Sir/Ma'am,

My name is Ron Smith and I am a Cyber Warfare Instructor for the DoD and we
reference many of the RFCs on your site frequently throughout the course of
our instruction. One issue I'm having is that we reference a 4 layer TCP
model based on a couple of RFCs but I keep finding references to a 5-layer
model.  In fact, one of the tools we use, Wireshark, also utilizes
dissectors based on the 5-layer model.  Is there an updated RFC or some
guidance that pertains to this updated model?

v/r
Ron Smith
