Re: [MEXT] Reviews of draft-korhonen-mext-mip6-altsec

Hi Jouni and Raj,

I quickly reviewed draft-korhonen-mext-mip6-altsec-06.txt. 

This document is well-written and can be easily read. 
I can't find any technical issues in the protocol definition. 

Here are some questions/comments.

1. How to define data traffic selector for encryption? 
IPsec has IPsec policy DB to decide which traffic should be applied encryption.
How can we apply encryption for certain data traffics? Is this up to implementation?

2. In Background.
In the early era of MIP6, signaling message was carried in IP header options. 
One of big reasons we can apply SSL for MIP security is that MIP has message type.
Nowadays, there are specs not even using MH message type.
RFC5844 carries MH encapsulated in UDP. Now you also carry MH messages in UDP. 

3. In 5.7.3, why not adding one entry for MNP. It can support NEMO without big change;-)

4. When I first read it, I prepared for many questions about RO signaling. At the very last of draft, it said RO is out of scope:-)
Can you explicitly mention it a bit earlier? Maybe you can add one sentence at the definition of  Binding Management Messages in Section2.

Non of alternate security mechanism (RFC4285 and this) support RO signaling. Is it MEXT WG strategy for alternate security discussion?
Although I am not such fun of RO, I want some clarification on this.

regards
ryuji
