It uses the OSI conceptual model. Subsequent editions of that book suck, because they introduce a bunch of fashionable IETF protocols but skimp on the principles that lie behind the design of the protocols, giving the student a bunch of buzzwords but no real intellectual framework to place them in. > as I've mentioned before PPP is an example written since rfc > 1122-23. In particular, PPP (it's an HDLC replacement! A tunnelling protocol! An authentication accessory! A floorwax! A desert topping!) is a bad example of _anything_ as far as layering is concerned I am, however, looking forward to reading this draft Bill is talking about writing. Based on previous form, I'm expecting it to contain at most two paragraphs of content, and lead to lots of pointless followup discussion.
