Re: [DNA] Considerations for DNA Schemes with multiple Interface andLayer 2 Technologies

[JinHyeock Choi <jinchoe@gmail.com>]

Dear Yong-Geun

I think that the case 3.2, 'Single interface with Make before Break'
will affect DNA solution design. I agree that we are not familiar with 
this case, so it would be of much help, if you elaborate the below
with more detail. 

     We think that we are not familiar with this case. But in CDMA[7], a
     mobile station can access two or more different base stations
     simultaneously. In this case, a host can make a new link-layer
     connection before an old link-layer connection is torn down.

Especially I wonder whether it's possible for a host to distinguish 
the IP packets from the old link-layer connection FROM the ones
from the new link-layer connection.  

However, it's not clear to me the relationship between 'DNA schemes' 
and 'multiple interfaces' from Case 3.3 & 3.4 description. I still 
can't see how multiple interfaces would affect DNA schemes 
substantially. Kindly elaborate this more. 

Thanks for your kind consideration. 

Best Regards
