Hi, Sebastian, 
 
Thanks for reviewing the draft.  A slightly updated version of draft is
available for review now
(http://bgp.potaroo.net/ietf/ids/draft-singh-netlmm-protocol-00.txt), 
Please find below my inline comments. 
 
Regards,
Ajoy

             The logical localized mobility management model proposed by
this draft has the following essential benefits:

		a.   Allow a separation of the signaling and the bearer
plane  
		b.   Signaling plane for binding updates  
		c.    Bearer plane tunnel for  information transfer  
		 
		Ajoy-> This is a key concept and even SDOs (3GPP/WIMAX
etc.)  are moving in this direction. For example,  3GPP has defined MME
and UPE. MME and UPE are respectively responsible for control and bearer
plane processing. Similarly, WIMAX has defined similar concepts such as
DP and EP. If the PMIP protocol is defined to provide separation between
B P  and CP, it will be simpler to map its implementation to the split
architecture. 

		d.    Allow CMIP (Client Mobile IP) for nomadicity or
global mobility  
		 
		 Ajoy-> Absolutely client based mobility solution is in
better position to do inter-domain mobility. In our draft, we have
defined how PMIP and CMIP can co-exist together. 
		 
		 e.  Compliant with the standard mobile IP requirements 
		 
		Ajoy-> This is a very important point. We want to define
PMIP protocol with minor changes to existing MIPv6 HA.  
		 
		 f.   Centralized PMIP (Proxy Mobile IP) agent
deployment supported to efficiently manage state information, for
mobility across access routers 
		 
		Ajoy-> Centralized PMIP agent avoids context transfer of
security key and other control plane state information between ARs
during handoff.  Also, centralized PMIP agent will provide better
handover performance because we do not have to bootstrap security  key
during every PMIP handoff.  

                These benefits are aligned with the developments across
SDOs in terms of the objectives for the evolution of wireless mobile
access networks. 
 
            Ajoy-> Agreed.
