Re: [BEHAVE] Fwd: I-D Action: draft-chen-behave-nat64-radius-extension-00.txt

Hi Tiru,

You are right. Please check the sentence in the draft "It's also
   possible to extend Port Control Protocol (PCP) to support those
   network information queries from external servers. ....."

The radius-based proposal intended to fit into the environment, where
geo-location system is already deployed based on a radius
database[RFC5580]. Some benefits have been described related to this
context.
1) radius-based solution would be a in-band solution
2) fewer impacts to NAT64 performance because the process is
independent with NAT64 translation

>> Abstract:
>>    This document proposes new radius attributes for stateful NAT64.  The
>>    extensions are used to provide geo-location services with an exact
>>    IPv6 soruce address.  The message flow to deliver the NAT64 binding
>>    information between radius clients and servers is also described.
>>    Therefore, accurate location could be traced out depending on the
>>    radius method.
