the HOWTO being a handful of commands, with arguments that I didn't understand completely (and often asked myself if they were important or why they were important). Especially the *why* questions I asked myself are an indication that I lack the background of the mechanics of setting a QoS based service (of course, I would not ask myself why if I were already convinced of the importance of any command or argument). So, here is my input: if possible, please, include a bit of theory behind the concepts, so the readers of the document get the big picture before going to the technicalities. If more information about my doubts is needed, please let me know and I'll gladly answer, if I can help make this document better for the community. Thank you very much, Roger... -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Rogerio Brito - rbrito@xxxxxxxxx - http://www.ime.usp.br/~rbrito/ =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
