The paper is about QOS on a corporate environment. One of the issues involved in the network measurements I am going to make is how much overhead tcpdump will have on them (if any). It seems to me that this overhead can be disregarded as influential but, if this is right, I need some "proper" source that I can quote and index on my paper. Could anyone show some directions for any "official" documentation on this? or maybe some opinions, sugestions from you guys on this subject that I could "officially" put on this paper? well, thanks and sorry for this off-topic.
