Hello I was reading a howto named: Linux - Advanced Networking Overview Version 1 Saravanan Radhakrishnan Information and Telecommunications Technology Center Department of Electrical Engineering & Computer Science The University of Kansas Lawrence, KS 66045-2228 Some parts of the index: Disclaimer Introduction QoS Support in Linux Introduction Configuration Implementation Basic Principle Queuing Disciplines Classes Filters Interface between the kernel and user space Usage - tc Queuing Disciplines Classes Filters Class Based Queue Diff-Serv queues Route Classifiers u32 Classifiers Example - 1 : CBQ with route classifiers Example - 2 : CBQ with u32 classifier References About this document ... It's a great one but the best part of it, at least for me, were the example that came with a small ascii chart o a graf about the configuration, it helped me to "visualise" the configuration. Fisrt of all I want to say that I'm not a Linux/ip/tc guru. Just what to make something that could be of a utility for all. So what I'm trying to do is collect the most configuation examples I can about (ip, tc, cbq.init, etc) to make a document of examples. Maybe someone else is doing this or is interested in doing it or maybe it's allready done and I haven't seen it, if so please say me where I can find it, thanks. I'm offering myself to collect this info and make a doc, or hand it over to some with experience in writing, there is no problem for me. you think this could work? bye billy
