eap Mailing List: RE: Updated version of EAP-based network discovery draft

[Ruffino Simone (Simone.Ruffino]

Hi Farid,

I've read through the last version of the draft and it seems to me very clear, 
in the overall. I've some comments regarding the "Implementation 
considerations" section (Sec. 4), though I realize this is not intended to be a 
"recommendations" section...

1) (editorial) It states:
"However, delivery mechanism options 1 and 2 are recommended as they are 
backward-compatible with the currently-deployed APs."

Do you mean here method 2 and 3 ? Method 1 is actually not backward compatible.

2) In "- When Option 3 is used " bullet:

2a) "if the RADIUS proxy/server still cannot route the RADIUS packet the next 
AAA hop based on the realm portion of the NAI, "

Maybe I'm confusing here, but in step 6. it states that the wireless client 
either chooses one of the MNs, or it does not connect to the access network. 
So, why the RADIUS proxy/server could not route the RADIUS packet ? 

2b) "then it MAY route the packet based on its local routing policy, or it MAY 
discard the packet."

If the mediating network chosen by the user is not available, then the 
authentication request SHOULD (and maybe MUST) not be forwarded. This because 
wireless clients, choosing a preferred network, implicitly indicate that they 
don't want any other network to route their request. If the authentication 
completed, the wireless client would not be able to know that the chosen 
network is not available.
So I propose to change the statement in the following way : ", then it SHOULD 
discard the packet."

Best regards,
Simone
