This draft is well written and in fact provides a wonderful overview of MANET. The draft updates RFC5444 based on some operational experience (and thanks for that); though it does not specify a protocol it is constraining RFC 5444 implementations hence the “updates” header. From a security perspective this draft seems fine; there is one security-related update and it is explained in the security considerations. From a non-MANET expert perspective, I have to admit that I found it hard to figure out exactly what is being “updated”. It’s a style thing that I’m not hard over on, but an informative section explaining what got changed would have really helped this reader. I will note that there are a couple of places where the draft is clear that is updates 5444, e.g., s4.4.1, s.4.6, so I have to wonder are those the only update? Or, is it that all the 2119 requirements for the processing rules update 5444 and you’d only look in 5444 for the packet formats?
